DIRECTIONS

Read both passages carefully. Annotate as you go—underline evidence, circle clues, draw arrows between connected ideas across passages. Every question requires inference: do not look only for sentences that directly answer the question. The answer is always built from evidence, but it is never stated outright. For written responses, construct your reasoning step by step.

PASSAGE A: OCEAN PLASTICS — THE SCALE OF THE CRISIS

[A1] Every year, approximately eight million metric tons of plastic enter the world's oceans. To visualize this number, scientists sometimes compare it to dumping one garbage truck full of plastic into the ocean every single minute—day and night, without stopping, for an entire year. The plastic does not disappear. It breaks into smaller and smaller pieces called microplastics, but it does not dissolve or go away.

[A2] Seabirds, sea turtles, dolphins, and fish mistake plastic bags and bottle caps for food. When they eat plastic, it fills their stomachs without providing any nutrition. Many animals starve to death even though their stomachs are completely full. The plastic also carries toxic chemicals that build up in the bodies of animals over time—a process scientists call bioaccumulation.

[A3] The Great Pacific Garbage Patch is perhaps the most famous example of ocean plastic accumulation. Despite its dramatic name, it is not a solid island of trash. Instead, it is a vast region of the Pacific Ocean where ocean currents concentrate plastic debris into a diffuse, soupy mixture. Most of the plastic in the Garbage Patch is invisible to the naked eye—tiny microplastic particles suspended just below the surface. The patch covers an area roughly twice the size of Texas.

[A4] Scientists estimate that if current trends continue, there will be more plastic than fish in the ocean by weight by the year 2050. Yet plastic production is increasing, not decreasing. In 2020, humans produced roughly 367 million metric tons of plastic—more than the total weight of all humans alive on Earth. Finding solutions requires understanding not only where the plastic comes from but why it is so difficult to stop.

PASSAGE B: THE PLASTISPHERE — LIFE IN THE GARBAGE

[B1] In a discovery that surprised even veteran marine biologists, scientists have found that the microplastic fragments floating in the world's oceans are not barren surfaces. They are colonized—inhabited by complex communities of bacteria, algae, fungi, and tiny animals that have found in plastic a new kind of home. This unexpected ecosystem is called the plastisphere.

[B2] The plastisphere presents scientists with a difficult ethical dilemma. On one hand, the plastic itself is unambiguously harmful to ocean ecosystems—it kills wildlife and poisons food chains. On the other hand, the communities of microorganisms living on plastic have developed their own interdependencies, food webs, and ecological relationships over the decades since plastic entered the ocean in large quantities. Some scientists warn that aggressively cleaning up microplastics could destroy the plastisphere communities that now depend on them, adding a second layer of ecological disruption to the first.

[B3] More alarming still, the plastisphere may be serving as a vehicle for the global spread of invasive species. Microorganisms and small invertebrates that colonize plastic fragments can travel thousands of miles on ocean currents, arriving in ecosystems where they have no natural predators and may outcompete native species. This mechanism—sometimes called "plastic rafting"—represents a new and poorly understood pathway for biological invasion that did not exist before humans introduced durable plastic debris into ocean systems.

[B4] The plastisphere also appears to harbor bacteria that have evolved the ability to break down certain types of plastic—a discovery that has generated enormous scientific excitement. However, researchers caution that plastic-eating bacteria, even if deployed at scale, would likely take decades to make a meaningful dent in existing plastic accumulation, and that the bacteria themselves could have unforeseen ecological effects if introduced into ocean ecosystems in large quantities.

SECTION A — SINGLE-PASSAGE INFERENCE (2 pts each)

Questions 1–8: Draw conclusions, infer main ideas, identify author motivations, and detect authorial assumptions from within individual passages.

1. [Logical Conclusion] Paragraph two of Passage A states that animals eating plastic have stomachs that are "completely full" yet they starve to death. What conclusion can you draw about the relationship between feeling full and actually being nourished?

DOK 2 · CRM B-2

▸ Infer consequence of a described biological process.

A) Feeling full and being nourished are identical biological states; animals that feel full are always receiving sufficient nutrition

B) Feeling full is a physical signal produced by stomach volume, while nourishment depends on the chemical content of what fills the stomach—plastic triggers the fullness signal without delivering any usable energy, proving that the two states can be completely decoupled

C) Animals that eat plastic eventually develop a tolerance for it and can begin extracting trace nutrients after several weeks

D) The starving animals must also be avoiding water, since dehydration rather than plastic consumption is the true cause of their decline

2. [Implied Main Idea] Passage A never states its main idea in a single sentence. Based on all four paragraphs together, what main idea is the author implying?

