This question tests CCSS.RI.6.5: analyzing how a particular sentence, paragraph, chapter, or section fits into the overall structure of an informational text and contributes to the development of ideas by examining structure and function of text parts. Informational texts are organized using specific structures to present ideas clearly: Cause and Effect (shows reasons and results using 'because,' 'as a result,' 'therefore'), Compare and Contrast (examines similarities/differences using 'similarly,' 'however,' 'in contrast'), Chronological/Sequence (presents events or steps in order using 'first,' 'next,' 'finally'), Problem and Solution (identifies problem then proposes solutions), Description (main idea supported by details). Within these structures, individual sentences and paragraphs serve specific functions: Topic sentence (states main idea), Supporting details (provide evidence, examples, facts), Transitions (connect ideas showing relationships), Introduction (opens and sets up topic), Conclusion (wraps up and summarizes), Examples (illustrate with specific instances). Understanding how each part contributes to the whole helps readers comprehend how information is organized and ideas are developed. This passage uses a cause-effect structure. The passage explains how replacing grass with pavement causes flooding and pollution. The second sentence in question, beginning with 'As a result,' serves the function of stating an effect that results from the cause mentioned in sentence 1. Choice B is correct because it accurately identifies how sentence 2 contributes to the cause-effect structure. This sentence states the effect ('rainwater runs off quickly and can flood streets') that results from the cause (replacing grass with pavement) mentioned in the previous sentence, which develops the cause-effect structure of the passage. The transition phrase 'As a result' explicitly signals this cause-effect relationship. Without this sentence, the cause-effect relationship would be unclear—readers wouldn't understand what happens when grass is replaced with pavement. Understanding this part's function helps readers see how the author organized information to show relationships between actions and consequences. Choice A is incorrect because it misidentifies the sentence's function—the sentence doesn't provide a solution but rather describes a negative effect or consequence. The passage is explaining problems caused by pavement, not solving them. This is a cause-effect structure showing consequences, not a problem-solution structure offering fixes. Analyzing contribution requires looking beyond content to understand function—how the part works within the whole to organize information and develop ideas. To help students analyze how text parts contribute: (1) Teach TEXT STRUCTURES explicitly with signal words - CAUSE and EFFECT: Cause (reason why) → Effect (result/consequence). Signal words: because, since, due to, as a result, therefore, consequently, so, leads to, causes. Example: 'Climate change is caused by greenhouse gases [CAUSE]. As a result, temperatures rise [EFFECT].' How parts contribute: Cause sentences identify reasons; effect sentences show results; transitions like 'as a result' connect cause to effect. (2) Practice with GRAPHIC ORGANIZERS - Cause-Effect chart (causes on left, effects on right, arrows connecting). Example teaching sequence: Read passage → Identify overall structure (What pattern organizes this? Cause-effect? Compare? Sequence?) → Find signal words (therefore, however, first, etc.) → Locate specific sentence/paragraph → Determine its function (Does it introduce topic? Support main idea? Show cause? Provide transition?) → Explain contribution (How does this part fit into whole structure? How does it develop ideas?).

This question tests CCSS.RI.6.5: analyzing how a particular sentence, paragraph, chapter, or section fits into the overall structure of an informational text and contributes to the development of ideas by examining structure and function of text parts. Informational texts are organized using specific structures to present ideas clearly: Cause and Effect (shows reasons and results using 'because,' 'as a result,' 'therefore'), Compare and Contrast (examines similarities/differences using 'similarly,' 'however,' 'in contrast'), Chronological/Sequence (presents events or steps in order using 'first,' 'next,' 'finally'), Problem and Solution (identifies problem then proposes solutions), Description (main idea supported by details). Within these structures, individual sentences and paragraphs serve specific functions: Topic sentence (states main idea), Supporting details (provide evidence, examples, facts), Transitions (connect ideas showing relationships), Introduction (opens and sets up topic), Conclusion (wraps up and summarizes), Examples (illustrate with specific instances). Understanding how each part contributes to the whole helps readers comprehend how information is organized and ideas are developed. This passage uses a problem-solution structure. The passage identifies the problem of food waste in school cafeterias and then presents a solution. The third sentence in question, beginning with 'To address this problem,' serves the function of providing a solution to the problem described in the first two sentences. Choice A is correct because it accurately identifies how sentence 3 contributes to the problem-solution structure. This sentence provides a solution ('share tables where students can leave extra sealed items for others') that directly responds to the problem of wasted food and money described in sentences 1 and 2, which develops the problem-solution structure of