Hello all!!

Can someone please explain this? I thought I understood suf vs. nec, but then I got to this question. It just won't click what is happening in the argument, and the videos are not helping me as much.

Thanks!
Caitlin

    The book argues people who are successful in business (sufficient condition) have benefitted from a lot of luck (necessary condition).
    It can be diagrammed like this: success --> luck

    The stimulus them goes on the say that the argument is false because rather success (sufficient condition) requires a lot of hard work (necessary condition).
    It can be diagrammed like this: success --> hard work

    This is an error of reasoning because the stimulus implies that if "success --> hard work" is true then "success --> luck" must be false. However, both of these can be true as the same time.

    C is correct because if the book author's argument had been misinterpreted as them saying that anyone who is lucky is successful (luck [sufficient condition] --> success [necessary condition]), then this would be at odds with the "success --> hard work" principle. It would suggest that luck alone is sufficient to be successful; this is something we know to be false based on the last sentence of the stimulus. However, that is not what the book said; rather is said "success --> luck".
