When chimpanzees become angry at other chimpanzees, they often engage in what primatologists call "threat gestures": ...

@johnny I am assuming you are asking what the problem with (E) is since (E) is not actually a flaw.

This is a Paradox question so we are looking for the answer that serves as a possible explanation for the discrepancy in the stimulus.

What is the discrepancy here?

That "threat gestures" are rarely followed by physical attacks and physical attacks are almost never preceded by threat gestures.

(E) does not resolve this discrepancy here because it does not address why physical attacks are not preceded by threat gestures.

Compare that with (B), "Making threat gestures helps chimpanzees vent aggressive feelings and thereby avoid physical aggression."

This explains both why threat gestures are not followed by attacks and why attacks are not preceded by threat gestures.

Hope that helps! Please let us know if you have any other questions.
