DISCUSSION: The answer should capture that certain invertebrates form schools that provide various benefits.

Wrong answers will either be too narrow, too general, or an inaccurate restatement of what the passage says.

___________

1. This is too narrow. The optimal size is mentioned towards the end of the last paragraph, but it’s not the main idea.
2. Same as A (too narrow). This is discussed in paragraph 4, but not the main idea.
3. This mischaracterizes the passage. It mentioned that invertebrates form schools like fish, but it does not focus on comparing the two.
4. CORRECT. This captures the discovery of invertebrate schooling and its various benefits.
5. The passage discusses both benefits, so this overstates the emphasis on predation.
