The correct answer is (C).
(C) Point at Issue
Step 1: Identify the Question Type
This question asks for what two people "disagree . . . about," which is a way of asking for the Point at Issue. Summarize the points of both speakers and look for the one answer with which one speaker would agree and the other speaker would disagree.
Step 2: Untangle the Stimulus
Lutsina has a positive view of futuristic science fiction. By being free from the constraint of presenting current realities, it can be more ambitious in its social visions and is therefore potentially more effective as social criticism than is conventional fiction. Priscilla doesn't view futuristic science fiction writers with such fond eyes. She claims that their ambitious views are more about technology than society, which indicates how current reality stifles their imagination. Because of that, she claims, social criticism is more effective in fiction that presents current realities: conventional fiction.
Step 3: Make a Prediction
Ultimately, Lutsina and Priscilla wind up pushing two different types of fiction as the more effective means of social criticism. Lutsina argues that futuristic science fiction is better for criticism, while Priscilla advocates for conventional fiction. The correct answer will express this point of contention.
Step 4: Evaluate the Answer Choices
(C) gets right to the heart of the argument. Lutsina would definitely agree that futuristic science fiction has more promise for social criticism, while Priscilla would disagree and argue that conventional fiction has more promise.
(A) is not supported. Lutsina would agree with this answer, since she directly states that science fiction writers envisage such social arrangements. However, while Priscilla suggests those writers are, in general, better at imagining radical technology, she may be willing to concede that some sci-fi writers have successfully envisioned new social arrangements.
(B) is Outside the Scope. The speakers aren't arguing about fiction writers' skills at writing; they're arguing about the effectiveness of their genres for social criticism.
(D) is not supported. Lutsina would most likely disagree with the statement. However, even though Priscilla mentions that these writers are better at envisioning technology than they are at envisioning social arrangements, that doesn't mean she sees that as a "shortcoming."
(E) is Outside the Scope and Extreme. Lutsina does not contend that science fiction criticizes current social arrangements by contrasting them with radically different ones. Priscilla asserts that the most effective social criticism comes from accurately portraying current realities, but that doesn't mean she finds contrasts with radically different social arrangements completely ineffective.