the passage. The phrase 'To address this problem' explicitly signals the shift from problem to solution. Without this sentence, the passage would only describe problems without offering any way to fix them. Understanding this part's function helps readers see how the author organized information to not just identify issues but also propose practical solutions. Choice B is incorrect because it misidentifies the sentence's function—the sentence doesn't list more problems or effects but rather provides a solution. The phrase 'To address this problem' clearly indicates this is a solution, not another problem. The sentence describes a positive action (share tables) to fix the issue, not additional negative effects of food waste. This maintains the problem-solution structure by offering a fix, not expanding the problem. Analyzing contribution requires looking beyond content to understand function—how the part works within the whole to organize information and develop ideas. To help students analyze how text parts contribute: (1) Teach TEXT STRUCTURES explicitly with signal words - PROBLEM and SOLUTION: Identifies problem, proposes solution(s). Signal words: problem, issue, to solve, to address, solution, one way to fix. Example: 'Pollution threatens oceans [PROBLEM]. To address this, communities reduce plastics [SOLUTION].' How parts contribute: Early sentences state problem; later sentences propose solutions. (2) Practice with GRAPHIC ORGANIZERS - Problem-Solution chart with problem on left, solutions on right. Draw arrows from problem to each solution. Example teaching sequence: Read passage → Identify sentences describing problems (negative situations) → Find signal words like 'to address,' 'to solve' → Locate sentences offering solutions (positive actions) → Determine if specific sentence states problem or solution → Explain how solution responds to specific problem.

This question tests CCSS.RI.6.5: analyzing how a particular sentence, paragraph, chapter, or section fits into the overall structure of an informational text and contributes to the development of ideas by examining structure and function of text parts. Informational texts are organized using specific structures to present ideas clearly: Cause and Effect (shows reasons and results using 'because,' 'as a result,' 'therefore'), Compare and Contrast (examines similarities/differences using 'similarly,' 'however,' 'in contrast'), Chronological/Sequence (presents events or steps in order using 'first,' 'next,' 'finally'), Problem and Solution (identifies problem then proposes solutions), Description (main idea supported by details). Within these structures, individual sentences and paragraphs serve specific functions: Topic sentence (states main idea), Supporting details (provide evidence, examples, facts), Transitions (connect ideas showing relationships), Introduction (opens and sets up topic), Conclusion (wraps up and summarizes), Examples (illustrate with specific instances). Understanding how each part contributes to the whole helps readers comprehend how information is organized and ideas are developed. This passage uses a compare-contrast structure. The passage compares two types of renewable energy—solar panels and wind turbines. The third sentence in question, beginning with 'Both,' serves the function of stating a similarity between the two energy sources after presenting their differences. Choice A is correct because it accurately identifies how sentence 3 contributes to the compare-contrast structure. This sentence states a similarity ('Both energy sources produce electricity without burning fuel') that balances the differences described in the first two sentences, which develops the compare-contrast structure of the passage. The word 'Both' signals this shift from differences to similarities. Without this sentence, the passage would only show differences without acknowledging what solar and wind power have in common. Understanding this part's function helps readers see how the author organized information to show both differences and similarities between the two energy sources. Choice C is incorrect because it misidentifies both the text structure and the sentence's function. The passage is not about causes of air pollution—it's comparing two clean energy sources. The sentence doesn't explain any cause; it identifies a shared characteristic (similarity) between solar and wind power. This is a compare-contrast structure showing similarities and differences, not a cause-effect structure explaining pollution. Analyzing contribution requires looking beyond content to understand function—how the part works within the whole to organize information and develop ideas. To help students analyze how text parts contribute: (1) Teach TEXT STRUCTURES explicitly with signal words - COMPARE and CONTRAST: Shows similarities and/or differences between two or more things. Signal words: similarly, likewise, both, in contrast, however, while, whereas, different from, unlike. Example: 'Deciduous trees lose leaves [THING 1], while evergreens keep needles [THING 2]. Both produce oxygen [SIMILARITY].' How parts contribute: Sentences describe each item; transition words signal switch between items or from differences to similarities. (2) Use ANNOTATION - Circle transition words like 'both,' 'however,' 'while.' Mark similarities with = signs, differences with ≠ signs. Label which sentences describe Thing 1, Thing 2, or both. Example teaching sequence: Identify what's being compared → Find sentences about each item → Look for similarity/difference signal words → Determine if sentence shows similarity or difference → Explain how it balances or develops the comparison.

