24.   Advertisement: In today’s world, you make a statement about the person you are by the car you own. The message of the SKX Mach-5 is unambiguous: Its owner is Dynamic, Aggressive, and Successful. Shouldn’t you own an SKX Mach-5?

If the claims made in the advertisement are true, which one of the following must also be true on the basis of them?

(A) Anyone who is dynamic and aggressive is also successful.

(B) Anyone who is not both dynamic and successful would misrepresent himself or herself by being the owner of an SKX Mach-5.

(C) People who buy the SKX Mach-5 are usually more aggressive than people who buy other cars.

(D) No car other than the SKX Mach-5 announces that its owner is successful.

(E) Almost no one would fail to recognize the kind of person who would choose to own an SKX Mach-5.

The answer is B.My choice is E ,why B and why not E. I do not understand the first sectence especially. Thanks.

This question is easier to explain using logic terms.

Car → Kind of person, meaning, if you know what car this person owns, you will know what type of person he is, so "car" is sufficient condition, and "kind of person" is necessary condition.

Answer B is a contra-positive: negate kind of person → negate car, meaning, if this person does not have those personailities that are supposed to be found on the owner of this car, he will not own this car, therefore, he would misrepresent himself by owning the car. Because B is such an obvious contra-positive, contrapositive is the right answer, so other answers will just be eliminated.

thanks , I got it
