    Let's diagram: "Most successful entrepreneurs work at least 18 hours a day," P1: SE-most-W@L18H W@L18H-some-SE "and no one who works at least 18 hours a day has time for leisure activities." P2: W@L18H ==> not TLA TLA ==> not W@L18H "But all happy entrepreneurs have time for leisure activities." P3: HE ==> TLA not TLA ==> not HE We are looking for the answer choice that CANNOT be true. Let's diagram answer choice (D): HE-some-W@L18H Well we know that if you are a happy entrepreneur, then you must have time for leisure activities. We also know that if you have time for leisure activities, you do not work at least 18 hours day. HE ==> TLA ==> not W@L18H Thus, through the transitive property, we can conclude: HE ==> not W@L18H. So answer choice (D) cannot be true. Hope that helped! Please let us know if you have any other questions.

    (A) Anyone who has no time for leisure activities works at least 18 hours a day. So, we can rewrite this: "If you have no time for leisure activities, then you work at least 18 hours a day." not TLA ==> W@L18H not W@L18H ==> TLA (B) Some entrepreneurs who work at least 18 hours a day are successful. EW@L18H-some-S S-some-EW@L18H (C) Some happy entrepreneurs are successful. HE-some-S S-some-HE (D) Some entrepreneurs who work at least 18 hours a day are happy HE-some-W@L18H W@L18H-some-HE (E) Some successful entrepreneurs work less than 18 hours a day. SE-some-not W@L18H not W@L18H-some-SE Hope that was helpful! Please let us know if you have any other questions.

    if the passage states: "and no one who works at least 18 hours a day has time for leisure activities." P2: W@L18H ==> not TLA TLA ==> not W@L18H and (A) Anyone who has no time for leisure activities works at least 18 hours a day. So, we can rewrite this: "If you have no time for leisure activities, then you work at least 18 hours a day." not TLA ==> W@L18H not W@L18H ==> TLA wouldn't this violate the "don't just reverse" premise of sufficient and necessary conditions?
