Professor: Many introductory undergraduate science courses are intended to be "proving grounds," that is, they are designed to be so demanding that only those students most committed to being science majors will receive passing grades in these courses. However, studies show that some of the students in these very demanding introductory courses who are least enthusiastic about science receive passing grades in these courses. Hence, designing introductory science courses to serve as proving grounds has not served its intended purpose.
Which one of the following is an assumption that the professor's argument requires?
(A) If some of the students who are most enthusiastic about science do not receive passing grades in introductory science courses, then designing these courses to serve as proving grounds has been unsuccessful.
(B) Science departments need a way to ensure that only those students most committed to being science majors will receive passing grades in introductory science courses.
(C) Some of the students in the very demanding introductory science courses who are most enthusiastic about science do not receive passing grades in those courses.
(D) None of the students in the very demanding introductory science courses who are least enthusiastic about science are among the students most committed to being science majors.
(E) Introductory science courses should not continue to be designed to serve as proving grounds if doing so has not served its intended purpose.

Argument Breakdown:
Premise 1: Introductory science courses are designed as proving grounds, meaning:
Only students most committed to being science majors should pass.
Premise 2: But studies show that some students who are least enthusiastic about science still receive passing grades.
Conclusion: Therefore, designing these courses as proving grounds has not served its intended purpose.
What is the gap (assumption) in this reasoning?
The professor concludes the system failed just because some least enthusiastic students passed. But this only undermines the purpose if those students who passed aren’t also committed to being science majors.
So, the assumption must link:
"least enthusiastic about science" ⟶ not committed to being science majors.

Hence, designing introductory science courses to serve as proving grounds has not served its intended purpose.
Which one of the following is an assumption that the professor's argument requires?
The professor argues that the courses failed as proving grounds because some students who were least enthusiastic about science still passed. The missing assumption is that those least enthusiastic students were not among the students most committed to becoming science majors.
(A) If some of the students who are most enthusiastic about science do not receive passing grades in introductory science courses, then designing these courses to serve as proving grounds has been unsuccessful.
This is not required. The argument is about least enthusiastic students passing, not most enthusiastic students failing.
(B) Science departments need a way to ensure that only those students most committed to being science majors will receive passing grades in introductory science courses.
This is not required. The argument is about whether these courses achieved their intended purpose, not whether science departments need such a system.
(C) Some of the students in the very demanding introductory science courses who are most enthusiastic about science do not receive passing grades in those courses.
This is not required. The professor does not need to show that enthusiastic students failed.
(D) None of the students in the very demanding introductory science courses who are least enthusiastic about science are among the students most committed to being science majors.
This is correct. If the least enthusiastic students who passed were still among the most committed to being science majors, then their passing would not show failure. So the argument requires assuming that least enthusiastic students are not among the most committed.
(E) Introductory science courses should not continue to be designed to serve as proving grounds if doing so has not served its intended purpose.
This is not required. The conclusion says the courses failed to serve their purpose, not that the courses should be changed.
Answer: (D)
