BLACKBELT! Thank you for the nice hint on LSAT. These tests actually seem to be tougher on verbal part. Admire your resourcefulness.

Taylor: Researchers at a local university claim that 61 percent of the information transferred during a conversation is communicated through nonverbal signals. But this claim, like all such mathematically precise claims, is suspect, because
claims of such exactitude could never be established by science.

Sandra: While precision is unobtainable in many areas of life, it is commonplace in others. Many scientific disciplines obtain extremely precise results, which should not be doubted merely because of their precision.

The statements above provide the most support for holding that Sandra would disagree with Taylor about
which one of the following statements?

(A) Research might reveal that 61 percent of the information taken in during a conversation is communicated through nonverbal signals.
(B) It is possible to determine whether 61 percent of the information taken in during a conversation is communicated through nonverbal signals.
(C) The study of verbal and nonverbal communication is an area where one cannot expect great precision in one’s research results.
(D) Some sciences can yield mathematically precise results that are not inherently suspect.
(E) If inherently suspect claims are usually false, then the majority of claims made by scientists
are false as well.

i think its C as well

Very nice. And that's why OA is D.

I actually picked C in the begining and was quite sure about it.

LSAT's CRs are a way tougher. But unless you realize the difference with the GMAT, i would not recommend practicing them cause they may do more harm.
