Critical Reasoning (CR) | Re: Primatologist: Monkeys and apes of most species groom

On these questions, you always want to start by cutting straight to the heart of the passage. Here, the conclusion is that the main function of grooming in apes monkeys is social cohesion.

So what are those bold parts doing? The first seems like evidence or a premise, informing us that in many species grooming goes way beyond what's necessary to keep fur pristine. The second also seems like a premise: grooming isn't about health benefits.

Put another way, the bold portions support the conclusion by pointing out what grooming isn't really used for -- it's not just about keeping the fur nice and shiny, and it's not just about health benefits.

To theanswers!

Nope. The second boldface statement is definitely not a conclusion. Kill(A).