Informational texts are organized using specific structures to present ideas clearly: Cause and Effect (shows reasons and results using 'because,' 'as a result,' 'therefore'), Compare and Contrast (examines similarities/differences using 'similarly,' 'however,' 'in contrast'), Chronological/Sequence (presents events or steps in order using 'first,' 'next,' 'finally'), Problem and Solution (identifies problem then proposes solutions), Description (main idea supported by details). Within these structures, individual sentences and paragraphs serve specific functions: Topic sentence (states main idea), Supporting details (provide evidence, examples, facts), Transitions (connect ideas showing relationships), Introduction (opens and sets up topic), Conclusion (wraps up and summarizes), Examples (illustrate with specific instances). Understanding how each part contributes to the whole helps readers comprehend how information is organized and ideas are developed. This passage uses a compare-contrast structure. The passage compares two renewable energy systems: solar panels and wind turbines. The first two sentences highlight differences (how they work, when they work), while the third sentence with 'Both' serves the function of showing a similarity between the two systems. Choice A is correct because it accurately identifies how sentence 3 contributes to the compare-contrast structure. This sentence provides a similarity (both reduce pollution) that balances the earlier differences, which develops the compare-contrast structure by showing not just how the systems differ but also what they have in common. The contribution is essential: without this sentence showing similarity, the passage would only contrast the systems without acknowledging their shared benefit. Understanding this part's function helps readers see how the author organized information to present a balanced comparison. Choice C is incorrect because it misidentifies the sentence's function—while the sentence does mention pollution, it's not explaining a cause but rather identifying a shared characteristic of both energy systems. The sentence clearly connects to both solar panels and wind turbines mentioned earlier, using 'Both' to signal this similarity. Analyzing contribution requires looking beyond content to understand function—how the part works within the whole to organize information and develop ideas. To help students analyze how text parts contribute: (1) Teach TEXT STRUCTURES explicitly with signal words - CAUSE and EFFECT: Cause (reason why) → Effect (result/consequence). Signal words: because, since, due to, as a result, therefore, consequently, so, leads to, causes. Example: 'Climate change is caused by greenhouse gases [CAUSE]. As a result, temperatures rise [EFFECT].' How parts contribute: Cause sentences identify reasons; effect sentences show results; transitions like 'as a result' connect cause to effect. COMPARE and CONTRAST: Shows similarities and/or differences between two or more things. Signal words: similarly, likewise, both, in contrast, however, while, whereas, different from, unlike. Example: 'Deciduous trees lose leaves [THING 1], while evergreens keep needles [THING 2]. Both produce oxygen [SIMILARITY].' How parts contribute: Sentences describe each item; transition words signal switch between items or from differences to similarities. CHRONOLOGICAL/SEQUENCE: Events or steps in time order. Signal words: first, next, then, finally, before, after, during, meanwhile. Example: 'First, the caterpillar hatches. Next, it grows. Then, it forms chrysalis. Finally, it emerges as butterfly.' How parts contribute: Each sentence is a step; sequence words organize order. PROBLEM and SOLUTION: Identifies problem, proposes solution(s). Signal words: problem, issue, to solve, to address, solution, one way to fix. Example: 'Pollution threatens oceans [PROBLEM]. To address this, communities reduce plastics [SOLUTION].' How parts contribute: Early sentences state problem; later sentences propose solutions. DESCRIPTION: Main idea supported by details. Signal words: for example, such as, characteristics include, features are. Example: 'Rainforests are biodiverse [MAIN IDEA]. They contain thousands of plants [DETAIL 1] and countless animals [DETAIL 2].' How parts contribute: Topic sentence states main idea; following sentences provide supporting details. (2) Teach sentence/paragraph FUNCTIONS - Introduction: Opens text, introduces topic, may state thesis. Topic Sentence: States main idea of paragraph (often first sentence). Supporting Detail: Provides evidence, examples, facts to support main idea. Example: Illustrates concept with specific instance ('For example,'). Transition: Connects ideas, shows relationships ('However,' 'Therefore,' 'In addition'). Explanation: Clarifies or elaborates on idea. Conclusion: Summarizes, wraps up, may state significance. (3) ANALYZE systematically - Step 1: Identify overall text structure (cause-effect, compare-contrast, sequence, problem-solution, description). Step 2: Locate the specific sentence/paragraph to analyze. Step 3: Determine its function (introduction, topic sentence, supporting detail, transition, example, explanation, conclusion). Step 4: Explain how it contributes to structure or develops ideas. Step 5: Ask: What would be missing if this part were removed? (4) Practice with GRAPHIC ORGANIZERS - Cause-Effect chart (causes on left, effects on right, arrows connecting). Compare-Contrast Venn diagram or T-chart. Sequence timeline or flowchart. Problem-Solution chart (problem | solutions). Main Idea web (center = main idea, spokes = supporting details). (5) Use ANNOTATION - Number sentences. Circle transition words. Underline topic sentences. Mark cause/effect, similarities/differences. Label functions (introduction, detail, conclusion). Example teaching sequence: Read passage → Identify overall structure (What pattern organizes this? Cause-effect? Compare? Sequence?) → Find signal words (therefore, however, first, etc.) → Locate specific sentence/paragraph → Determine its function (Does it introduce topic? Support main idea? Show cause? Provide transition?) → Explain contribution (How does this part fit into whole structure? How does it develop ideas?).

