The correct answer choice is (C). Please let us know if you have any additional questions.

Hi, could you also explain why A isnt correct?

@melissakaijukags of course! Let's break it down. "Some twentieth-century are is great art." 20thA-some-GA "All great art involves original ideas . . . " GA ==> OI not OI ==> not GA " . . . any art that is not influential cannot be great art." Not I ==> not GA GA ==> I This is a Bizarro Must Be True question, so the four incorrect answer choices must be true, while the correct answer choice is not necessarily true. (A) follows logically from the following: GA ==> I GA ==> OI Remember, we can convert an S & N statement into a some statement (assuming the existence of the sufficient condition). So we can convert either one of these S & N statements into a some statement as follows: I-some-GA We can then combine with the other S & N statement as follows: I-some-GA ==> OI To conclude: I-some-OI (i.e. "Some influential art involves original ideas.") So (A) must be true and (A) would be eliminated. Hope that helps! Please let us know if you have any other questions.
