Anatomical bilateral symmetry is a common trait. It follows, therefore, that it confers survival advantages on organisms. After all, if bilateral symmetry did not confer such advantages, it would not be common.

The pattern of reasoning in which one of the following arguments is most similar to that in the argument above?

(A) Since it is Sawyer who is negotiating for the city government, it must be true that the city takes the matter seriously. After all, if Sawyer had not been available, the city would have insisted that the negotiations be deferred.
(B) Clearly, no candidate is better qualified for the job than Trumbull. In fact, even to suggest that there might be a more highly qualified candidate seems absurd to those who have seen Trumbull at work.
(C) If Powell lacked superior negotiating skills, she would not have been appointed arbitrator in this case. As everyone knows, she is the appointed arbitrator, so her negotiating skills are, detractors notwithstanding, bound to be superior.
(D) Since Varga was away on vacation at the time, it must have been Rivers who conducted the secret negotiations. Any other scenario makes little sense, for Rivers never does the negotiating unless Varga is unavailable.
(E) If Wong is appointed arbitrator, a decision will be reached promptly. Since it would be absurd to appoint anyone other than Wong as arbitrator, a prompt decision can reasonably be expected.

(C)

stem follows: x hence y; if not y then not x (where x: common and y:advantage)

among choices, try to establish similar logic:

a) x hence y; if not x then not y
b) no clear logical seq
c) x then y; if not y then not x (x: lacked skills, y: not appointed)
d) not x then y; not y if x
e) x then y; not x, hence y

apologies for a bit cryptic response, but i know who is reading this ;-) ..

(1)symmetry is common so its an advantage.
(2)not an advantage will not be common

C has got this down similary.

Circular reasoning in the stem. C mimics that.

If A is true for B, A is true for C. Otherwise if A is not true for C, A is not true for B also.

If powell lacks skills, powell misses appoinment. But Powell is appointed, so she has skills.
C clearly wins.

I agree with everyone on C.

Method of reasoning in the argument is kind of "If.. then..." and "If not... then". Follow it, only C is the best candidate :D

Jdam,

this question is from LSAT, but this question will properly appear in the gmat exam as well.
There are existing gmat questions like this one.

What is this type of CR question called? Any link that explains the typical structures of an argument of CR and their logic structure. I find these questions difficult...

Thanks!