Understanding how each part contributes to the whole helps readers comprehend how information is organized and ideas are developed. This passage uses a problem-solution structure. The passage identifies a problem (lack of trees causing hot sidewalks) and its effects (difficulty walking/playing outside), then presents a solution (planting shade trees). Sentence 3, beginning with 'One solution is,' serves the function of providing the solution component that completes the problem-solution structure. Choice A is correct because it accurately identifies how removing sentence 3 would affect the passage structure. Without sentence 3, the passage would lose the solution component and mostly describe the problem (lack of trees) and its effects (hot sidewalks, difficulty being outside), leaving the problem-solution structure incomplete. The phrase 'One solution is' clearly signals this sentence's function as the solution element. Without this solution, readers would know about the problem but not how to address it, fundamentally changing the passage from problem-solution to merely problem description. Understanding this contribution helps readers see how problem-solution texts require both components—problem and solution—to fulfill their structural purpose of not just identifying issues but also proposing ways to address them. Choice D is incorrect because it misunderstands what would remain if sentence 3 were removed. Without sentence 3, there would be no solution presented at all, and therefore no conclusion that summarizes any solution. The passage would end with sentence 2 describing the effects of the problem (difficulty walking/playing), which is not a conclusion but rather an elaboration of the problem. Removing the solution sentence eliminates the resolution entirely, not just affecting but completely removing any conclusive solution element. Analyzing contribution requires understanding that in problem-solution structures, the solution sentence is essential—without it, the structure becomes incomplete. To help students analyze how text parts contribute: (1) Teach TEXT STRUCTURES explicitly with signal words - CAUSE and EFFECT: Cause (reason why) → Effect (result/consequence). Signal words: because, since, due to, as a result, therefore, consequently, so, leads to, causes. Example: 'Climate change is caused by greenhouse gases [CAUSE]. As a result, temperatures rise [EFFECT].' How parts contribute: Cause sentences identify reasons; effect sentences show results; transitions like 'as a result' connect cause to effect. COMPARE and CONTRAST: Shows similarities and/or differences between two or more things. Signal words: similarly, likewise, both, in contrast, however, while, whereas, different from, unlike. Example: 'Deciduous trees lose leaves [THING 1], while evergreens keep needles [THING 2]. Both produce oxygen [SIMILARITY].' How parts contribute: Sentences describe each item; transition words signal switch between items or from differences to similarities. CHRONOLOGICAL/SEQUENCE: Events or steps in time order. Signal words: first, next, then, finally, before, after, during, meanwhile. Example: 'First, the caterpillar hatches. Next, it grows. Then, it forms chrysalis. Finally, it emerges as butterfly.' How parts contribute: Each sentence is a step; sequence words organize order. PROBLEM and SOLUTION: Identifies problem, proposes solution(s). Signal words: problem, issue, to solve, to address, solution, one way to fix. Example: 'Pollution threatens oceans [PROBLEM]. To address this, communities reduce plastics [SOLUTION].' How parts contribute: Early sentences state problem; later sentences propose solutions. DESCRIPTION: Main idea supported by details. Signal words: for example, such as, characteristics include, features are. Example: 'Rainforests are biodiverse [MAIN IDEA]. They contain thousands of plants [DETAIL 1] and countless animals [DETAIL 2].' How parts contribute: Topic sentence states main idea; following sentences provide supporting details. (2) Teach sentence/paragraph FUNCTIONS - Introduction: Opens text, introduces topic, may state thesis. Topic Sentence: States main idea of paragraph (often first sentence). Supporting Detail: Provides evidence, examples, facts to support main idea. Example: Illustrates concept with specific instance ('For example,'). Transition: Connects ideas, shows relationships ('However,' 'Therefore,' 'In addition'). Explanation: Clarifies or elaborates on idea. Conclusion: Summarizes, wraps up, may state significance. (3) ANALYZE systematically - Step 1: Identify overall text structure (cause-effect, compare-contrast, sequence, problem-solution, description). Step 2: Locate the specific sentence/paragraph to analyze. Step 3: Determine its function (introduction, topic sentence, supporting detail, transition, example, explanation, conclusion). Step 4: Explain how it contributes to structure or develops ideas. Step 5: Ask: What would be missing if this part were removed? (4) Practice with GRAPHIC ORGANIZERS - Cause-Effect chart (causes on left, effects on right, arrows connecting). Compare-Contrast Venn diagram or T-chart. Sequence timeline or flowchart.

