PSAT (SAT) Sentence Completion Question.?

Well, go back and read the sentence. Miro is providing viewers with pleasure, and the sentence is structured to set you up for something similar to pleasure going in the blank. Of those choices, fun is the only one related to pleasure. Also, profundity means something like depth of intellect, so wisdom would just be redundant there. While it might make sense to you, it's not what the sentence is going for. Many, many sentence completion questions are structured so that they essentially tell you what type of word needs to go in the blank, so be on the lookout. Hope that helps!
