The GMAT math section consists of 37 questions, each question a test of a certain math concept.

A. each question a test on a certain math concept B. all the questions a test on a certain math concept C. all the questions are tested on a certain math concept D. every question is tested on a certain math concept E. each question is tested on a certain math concept

I choose 'A'. CDE are out coz it says "question tested on....concept". Question is not tested on a concept...It tests a concept. And 'A' sounds better than 'B' with "each" in it.

Exp needed

Easy (A). You can immediately eliminate (C), (D), and (E), because they state that the questions themselves are being tested on certain math concepts, which doesn't make sense. In (A), it says that each individual question tests a certain math concept; in (B), it says that all of the questions together are a collective test on one single math concept (eg, all 37 questions test geometry). (A) is right.

The elimination came from the difference of "Test" and "Tested". Question(s) can not be tested. Between A and B, EACH fits better since its referring to "concept".
