Great conversation about a tricky inference question! I actually eliminated all five answer choices my first time going through this problem, and had to take a second pass to find the correct answer.
Gilad B’s explanation of why (B) is correct is spot-on. fMRIs can generate images that look like patients’ faces. Such resemblances could be used to link fMRIs to individual patients. The sensitive information contained in fMRIs could therefore be connected to individual patients without examining labels or records. Genetic profiles, on the other hand, can ONLY be linked to patients by examining labels or records.
(A) is unsupported. It discusses "importance," but the facts in the stimulus don’t support such evaluative claims.
(C) is unsupported. How much confidence should patients feel in their privacy? Hard to say, since the stimulus tells us nothing about how well their privacy is protected.
(D) is unsupported. We know that both fMRIs and genetic profiles contain sensitive information. But we don’t know whether they contain the same pieces of sensitive information or completely different ones.
(E), like (C), discusses patients’ concern about privacy. But the stimulus offers no information about patient concern. Eliminate (E) as unsupported.
