Hi Rikuto,

This is a must be true, so we should read the stimulus carefully, and diagram if we choose to do so. The stimulus describes an experiment, and there are no real quantifiers or sufficient and necessary language (with the possible exception of the last sentence), so I probably wouldn't diagram this, and would rather just make sure I have a strong understanding of the experiment. We are told that six students were presented with a patient with symptoms, and a doctor asked them how to rule out a certain condition, which varied for each of the students. LAter, each student was given a patient with similar symptoms alone, and the first test they ran was the one the doctor had mentioned a week earlier.


(A) Appears to be strongly supported. We know that each of the students was presented with a different condition in the first week, and that each of the students chose the same condition in the second week. So, it must follow that each of them chose different conditions in week two.

(B) Is not supported, we have nothing in the passage that tells us the maximum number of students who knew what was most likely to cause the symptoms, and in fact.

(C) We know nothing about the second attending physician

(D) We are never told what the actual cause was, if it was one of the six tested conditions, or if the patient was even ill at all- or maybe just playing along with the experiment.

(E) We are never told anything about the students' awareness or not of how many things could cause the symptoms.

So, we can select A.
