I was contemplating between B and E. A is obviously outside the scope of the question and is wrong in several ways. The way I perceived it to be wrong flawed because I assumed that it is commonsensical to apply labels in the medical field. C and D uses "most" which is indicates the degree, and nowhere in the stim talks about the level of information nor of the degree of the patients' sureness in their privacy - but I could be wrong. Due to self-doubt, I grouped them together to deal with later if all else failed.

E is incorrect because it assumes people are more fearful of fMRIs than of genetic profiles. Patients' feedback is not included in the stim. It must be wrong.

The ability to create the patient's face might make fMRI sounds like it poses a greater threat, but that's an assumption. The stim does not say anything about fMRIs posing a greater security threat. It simply highlights that fMRIs have a feature that genetic profiles lack. The passage’s point is that both fMRIs and genetic profiles can threaten privacy, but fMRIs contain additional information - which means there are more possible avenues for privacy compromise, not necessarily a greater degree of threat.

These questions are easier for me because there is a general principle or claim that draws on the pattern between the premise and the conclusion, making the correct answer predictable.

Awesome explanation.

Some arguments are stronger than others because their support are stronger than others'.
