Hi @tmorrison10, thanks for your post. You mean to ask about Question 4, we believe, not Question 3.As explained in the video, the stimulus presents an argument. Helen's conclusion is that "it was wrong of my brother Mark to tell our mother that the reason he had missed her party the evening before was that he had been in a traffic accident. . . ."
Why? Because "saying something that is false can never be other than morally wrong," and Mark said something that was false - there had not been an accident.
You have the conclusion of Helen's argument wrong. Her conclusion is about her brother Mark, specifically. The premise she gives in support of her conclusion that what Mark did was wrong is a principle - namely, the principle that "saying something that is false can never be other than morally wrong."
Hope this helps. Please let us know if you have any additional questions.