This question tests CCSS.RI.6.5: analyzing how a particular sentence, paragraph, chapter, or section fits into the overall structure of an informational text and contributes to the development of ideas by examining structure and function of text parts. Informational texts are organized using specific structures to present ideas clearly: Cause and Effect (shows reasons and results using 'because,' 'as a result,' 'therefore'), Compare and Contrast (examines similarities/differences using 'similarly,' 'however,' 'in contrast'), Chronological/Sequence (presents events or steps in order using 'first,' 'next,' 'finally'), Problem and Solution (identifies problem then proposes solutions), Description (main idea supported by details). Within these structures, individual sentences and paragraphs serve specific functions: Topic sentence (states main idea), Supporting details (provide evidence, examples, facts), Transitions (connect ideas showing relationships), Introduction (opens and sets up topic), Conclusion (wraps up and summarizes), Examples (illustrate with specific instances). Understanding how each part contributes to the whole helps readers comprehend how information is organized and ideas are developed. This passage uses a chronological/sequence structure. The passage describes events in sequence: the steps Jamal follows to plant a seed. The third sentence with 'Then' serves the function of providing the third step in the chronological process. Choice B is correct because it accurately identifies how sentence 3 contributes to the sequence structure. This sentence provides the third step (planting and watering) that follows logically after rinsing the jar and filling it with soil, which develops the chronological structure of the passage. The contribution is crucial: without this sentence, the sequence would jump from filling the jar with soil directly to placing it near sunlight, missing the essential planting step. Understanding this part's function helps readers see how the author organized information to guide understanding of a process. Choice A is incorrect because it misidentifies the sentence's function—the sentence doesn't give a concluding opinion but rather provides a necessary step in the middle of the sequence. The word 'Then' clearly signals this is a continuing step, not a conclusion, and the content (planting and watering) is an action step, not an opinion. Analyzing contribution requires looking beyond content to understand function—how the part works within the whole to organize information and develop ideas. To help students analyze how text parts contribute: (1) Teach TEXT STRUCTURES explicitly with signal words - CAUSE and EFFECT: Cause (reason why) → Effect (result/consequence).

(2) Teach sentence/paragraph FUNCTIONS - Introduction: Opens text, introduces topic, may state thesis. Topic Sentence: States main idea of paragraph (often first sentence). Supporting Detail: Provides evidence, examples, facts to support main idea. Example: Illustrates concept with specific instance ('For example,'). Transition: Connects ideas, shows relationships ('However,' 'Therefore,' 'In addition'). Explanation: Clarifies or elaborates on idea. Conclusion: Summarizes, wraps up, may state significance.