DOK 2 · CRM B-2

▸ Infer unstated main idea across all paragraphs.

A) The Great Pacific Garbage Patch is the world's most urgent environmental problem and should be the focus of immediate cleanup operations

B) Ocean plastic pollution is an escalating, multi-layered crisis that threatens marine ecosystems and human food systems, and whose solution requires more than what current efforts provide

C) Scientists have failed to communicate the severity of ocean plastic pollution to the public and governments

D) Individual consumer choices are the primary driver of ocean plastic pollution and personal responsibility is the most important solution

3. [Authorial Assumption / Gap] Passage A's final sentence states that "finding solutions requires understanding not only where the plastic comes from but why it is so difficult to stop." What assumption does the author make here without defending it?

DOK 3 · CRM C-3

▸ Identify an undefended assumption in the passage.

A) The author assumes that all plastic pollution comes from land-based sources rather than fishing vessels or offshore industry

B) The author assumes that intellectual understanding of a problem automatically leads to effective action—without explaining the mechanisms by which understanding translates into policy change, corporate reform, or behavioral shifts

C) The author assumes that no solutions currently exist and that the field is starting from scratch

D) The author assumes that the reader already knows why plastic is difficult to stop and is simply reminding them

4. [Prediction / Projection] Based on Passage A's data about plastic production trends, what is the MOST reasonable prediction about the state of ocean ecosystems in 2050 if no major policy changes occur?

DOK 3 · CRM C-3

▸ Predict a future outcome using passage logic.

A) Ocean ecosystems will have recovered naturally by 2050 because fish populations adapt faster than plastic accumulates

B) Plastic will outweigh fish in the ocean, bioaccumulation of toxins in the food chain will have intensified across multiple species levels, and marine biodiversity will have declined significantly—with cascading effects on human food security for populations dependent on seafood

C) Governments will have implemented a global plastic ban by 2035, so the 2050 projection is unlikely to materialize

D) The Great Pacific Garbage Patch will have solidified enough to support scientific research stations by 2050

5. [Character / Author Motivation] Why does the author of Passage A describe the Great Pacific Garbage Patch as "not a solid island of trash" before explaining what it actually is?

DOK 3 · CRM C-3

▸ Infer the purpose behind a rhetorical choice.

A) The author wants to correct a scientific error made by previous researchers who described it as a solid island

B) The author anticipates a likely misconception the reader holds—that "garbage patch" implies a visible solid mass—and strategically dismantles it first, because the invisible nature of microplastics makes the problem harder to grasp and therefore harder to motivate action around; correcting the misconception is itself an act of persuasion

C) The author is legally required to correct popular misconceptions before presenting scientific data about ocean pollution

D) The description of what the patch is not makes the passage longer and more detailed, which increases its credibility as a scientific text

6. [Logical Conclusion] Based on Passage B's description of the plastisphere, what can you conclude about our ability to predict all the consequences of introducing a new material into a natural environment?

DOK 2 · CRM B-2

▸ Draw conclusion from the plastisphere discovery.

A) We can fully predict the consequences of new materials through computer modeling before they are introduced into natural environments

B) The plastisphere demonstrates that complex natural systems respond to new inputs in ways that are genuinely unpredictable—even veteran scientists were surprised by the discovery—suggesting that the long-term consequences of introducing novel materials into ecosystems cannot be fully anticipated in advance

C) The plastisphere proves that natural ecosystems are more resilient than scientists previously believed and can always find a way to adapt to human pollution

D) The consequences of introducing new materials can be predicted if sufficient time for scientific observation is allowed before any cleanup efforts begin

7. [Implied Main Idea] What is the central tension that Passage B implies but never directly states as a thesis sentence?

DOK 3 · CRM C-3

▸ Infer the central tension of Passage B.

A) The tension between plastic-eating bacteria as a solution and the decades they would take to make a meaningful difference

B) The tension between the urgent need to remove plastic from the ocean and the ecological risks of doing so—illustrating that in complex systems, well-intentioned interventions can create new problems as serious as the ones they address

C) The tension between different scientific disciplines' approaches to the plastisphere, with marine biologists and microbiologists disagreeing about its significance

D) The tension between the scientific community's excitement about the plastisphere and the public's continued indifference to ocean plastic pollution

8. [Authorial Assumption / Gap] Passage B warns that cleaning up microplastics could "destroy the plastisphere communities that now depend on them." What foundational value judgment does this warning assume, and is this assumption explicitly examined anywhere in the passage?

