“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.
If the statements above are true, which one of the following must also be true?
(A)
Some cats that have a high muscle-to-fat ratio
are not good hunters. - WRONG. There are no exception as per passage.
(B) A smaller
number of domestic cats than wild cats have a high muscle-to-fat ratio. - WRONG. Red Flag. Numbers have no certainty when probability and percentage terms are used in passage.
(C)
All cats that are
bad hunters have a low muscle-to-fat ratio. - WRONG. Reverse logic. Can't be said so.
(D) Some cats that have a high muscle-to-fat ratio are domestic. - CORRECT.
(E)
All cats that have a high muscle-to-fat ratio
can kill prey that weigh up to half their body weight. - WRONG. Not possible as there may be some exception.
