Help

I made all the proper inferences but ended up choosing B because it seemed to have followed the logical structure the best. I don't understand why D wouldnt be considered a flawed contrapositive because its reversing the inference

@Konner, (B) is incorrect because we don't know the relative quantities of wild carts and domestic cats with high muscle-to-fat ratios. We only know that some domestic cats have it, and most wild cats have it. We don't know that one of those numbers is bigger than the other.

(D) is correct because it's one of the statements we can diagram from the stimulus.

We know

good hunter-->high muscle to fat ratio
Wild cats--most-->good hunters
Domestic cats<--some-->good hunters

From these statements, we can conclude that most wild cats have a high muscle to fat ratio, some domestic cats can kill prey up to half their body weight, and some domestic cats have a high muscle to fat ratio.

(D) is a restatement of the third conclusion we can obtain from the stimulus.
