Hi bonbon,
For a question like this (like most questions in Reading Comprehension), it is critical that you return to the passage (in this case paragraph one) and you prephrase what happens in this paragraph before looking at the answers. If you do this correctly, your prephrase should be similar to Answer D and not at all similar to Answer B.
The paragraph begins with describing the deficiency/problem (the lack of sources), then the paragraph elaborates on the problem by listing which types of information the current sources do not answer, and then the paragraph ends with the only possible solution, "only quantitative studies of large numbers of cases would allow even a guess at the answers to these questions" (my emphasis)(lines 25-27).
This prephrase perfectly matches Answer D.
The easiest way to eliminate Answer B is that it doesn't mention the sole/only solution that is discussed at the end of the paragraph, but Answer B is actually wrong for multiple reasons. In fact, the only part that Answer B gets correct is the first part, "a problem is described."
