A large Southern state university has changed its teaching practices. Formerly, instructors without PhDs taught most introductory courses; now professors with PhDs will teach all introductory classes. That means the average class size will increase from 44 students per class to 600 per class, but overall the students’ learning experience should improve.
Which one of the following is an assumption required by this argument?
(A) Requiring professors with PhDs to teach all introductory classes will mean that the university must hire more faculty with doctorates.
(B) Students tend to participate in smaller classes more than they do in large lectures, even when the lectures are supplemented by weekly discussion sections.
(C) Major private universities already have implemented a format in which professors with PhDs teach all introductory classes as large lectures.
(D) A class taught by a PhD, even in a lecture format with hundreds of students, is a better learning environment than a smaller class taught by an instructor without a PhD.
(E) Services that rank colleges and universities usually consider the percentage of classes taught by PhDs when computing rank.

The argument suggests that by having professors with PhDs teach all introductory classes, the students' learning experience will improve, despite the significant increase in class size. To strengthen this argument, we need to identify an assumption that bridges the gap between the change in teaching practices and the expected improvement in learning experience.
Let's evaluate the options:
(A) Requiring professors with PhDs to teach all introductory classes will mean that the university must hire more faculty with doctorates.
This assumption is not necessary for the argument. The argument does not depend on whether the university needs to hire more faculty; it focuses on the impact of having professors with PhDs teach introductory classes.
(B) Students tend to participate in smaller classes more than they do in large lectures, even when the lectures are supplemented by weekly discussion sections.
This assumption does not directly support the argument. The argument is about the overall improvement in the students' learning experience, not specifically about class participation.
(C) Major private universities already have implemented a format in which professors with PhDs teach all introductory classes as large lectures.
This assumption is irrelevant to the argument. Whether other universities have implemented similar formats does not necessarily strengthen the argument that the students' learning experience will improve at the Southern state university.
(D) A class taught by a PhD, even in a lecture format with hundreds of students, is a better learning environment than a smaller class taught by an instructor without a PhD.
This assumption directly supports the argument by stating that having professors with PhDs teach larger classes will still result in a better learning environment. This assumption bridges the gap between the change in teaching practices and the expected improvement in learning experience.
(E) Services that rank colleges and universities usually consider the percentage of classes taught by PhDs when computing rank.
This assumption is irrelevant to the argument. The argument is about the impact of having professors with PhDs teach introductory classes on the students' learning experience, not about how colleges and universities are ranked.
Therefore, the correct answer is:
(D) A class taught by a PhD, even in a lecture format with hundreds of students, is a better learning environment than a smaller class taught by an instructor without a PhD.

OFFICIAL EXPLANATION:
The author concludes that having classes taught by PhDs instead of instructors improves students’ learning experience, so he must assume that PhDs, even in very large classes, are somehow better at teaching than instructors in smaller ones.
Choice (A) isn’t his assumption. In fact, the reference to increased class sizes suggests that the university won’t be hiring more faculty.
Choice (B) contradicts the author’s conclusion by suggesting that student participation is a good thing.
Choice (C) is interesting information but isn’t essential to the conclusion about the practices of the particular Southern state university in the argument, especially because it doesn’t mention students’ learning experiences.
Choice (D) looks like the right answer. The author does seem to think that a class taught by a PhD is somehow superior, which explains why he thinks the change would benefit students.
Choice (E) explains why the university may want to increase classes taught by PhDs, but it doesn’t explain how that would benefit students.
Choice (D) is correct.