DOK 4 · CRM D-4

▸ DOK 4: Identify a foundational assumption underlying the ethical dilemma in Passage B.

A) The warning assumes that all human-caused environmental changes are automatically harmful; this assumption is explicitly examined in paragraph two through a discussion of the history of environmental ethics

B) The warning assumes that the ecological integrity and preservation of any established community of living organisms—even one created accidentally by human pollution—has moral and scientific value that must be weighed against the harm of removing it; this value judgment is not explicitly examined, argued for, or qualified anywhere in the passage; it is treated as an obvious premise rather than a contested claim

C) The warning has no underlying assumption; it is a purely empirical observation about predicted ecological effects with no evaluative dimension

D) The assumption is explicitly stated in paragraph one, where scientists describe the plastisphere as having "inherent ecological value"

SECTION B — CROSS-PARAGRAPH & DUAL-PASSAGE SYNTHESIS (2 pts each)

Questions 9–14: Connect ideas across paragraphs within and between passages. Evaluate arguments using combined evidence.

9. [Cross-Paragraph Connection] Passage A describes toxic chemicals building up through bioaccumulation. Passage B describes invasive species traveling via plastic rafting to ecosystems worldwide. What combined inference can you draw about the geographic reach of ocean plastic's toxicity?

DOK 3 · CRM C-3

▸ Connect bioaccumulation from Passage A with plastic rafting in Passage B.

A) Bioaccumulation and plastic rafting operate in completely separate ecosystems and therefore cannot be combined into a single inference

B) Because plastic rafting spreads microplastic fragments globally, the toxic chemicals embedded in those fragments—and the bioaccumulation they trigger—are also spreading globally, meaning that pollution generated in one region can contaminate food chains in distant ecosystems that have no direct connection to the original pollution source

C) Plastic rafting actually reduces the toxicity of bioaccumulation by diluting toxic chemicals across a wider ocean area

D) The geographic reach of bioaccumulation is limited to the areas where fish are harvested commercially, which is separate from the routes followed by plastic-rafting organisms

10. [Cross-Paragraph Connection] Passage A predicts more plastic than fish by 2050. Passage B states that plastisphere communities grew over "decades." What new inference emerges from combining these two facts?

DOK 3 · CRM C-3

▸ Synthesize 2050 prediction with plastisphere growth trajectory.

A) By 2050 the plastisphere will be larger than it is today, which means cleanup efforts attempted at that date will face an even more complex ecological disruption problem than they would face today—creating a compounding dilemma in which waiting makes both the plastic problem and the cleanup problem progressively worse simultaneously

B) The plastisphere will have grown large enough by 2050 that its plastic-eating bacteria will have solved the accumulation problem without human intervention

C) The two facts are independent and cannot be combined because plastic production and plastisphere growth follow different timescales

D) By 2050 the plastisphere will have replaced traditional marine ecosystems as the dominant biological community in the ocean

11. [Evaluative Synthesis] Passage A implicitly argues that reducing ocean plastic is urgently needed. Does Passage B support, complicate, or refute this position? Identify the BEST characterization with a specific reason.

DOK 4 · CRM D-4

▸ DOK 4: Evaluate whether Passage B complicates Passage A's implicit argument.

A) Passage B fully supports the urgency of cleanup by providing additional evidence of plastic's harmful effects on microorganisms

B) Passage B significantly complicates without refuting the position: it validates that plastic is harmful (supporting cleanup urgency) while introducing evidence that the method of cleanup—especially microplastic removal—carries its own ecological risks, meaning the question is no longer simply "should we clean up?" but "how do we clean up without causing additional harm?"

C) Passage B directly refutes Passage A's implicit argument by demonstrating that plastic ecosystems now provide ecological benefits that outweigh the harm of the original pollution

D) The two passages cannot be evaluated in relation to each other because they address different scales of the problem

12. [Dual-Passage Synthesis] Both passages describe ocean plastic as a scientific and ecological problem. What topic does neither passage address, and what can you infer about their shared perspective from this omission?

DOK 3 · CRM C-3

▸ Identify the shared gap across both passages.

