Be cautious when you see extreme tonality on a CR question or answer choices.Example: must, most, highest, lowest, worst, best etc
- Often, the key to elimination/selection of an answer choice lies in such extreme terms.
"Confusing-correlation-with-causation"
A favorite GMAT CR fallacy.
Example: Grandma sneezed, so a tornado hit Nebraska.
"Do so" is the correct usage when "so" refers to an action."Do it" is the correct usage when "it" refers to a noun.
As "do" generally refers to actions, "do so" is more often correct than "do it".
Commas cannot join two independent clauses.Incorrect: Amy sings, she enjoys it.Correct: Amy sings; she enjoys it.Correct: Amy sings, and she enjoys it.

In DS, when you are able to solve "too easily", you are probably missing a trap.
Q. Which integer is the highest common factor of four positive integers A, B, C, and D?(1) A= 27, B=49.
Unlike what many students will think, this statement is "Sufficient". Because no matter what "C" and "D" are, if HCF of "A" and "B" is 1, the answer is going to be "1".

The error of comma splice occurs when two independent clauses are joined using a comma.Example: Amy sings, she enjoys it.Correct: Amy sings; she enjoys it.

In DS, an answer is achieved only when the answer is "consistent".
Q. Is X a multiple of 24?(1) X is a multiple of 6.(2) X is a multiple of 4.
X = 24 satisfies both (1) and (2), leads to "Yes".X = 12 satisfies both (1) and (2), leads to "No"."Inconsistent". Hence, insufficient. Answer is E.
