Problem

Shimmering is a collective defense behavior that researchers have observed in giant honeybee colonies. When shimmering, different groups of bees flip their bodies up and down in what looks like waves. This defense is initiated when hornets hover near a colony, serving to deter the hornets from approaching the bees. Researchers hypothesize that this behavior is a specialized defense response to hornets, as it is not observed when other, larger predators approach the colony.

Clue

Look for the hypothesis or conclusion stated by the researchers. The final sentence, "Researchers hypothesize that this behavior is a specialized defense response to hornets," directly provides the controlling idea that the rest of the text explains.

Choices

4

Choice-A

Choice A is incorrect. The text only states that shimmering is not observed against larger predators. It doesn’t claim researchers are unsure of all other defenses; this is a small detail, not the central idea.

Wrong Researchers are unsure how giant honeybees defend against predators larger than hornets.

5

Choice-B

Choice B is correct. This captures the entire scope of the text. It introduces shimmering, states it’s initiated by hornets, and emphasizes the researchers' hypothesis that it’s a specialized defense against only hornets.

Correct Researchers think that shimmering in giant honeybees is a specific defense against hornets.

6

Choice-C

Choice C is incorrect. The text identifies hornets as a threat that triggers the defense, but it never states they are the main predator. This statement is an assumption not supported by the text.

Wrong Hornets are known to be the main predator of giant honeybees.

7

Choice-D

Choice D is incorrect. The passage focuses only on giant honeybees and their behavior. It does not mention any other species using shimmering, making this claim completely outside the scope of the text.

Wrong Several different species of insects use shimmering to defend against hornets.