A) Neither passage addresses the history of plastic invention, implying both authors believe historical context is irrelevant to solving current problems

B) Neither passage addresses the economic incentives that drive plastic production—the corporations that profit from it, the political systems that permit it, or the consumer cultures that sustain it—implying both authors frame ocean plastic as a problem to be solved through science and ecological management rather than through economic regulation, legal accountability, or political transformation

C) Neither passage addresses the impact of ocean plastic on human health through seafood consumption, implying both authors are primarily concerned with wildlife rather than human welfare

D) Neither passage addresses international agreements about ocean pollution, implying both authors believe such agreements are ineffective

13. [Cross-Paragraph Connection] Passage A states that plastic production in 2020 was 367 million metric tons. Passage B states that plastisphere communities have colonized plastic over "decades." What inference can you draw about the relationship between the scale of production and the complexity of the plastisphere?

DOK 3 · CRM C-3

▸ Connect specific production data with plastisphere colonization logic.

A) The 367 million metric ton figure means that only a small fraction of ocean plastic has been colonized by the plastisphere, because the quantity is too large for microorganisms to fully occupy

B) Because plastic has been entering the ocean in increasing quantities over decades, and because the plastisphere colonizes available plastic surfaces, a larger volume of plastic means a larger and more established plastisphere—meaning the ecological complexity of the system that would be disrupted by cleanup is growing in proportion to the accumulation problem itself

C) The high production volume proves that the plastisphere is primarily composed of recently introduced plastic from the 2020 production cycle

D) The two facts cannot be logically connected because one refers to production and the other to colonization, which are separate processes

14. [Evaluative Synthesis] Based on both passages, evaluate whether plastic-eating bacteria constitute a sufficient solution to the ocean plastic crisis. What specific evidence from EACH passage limits the bacteria's adequacy as a complete answer?

DOK 4 · CRM D-4

▸ DOK 4: Evaluate the sufficiency of the plastic-eating bacteria solution across both passages.

A) Plastic-eating bacteria are sufficient because Passage B explicitly states they can break down plastic and Passage A confirms that ocean cleanup is urgently needed

B) The bacteria are insufficient as a complete solution: Passage A shows that plastic production of 367+ million metric tons per year continues to increase, meaning bacteria would need to outpace accelerating input—not just address existing accumulation; Passage B itself cautions the bacteria would take "decades" and could have "unforeseen ecological effects"; neither passage addresses who would fund, deploy, and regulate a global bacterial intervention; and neither addresses whether bacteria could break down all plastic types or address already-bioaccumulated toxins in animal bodies

C) The bacteria are a sufficient solution only if combined with a global ban on new plastic production, which neither passage proposes

D) The adequacy of the bacteria cannot be evaluated from either passage because neither provides sufficient technical detail about how the breakdown process works

SECTION C — PREDICTION & PROJECTION (2 pts each)

Questions 15–18: Use the logic and evidence of both passages to predict likely outcomes, policy implications, and future developments.

15. [Prediction / Projection] A marine biologist concludes after reading both passages: "We cannot effectively clean up the ocean without first reducing plastic production." Is this conclusion logically supported by the combined evidence of both passages?

DOK 3 · CRM C-3

▸ Predict outcome of inaction using both passages.

A) No—both passages suggest cleanup and production reduction are independent problems that can be addressed separately

B) Yes—Passage A shows production is accelerating faster than cleanup could proceed, and Passage B shows cleanup itself generates new ecological risks; together they imply that cleaning up while production continues is like bailing a sinking boat without plugging the hole—the rate of accumulation would outpace any remediation effort while introducing new disruptions

C) The conclusion is supported only by Passage A; Passage B does not address the relationship between production and cleanup effectiveness

D) The conclusion overstates the evidence; both passages argue only that the problem is severe, not that production reduction is a prerequisite to cleanup

16. [Prediction / Projection] Scientists deploy a machine that removes all microplastics from a large ocean region in one month. Based on BOTH passages, what is the MOST likely significant unintended consequence?

DOK 3 · CRM C-3

▸ Predict unintended consequence of a new cleanup technology.

A) The machine would accelerate fish population recovery by immediately removing the plastic threatening their food supply

B) The machine would destroy the established plastisphere communities living on those microplastics—eliminating complex microbial food webs, potentially releasing invasive organisms into open water without their plastic hosts, and disrupting the ecological relationships that have developed over decades

C) The machine would have no ecological effect because microplastics are too small to support significant biological communities

D) The machine would trigger a rapid increase in plastic production as industries replace the removed material with new plastic

17. [Prediction / Projection] Based on the evidence in both passages, which policy approach would be MOST consistent with addressing the full complexity of the ocean plastic problem?