Understanding how each part contributes to the whole helps readers comprehend how information is organized and ideas are developed. This passage uses a compare-contrast structure. The passage compares two types of computers—laptops and desktops—examining their different characteristics. The word 'However' in sentence 3 serves the function of transitioning from discussing a desktop advantage to presenting a contrasting laptop advantage. Choice B is correct because it accurately identifies how 'However' contributes to the compare-contrast structure. This transition word signals a shift from discussing desktop advantages (easier to upgrade) to contrasting laptop advantages (better for students who travel), which develops the comparison by showing both sides. Without this transitional 'However,' the shift between contrasting points would be abrupt and the compare-contrast structure would be less clear. Understanding this transition's function helps readers see how the author organized information to present balanced comparisons between the two computer types. Choice A is incorrect because it misidentifies the text structure as cause-and-effect when it's actually compare-contrast. While 'However' can sometimes introduce effects, here it signals contrast between desktop and laptop advantages, not a causal relationship between upgrades and travel. Analyzing contribution requires recognizing the overall structure—this is comparing two things, not showing how one causes another. To help students analyze how text parts contribute: (1) Teach TEXT STRUCTURES explicitly with signal words - CAUSE and EFFECT: Cause (reason why) → Effect (result/consequence). Signal words: because, since, due to, as a result, therefore, consequently, so, leads to, causes. Example: 'Climate change is caused by greenhouse gases [CAUSE]. As a result, temperatures rise [EFFECT].' How parts contribute: Cause sentences identify reasons; effect sentences show results; transitions like 'as a result' connect cause to effect. COMPARE and CONTRAST: Shows similarities and/or differences between two or more things. Signal words: similarly, likewise, both, in contrast, however, while, whereas, different from, unlike. Example: 'Deciduous trees lose leaves [THING 1], while evergreens keep needles [THING 2]. Both produce oxygen [SIMILARITY].' How parts contribute: Sentences describe each item; transition words signal switch between items or from differences to similarities. CHRONOLOGICAL/SEQUENCE: Events or steps in time order. Signal words: first, next, then, finally, before, after, during, meanwhile. Example: 'First, the caterpillar hatches. Next, it grows. Then, it forms chrysalis. Finally, it emerges as butterfly.' How parts contribute: Each sentence is a step; sequence words organize order. PROBLEM and SOLUTION: Identifies problem, proposes solution(s). Signal words: problem, issue, to solve, to address, solution, one way to fix. Example: 'Pollution threatens oceans [PROBLEM]. To address this, communities reduce plastics [SOLUTION].' How parts contribute: Early sentences state problem; later sentences propose solutions. DESCRIPTION: Main idea supported by details. Signal words: for example, such as, characteristics include, features are. Example: 'Rainforests are biodiverse [MAIN IDEA].

This question tests CCSS.RI.6.5: analyzing how a particular sentence, paragraph, chapter, or section fits into the overall structure of an informational text and contributes to the development of ideas by examining structure and function of text parts. Informational texts are organized using specific structures to present ideas clearly: Cause and Effect (shows reasons and results using 'because,' 'as a result,' 'therefore'), Compare and Contrast (examines similarities/differences using 'similarly,' 'however,' 'in contrast'), Chronological/Sequence (presents events or steps in order using 'first,' 'next,' 'finally'), Problem and Solution (identifies problem then proposes solutions), Description (main idea supported by details). Within these structures, individual sentences and paragraphs serve specific functions: Topic sentence (states main idea), Supporting details (provide evidence, examples, facts), Transitions (connect ideas showing relationships), Introduction (opens and sets up topic), Conclusion (wraps up and summarizes), Examples (illustrate with specific instances). Understanding how each part contributes to the whole helps readers comprehend how information is organized and ideas are developed. This passage uses a chronological/sequence structure. The passage describes the steps Maya follows to work with wood in time order: measuring, marking, sawing, and sanding. Sentence 4, beginning with 'Finally,' serves the function of providing the concluding step that completes the woodworking process. Choice A is correct because it accurately identifies how sentence 4 contributes to the sequence structure. This sentence provides the concluding step (sanding the edges smooth) that completes the process in chronological order, signaled by the sequence word 'Finally.' This final step is essential to the sequence structure because it shows the completion of the woodworking process—without it, the sequence would be incomplete, ending abruptly after cutting. The contribution is clear: sentence 4 provides closure to the sequence by showing the finishing touch that makes the wood piece ready for use. Understanding this part's function helps readers see how sequence texts use ordinal words (first, next, then, finally) to organize steps and signal completion. Choice C is incorrect because it misidentifies both the text structure and the sentence's function. The passage uses a sequence structure to show steps in order, not a problem-solution structure. Sentence 4 doesn't explain why edges are