Lopez: Our university is not committed to liberal arts, as evidenced by its decision to close the classics department.
Lopez's Conclusion
Our university isn't committed to liberal arts.
Lopez's Evidence
It decided to close the classics department, and the study of classical antiquity has been crucial to the liberal arts since the Renaissance.
Warrington's Response
Studying classical works is definitely crucial to a liberal arts education, but you don't need a classics department to make that happen. Other departments often engage in that study.
Evaluate
Our job is to characterize the type of rebuttal or response Warrington offered. We can consider the Big 8 repertoire of Method answers (the most common structures they test): - analogy - counter/example for general claim - implications of logic - ruling out alternatives - suggesting alternate explanation - calling out a dubious assumption - raising an overlooked consideration - making a definition or distinction
If we were choosing from this list (we don't need to), we would probably go with "raising an overlooked consideration" or "making a distinction".
Warrington is saying to Lopez,
Goal
Raising the overlooked consideration that the study of classical works will still be done in other departments helps Warrington to make a distinction between "getting rid of the classic department" and "getting rid of the study of classical works".
Let's pick any answer that we can match to the text.
