The dean of computing must be respected by the academic staff and be competent to oversee the use of computers on campus. The only deans whom academics respect are those who hold doctoral degrees, and only someone who really knows about computers can competently oversee the use of computers on campus. Furthermore, the board of trustees has decided that the dean of computing must be selected from among this university’s staff. Therefore, the dean of computing must be a professor from this university’s computer science department.
Which one of the following is an assumption on which the argument depends?
(A) Academics respect only people who hold doctoral degrees.
(B) All of this university’s professors have obtained doctoral degrees.
(C) At this university, every professor who holds a doctoral degree in computer science really knows about computers.
(D) All academics who hold doctoral degrees are respected by their academic colleagues.
(E) Among this university’s staff members with doctoral degrees, only those in the computer science department really know about computers.
Same passage with different stem question:
LINKOFFICIAL EXPLANATION
(A) No. This is an explicit premise of the argument, not an assumption, of the argument: “The only deans whom academics respect are those who hold doctoral
degrees.”
(B) No. The passage merely states that the specific person selected must have a doctoral degree.
(C) No. The passage merely states that the specific person selected must hold a doctoral degree in computer science and really know about computers.
(D) No. The passage merely states that “The only deans whom academics respect are those who hold doctoral degrees.” (Some deans could have doctoral degrees but not be respected.)
(E) Yes. The argument sets up three criteria for the dean of computing:
1) She must have a doctoral degree.
2) She must really know about computers.
3) She must be selected from among the university’s staff.
The argument then concludes that the dean of computing must be a professor from this university’s computer science department. This assumes that of people who meet criteria 1 and 3, only those from the university’s computer science department meet criteria 2.