rough (a cause) or present a problem and solution; it simply states the final step in the process. The word 'Finally' clearly signals this is the last in a sequence of steps, not an explanation of causes or solutions. Analyzing contribution requires recognizing the overall structure—this is a how-to sequence, not a text explaining problems and their solutions. To help students analyze how text parts contribute: (1) Teach TEXT STRUCTURES explicitly with signal words - CAUSE and EFFECT: Cause (reason why) → Effect (result/consequence). Signal words: because, since, due to, as a result, therefore, consequently, so, leads to, causes. Example: 'Climate change is caused by greenhouse gases [CAUSE]. As a result, temperatures rise [EFFECT].' How parts contribute: Cause sentences identify reasons; effect sentences show results; transitions like 'as a result' connect cause to effect. COMPARE and CONTRAST: Shows similarities and/or differences between two or more things. Signal words: similarly, likewise, both, in contrast, however, while, whereas, different from, unlike. Example: 'Deciduous trees lose leaves [THING 1], while evergreens keep needles [THING 2]. Both produce oxygen [SIMILARITY].' How parts contribute: Sentences describe each item; transition words signal switch between items or from differences to similarities. CHRONOLOGICAL/SEQUENCE: Events or steps in time order. Signal words: first, next, then, finally, before, after, during, meanwhile. Example: 'First, the caterpillar hatches. Next, it grows. Then, it forms chrysalis. Finally, it emerges as butterfly.' How parts contribute: Each sentence is a step; sequence words organize order. PROBLEM and SOLUTION: Identifies problem, proposes solution(s). Signal words: problem, issue, to solve, to address, solution, one way to fix. Example: 'Pollution threatens oceans [PROBLEM]. To address this, communities reduce plastics [SOLUTION].' How parts contribute: Early sentences state problem; later sentences propose solutions. DESCRIPTION: Main idea supported by details. Signal words: for example, such as, characteristics include, features are. Example: 'Rainforests are biodiverse [MAIN IDEA]. They contain thousands of plants [DETAIL 1] and countless animals [DETAIL 2].' How parts contribute: Topic sentence states main idea; following sentences provide supporting details. (2) Teach sentence/paragraph FUNCTIONS - Introduction: Opens text, introduces topic, may state thesis. Topic Sentence: States main idea of paragraph (often first sentence). Supporting Detail: Provides evidence, examples, facts to support main idea. Example: Illustrates concept with specific instance ('For example,'). Transition: Connects ideas, shows relationships ('However,' 'Therefore,' 'In addition'). Explanation: Clarifies or elaborates on idea. Conclusion: Summarizes, wraps up, may state significance. (3) ANALYZE systematically - Step 1: Identify overall text structure (cause-effect, compare-contrast, sequence, problem-solution, description). Step 2: Locate the specific sentence/paragraph to analyze. Step 3: Determine its function (introduction, topic sentence, supporting detail, transition, example, explanation, conclusion). Step 4: Explain how it contributes to structure or develops ideas. Step 5: Ask: What would be missing if this part were removed? (4) Practice with GRAPHIC ORGANIZERS - Cause-Effect chart (causes on left, effects on right, arrows connecting). Compare-Contrast Venn diagram or T-chart. Sequence timeline or flowchart. Problem-Solution chart (problem | solutions). Main Idea web (center = main idea, spokes = supporting details). (5) Use ANNOTATION - Number sentences. Circle transition words. Underline topic sentences. Mark cause/effect, similarities/differences. Label functions (introduction, detail, conclusion). Example teaching sequence: Read passage → Identify overall structure (What pattern organizes this? Cause-effect? Compare? Sequence?) → Find signal words (therefore, however, first, etc.) → Locate specific sentence/paragraph → Determine its function (Does it introduce topic? Support main idea? Show cause? Provide transition?) → Explain contribution (How does this part fit into whole structure? How does it develop ideas?).

This question tests CCSS.RI.6.5: analyzing how a particular sentence, paragraph, chapter, or section fits into the overall structure of an informational text and contributes to the development of ideas by examining structure and function of text parts. Informational texts are organized using specific structures to present ideas clearly: Cause and Effect (shows reasons and results using 'because,' 'as a result,' 'therefore'), Compare and Contrast (examines similarities/differences using 'similarly,' 'however,' 'in contrast'), Chronological/Sequence (presents events or steps in order using 'first,' 'next,' 'finally'), Problem and Solution (identifies problem then proposes solutions), Description (main idea supported by details). Within these structures, individual sentences and paragraphs serve specific functions: Topic sentence (states main idea), Supporting details (provide evidence, examples, facts), Transitions (connect ideas showing relationships), Introduction (opens and sets up topic), Conclusion (wraps up and summarizes), Examples (illustrate with specific instances). Understanding how each part contributes to the whole helps readers comprehend how information is organized and ideas are developed. This passage uses a description structure. The passage presents a main idea about coral reefs and supports it with specific details. The first sentence in question serves the function of stating the main idea that the following sentences will develop with supporting details. Choice B is correct because it accurately identifies how sentence 1 contributes to the description