Only senior citizens enjoy doing the daily jumble. So Aesha must not be a senior citizen, because she does not enjoy doing the daily jumble.

Which of the following arguments exhibits the same flawed reasoning as the above?

A. Only in March does Rodrigo choose to holiday in Spain. It is March, but Rodrigo is in Japan. So he must not be going to Spain.

B. Only a true pet lover could adopt Marley. Thus, since Michael is not adopting Marley, he must not be a true pet lover.

C. Only geologists enjoy the amethyst exhibit at the town fair. So Mr. Franz must not enjoy the amethyst exhibit, because he is not a geologist.

D. Since the animal in front of us is a penguin, it follows that we are in Antarctica, since one only encounters penguins in the wild when one is in Antarctica.

E. Only the best chefs can make compelling vegan escargot. So Rasheed must be able to make compelling vegan escargot, since he is one of the world’s best chefs.

a implies b ---->not b implies not a
Which of the following arguments exhibits the same flawed reasoning as the above?

B. Only a true pet lover could adopt Marley. Thus, since Michael is not adopting Marley, he must not be a true pet lover.a implies b ---->not b implies not a - correct


C. Only geologists enjoy the amethyst exhibit at the town fair. So Mr. Franz must not enjoy the amethyst exhibit, because he is not a geologist.a implies b ---->not a implies not b - reversed and so incorrect

Flaw is senior citizen - > enjoy jumble doesn't imply ~not citizen-> ~ No jumble enjoyment. (flawed contrapositive) Replicated by B.

can someone tell me how to do these kind of questions

VERITAS PREP OFFICIAL SOLUTION:

Solution: B

This Mimic the Reasoning question features difficult conditional wording. “Only x does y” can be reworded as “If you do y, then you are x”, a change of phrase that makes the question much easier to solve. “If you enjoy the jumble, you’re a senior citizen” implies two things: 1) if you enjoy the jumble, you’re a senior citizen, and 2) if you aren’t a senior citizen, you don’t enjoy the jumble. It does NOT imply that if you don’t enjoy the jumble, you’re not a senior citizen, so find an answer choice that also employs such faulty logic. (B) is the answer of choice.
