Wanda: It is common sense that one cannot create visual art without visual stimuli in one's work area, just as a writer needs written stimuli. β ββββββ βββββ ββββ ββββ βββββ ββββββ ββ βββββββββββ ββββ ββ βββ βββββ βββ ββ ββββ ββββββ ββ ββ βββββββ

Vernon's response indicates an implied conclusion that the items in Wandaβs studio are not effective stimuli for her artistic work. Vernon supports this conclusion with an analogy to writers: that they should read high-quality works, not tabloids. Vernon also implies that at least some of the items in Wanda's studio are junk, which is analogous to the tabloids in Vernon's analogy.
The question stem mentions an "underlying principle," which we can take to mean a principle that Vernon assumes as part of his argument. For the principle we're looking for to make sense as an unstated premise, it should form a premise-to-conclusion bridge and so better justify the argument.
So what's the gap that we're bridging? By relying on an analogy between Wanda, a visual artist, and writers, Vernon assumes that visual artists and writers are relevantly similar. In this specific context, the relevant similarity assumed is that the quality of the items they use for inspiration is important to their artistic process. Because this is the unstated part of Vernon's argument, the correct answer will affirm this similarity. The wording might vary, but in some form it will tell us that the inspiration visual artists can draw from visual stimuli is affected by the quality of those stimuli.
