Can data sufficiency answer be in the stem

by YKNJS25 » Wed Jun 22, 2016 3:40 pm
Was just wondering if the answer to a data sufficiency question could ever be in the question stem. If that were to be the case would the correct answer be that both 1 and 2 can answer the question or neither?

My guess is this is not possible but thought I'd ask the experts! :)

Your guess is correct; the target question is always impossible to answer (without additional information).

Hi YKNJS25,

In a DS question, whatever information (if any) that is included at the start of the prompt is NEVER enough to answer the question that is asked. If you think that it is, then you're either working with some incorrect practice materials or you're not thinking thoroughly enough about what the answer to the question COULD be.

One word answer: NO
There is a reason that the additional information is given to you :)

There has been at least one official DS problem in which the question stem could be answered without additional information from the two statements:

However, this problem -- which appeared in GMATPrep -- should be considered FLAWED.
Generally, the information in the prompt will never be sufficient on its own to answer the question stem.

It shouldn't be, though as Mitch points out, the test writers occasionally goof, but in principle, this shouldn't happen.

That said, there are a number of official problems in GMATPrep that have the wrong solution, and for whatever reason the GMAC hasn't (as far as I know) acknowledged or fixed them - I could be wrong about this, but the flawed questions are still there in a download in 2016 - so there's an outside shot you might have an error on your actual exam on test day.