DOK 3 · CRM C-3

▸ Predict most effective policy based on both passages.

A) Deploy plastic-eating bacteria immediately at maximum scale before any other intervention is attempted

B) A coordinated strategy combining strict upstream production limits with staged, ecologically sensitive cleanup protocols that account for plastisphere disruption, invasive species management, and bioaccumulation—rather than treating any single intervention as adequate

C) Focus all resources on physically removing the Great Pacific Garbage Patch before addressing microplastics, which are too diffuse to address practically

D) Declare a ten-year scientific moratorium to fully study the plastisphere before any cleanup efforts are permitted

18. [Prediction / Projection] Based on what BOTH passages leave unanswered, what topic would be most essential for a third passage to address in order to complete the picture of the ocean plastic crisis?

DOK 3 · CRM C-3

▸ Predict what a third passage would need to address.

A) A detailed explanation of how the Great Pacific Garbage Patch was first discovered by oceanographers

B) The economic, political, and corporate systems that drive ongoing plastic production and prevent effective regulation—since both passages treat the crisis scientifically while leaving entirely unaddressed the human incentive structures that generate and perpetuate it

C) A comprehensive catalogue of all marine species affected by plastic ingestion and bioaccumulation

D) A scientific explanation of how plastic-eating bacteria evolved their plastic-degrading enzymes

SECTION D — SHORT ANSWER (10 pts each)

DOK 3–4 | CRM C-3 / D-4 | Complete sentences and evidence from BOTH passages required.

19. [Cross-Passage Inference — Analysis] Passage A describes bioaccumulation of toxic chemicals through the food chain, while Passage B describes invasive species traveling via plastic rafting to new ecosystems. Drawing on BOTH passages, construct a specific inference about how these two processes—bioaccumulation and plastic rafting—might interact to create a threat more serious than either creates alone. You may not simply summarize each passage; you must construct a new conclusion from their combined evidence. (DOK 3 | CRM C-3)

DOK 3 · CRM C-3

20. [Evaluative Synthesis] Both passages present different categories of harm caused by ocean plastic. Passage A focuses on harm to larger organisms (birds, turtles, fish) through ingestion and poisoning. Passage B focuses on harm at the microbial and ecosystem level (plastisphere disruption, invasive species spread, bacterial effects). Evaluate: which category of harm is MORE fundamental—harm to large organisms or harm to microbial and ecosystem processes? Construct a specific argument using evidence from BOTH passages, and explain what your answer implies about how we should prioritize ocean plastic solutions. (DOK 4 | CRM D-4)

DOK 4 · CRM D-4

SECTION E — EXTENDED SYNTHESIS ESSAY (20 pts)

DOK Level 4 | CRM D-4 | Minimum 10 sentences. Draw on BOTH passages. Construct original inferences—do not simply summarize.

21. [Full Synthesis — Extended Response] Full Synthesis: Both passages present ocean plastic as a problem that becomes MORE complex, not less, the more carefully it is examined. In a well-organized extended response drawing on evidence from BOTH passages: (1) construct a single unified inference about what the combined evidence of both passages reveals that neither reveals alone; (2) identify the TWO most important facts—one from each passage—that you would need a policymaker to understand before designing any ocean plastic solution; (3) evaluate which type of harm described across both passages is hardest to reverse, and explain what evidence leads you to this conclusion; and (4) construct your own inference about what the existence of the plastisphere reveals about the long-term relationship between human technological civilization and natural systems—an inference that goes beyond anything either passage states explicitly.

DOK 4 · CRM D-4

SECTION F — DETECTIVE JOURNAL (4 pts each)

DOK 2–3 | CRM B-2 / C-3 | The detective journal trains the habit of inference. For each prompt, write 2–4 sentences explaining your reasoning. Show your "clues → conclusion" thinking.

Clue File 1: Passage A states that plastic "does not dissolve or go away." Based on this fact alone, construct a specific inference about what the ocean will look like in 200 years if production continues.

Clue File 2: Passage B states that plastic-eating bacteria could have "unforeseen ecological effects." Using only evidence already in Passage B, infer TWO specific effects that might be "unforeseen."

Clue File 3: Both passages describe a problem that gets harder to solve the longer it continues. What general principle about complex environmental problems can you infer from this shared pattern?
