Can someone please explain answer choice A

Hi @liwenong28, Happy to help! This is definitely a bit confusing. We know that "all great art involves original ideas." Great art --> Original ideas No original ideas --> Not great art We also know that "any art that is not influential cannot be great art." In other words, all great art is influential. Great art --> Influential Not influential --> Not great art While we cannot combine these statements in the traditional sense, we can conclude that all great art is influential and involves original ideas. Therefore, at least some art (i.e. great art) is influential and involves original ideas. Hope this helps! Please let us know if you have any further questions.
