“Good hunter” and “bad hunter” are standard terms in the study of cats. Good hunters can kill prey that weigh up to half their body weight. All good hunters have a high muscle-to-fat ratio. Most wild cats are good hunters, but some domestic cats are good hunters as well.

Summary
The stimulus can be diagrammed as follows:

Notable Valid Inferences
Most wildcats have a high muscle-to-fat ratio.

Most wildcats can kill prey that weigh up to half of their body weight.

Some cats that can kill prey that weigh up to half of their body weight have a high muscle-to-fat ratio.

Some domestic cats can kill prey that weigh up to half of their body weight.

Some domestic cats have a high muscle-to-fat ratio.

A
Some cats that have a high muscle-to-fat ratio are not good hunters.
This could be false. We know that all good hunters have a high muscle-to-fat ratio. It could be the case that some of the cats with a high muscle-to-fat ratio are not good hunters.
B
A smaller number of domestic cats than wild cats have a high muscle-to-fat ratio.
This could be false. We don’t have any information about the numbers of domestic cats or wild cats.
C
All cats that are bad hunters have a low muscle-to-fat ratio.
This could be false. We don’t know enough about cats that are bad hunters.
D
Some cats that have a high muscle-to-fat ratio are domestic.
This must be true. As shown in the diagram, we see that we can infer that some domestic cats have a high muscle-to-fat ratio.
E
All cats that have a high muscle-to-fat ratio can kill prey that weigh up to half their body weight.
This could be false. We know that some cats with a high muscle-to-fat ratio can kill prey that weigh up to half their body weight, but we don’t know if this is true for all of these cats.