structure. This sentence states the main idea ('Coral reefs are busy underwater communities') that the other sentences develop with specific details about hiding places, wave protection, and food relationships, which establishes the description structure of the passage. As the topic sentence, it introduces what will be described in detail. Without this sentence, the supporting details would lack a unifying main idea. Understanding this part's function helps readers see how the author organized information with a clear main idea followed by supporting evidence. Choice A is incorrect because it reverses the sentence's function—sentence 1 doesn't provide a supporting example but rather states the main idea. The sentence makes a general statement about coral reefs being 'busy underwater communities,' not a specific example about waves and beaches. The following sentences (2, 3, and 4) are the supporting details that prove the main idea, not the other way around. This is a description structure with main idea first, then details. Analyzing contribution requires looking beyond content to understand function—how the part works within the whole to organize information and develop ideas. To help students analyze how text parts contribute: (1) Teach TEXT STRUCTURES explicitly with signal words - DESCRIPTION: Main idea supported by details. Signal words: for example, such as, characteristics include, features are. Example: 'Rainforests are biodiverse [MAIN IDEA]. They contain thousands of plants [DETAIL 1] and countless animals [DETAIL 2].' How parts contribute: Topic sentence states main idea; following sentences provide supporting details. (2) Teach sentence/paragraph FUNCTIONS - Topic Sentence: States main idea of paragraph (often first sentence). Supporting Detail: Provides evidence, examples, facts to support main idea. (3) Practice with GRAPHIC ORGANIZERS - Main Idea web with center = main idea, spokes = supporting details. Example teaching sequence: Read passage → Find the broadest statement (main idea) → Identify specific details that support it → Determine if sentence states main idea or provides detail → Explain how details develop and prove the main idea.

This question tests CCSS.RI.6.5: analyzing how a particular sentence, paragraph, chapter, or section fits into the overall structure of an informational text and contributes to the development of ideas by examining structure and function of text parts. Informational texts are organized using specific structures to present ideas clearly: Cause and Effect (shows reasons and results using 'because,' 'as a result,' 'therefore'), Compare and Contrast (examines similarities/differences using 'similarly,' 'however,' 'in contrast'), Chronological/Sequence (presents events or steps in order using 'first,' 'next,' 'finally'), Problem and Solution (identifies problem then proposes solutions), Description (main idea supported by details). Within these structures, individual sentences and paragraphs serve specific functions: Topic sentence (states main idea), Supporting details (provide evidence, examples, facts), Transitions (connect ideas showing relationships), Introduction (opens and sets up topic), Conclusion (wraps up and summarizes), Examples (illustrate with specific instances). Understanding how each part contributes to the whole helps readers comprehend how information is organized and ideas are developed. This passage uses a chronological/sequence structure. The passage describes the steps Maya follows to bake a cake in time order. The third sentence in question, beginning with 'Then,' serves the function of providing the third step in the baking sequence. Choice A is correct because it accurately identifies how sentence 3 contributes to the sequence structure. This sentence adds the third step in time order (pouring batter and putting in oven), moving the process forward from mixing ingredients to the actual baking, which develops the sequence structure of the passage. The sequence word 'Then' signals this is the next step after mixing. Without this sentence, there would be a gap in the process—readers wouldn't know how the mixed ingredients become a baked cake. Understanding this part's function helps readers see how the author organized information to show each step in order. Choice D is incorrect because it misidentifies the sentence's function—the sentence clearly provides specific actions and steps (pour batter, put in oven), not just a main idea. The word 'Then' indicates this is a step in a sequence, not a topic statement. The sentence includes two concrete actions that move the baking process forward. This is clearly part of the step-by-step sequence structure, not an introductory main idea. Analyzing contribution requires looking beyond content to understand function—how the part works within the whole to organize information and develop ideas. To help students analyze how text parts contribute: (1) Teach TEXT STRUCTURES explicitly with signal words - CHRONOLOGICAL/SEQUENCE: Events or steps in time order. Signal words: first, next, then, finally, before, after, during, meanwhile. Example: 'First, measure ingredients. Next, mix them. Then, bake. Finally, cool.' How parts contribute: Each sentence is a step; sequence words organize order. (2) Recognize sequence characteristics - Contains action verbs (measures, mixes, pours, puts). Shows progression through time. Each step builds on previous one. Missing a step breaks the process. (3) Practice with GRAPHIC ORGANIZERS - Flowchart with boxes for each step. Number steps in order. Draw arrows showing flow. Example teaching sequence: Find all sequence words → Number the steps → Identify what happens in each step → Check that steps flow logically → Determine where specific sentence fits → Explain how it moves process forward.
