To support the academic efforts of its former students, the administration of a certain university has required its professors to use only papers published by former students as additional reading material. Because of this, the quality of the additional reading material has declined significantly, hampering the professors' efforts to teach effectively.
Which of the following can be inferred about the papers that would have been used as additional reading material had professors not been required to use graduates' papers?The passage says the new rule forced professors to use only former students’ papers, and
because of that the quality of the additional reading material declined significantly. That implies the alternative set of readings, the ones they would have used otherwise, were higher quality.
(A) Those papers were of better quality than the papers published by the university's former students
Yes. If switching to graduates’ papers caused a significant decline in quality, then the papers that would have been used instead must have been better on average.
This is the direct inference.(B) Those papers were written by the professors themselves.
Not stated and not implied.
(C) Those papers were ones that had been used in the past at the university as additional reading material.
They might have been, but the passage does not say so. Professors could also have changed readings over time.
(D) Those papers had been of increasingly high quality, resulting in a major educational crisis immediately following the new requirement.
No. Nothing about increasing quality, and “crisis” is invented.
(E) Those papers had been used only intermittently, but they are necessary to the proper education of the university's students.
Not supported. The passage says the decline hampered teaching, but it does not claim the previous readings were “necessary” or used intermittently.
Answer: (A)
