This question tests identifying text structures in informational texts (CCSS.RI.4.5), specifically recognizing cause and effect structure. The passage uses cause and effect structure, which explains what happened and why. Signal words like 'Because,' 'When,' 'As,' 'As a result,' and 'Therefore' indicate this structure. The passage is organized to show how the Moon's orbit (cause) creates different phases we see from Earth (effect), and how the Moon's position relative to Earth and Sun (cause) determines which phase is visible (effect). Choice A is correct because it accurately identifies the primary structure—the passage explains what causes the Moon's phases to occur. Choice B is incorrect because while the passage mentions the Moon's movement over time, it doesn't organize information chronologically but rather focuses on explaining why phases happen. To help students recognize text structures: Teach the four main informational structures—(1) Chronology/Sequence: events in time order (signal words: first, next, then, after, before, finally); (2) Comparison/Contrast: similarities and differences (signal words: similar, different, both, unlike, however, while); (3) Cause and Effect: what happened and why (signal words: because, so, as a result, therefore, since, causes, leads to); (4) Problem and Solution: issue and resolution (signal words: problem, solution, solve, question, answer). Create anchor charts with signal words for each structure.

This question tests identifying text structures in informational texts (CCSS.RI.4.5), specifically recognizing cause and effect structure. The passage uses cause and effect structure, which explains what happened and why. Signal words like 'because of,' 'as a result,' and 'therefore' indicate this structure. The passage is organized to show how friction (cause) leads to various effects: balls slowing down, the need for oil on bike chains, and wear on surfaces. Choice B is correct because it accurately identifies the primary structure—the passage explains what friction causes to happen in different situations. Choice D is incorrect because while the passage mentions a solution (adding oil), this is just one example within the larger cause-effect framework, not the main organizational structure.

This question tests identifying text structures in informational texts (CCSS.RI.4.5), specifically recognizing comparison/contrast structure. The passage uses comparison/contrast structure, which shows similarities and differences between two things. Signal words like 'both,' 'different,' 'while,' 'in contrast,' 'whereas,' and 'however' indicate this structure. The passage is organized to systematically compare deserts and rainforests—first their rainfall, then their plants, and finally noting that animals in both need food and shelter. Choice C is correct because it accurately identifies the primary structure—the entire passage is devoted to comparing and contrasting these two habitats. Choice A is incorrect because while the passage mentions effects (like plants storing water), these are details within the comparison, not the main organizational structure.

Watch for: confusing content (what text is about) with structure (how text is organized), identifying minor structure instead of primary one, seeing one signal word and assuming structure without checking overall organization.

This question tests identifying text structures in informational texts (CCSS.RI.4.5), specifically recognizing chronology/sequence structure. The passage uses chronology/sequence structure, which shows events in time order. Signal words like 'first,' 'next,' 'then,' 'after that,' and 'finally' indicate this structure. The passage is organized to follow the butterfly life cycle in sequential order: egg → caterpillar → chrysalis → butterfly → flying. Choice A is correct because it accurately describes how the text is organized—the passage presents the stages of butterfly development in the exact order they occur. Choice D is incorrect because while transformation happens (caterpillar to butterfly), the passage doesn't focus on cause-effect relationships but rather on the sequence of stages.

This question tests identifying text structures in informational texts (CCSS.RI.4.5), specifically recognizing cause and effect relationships. The passage uses cause and effect structure, which explains what happened and why. Signal words like 'when,' 'because,' 'as a result,' and 'therefore' indicate this structure. The passage is organized to show how bare soil (cause) leads to erosion moving soil into rivers (effect), and how planting cover crops (cause) protects the soil (effect). Choice A is correct because it accurately identifies the primary cause-effect relationship in the passage—bare soil causes erosion which moves soil into rivers. Choice B is incorrect because it reverses the cause-effect relationship—muddy rivers are an effect of erosion, not a cause of plants growing stronger roots.
