Most successful entrepreneurs work at least 18 hours a day, and no one who works at least 18 hours a day has time for...

Why D?
Why is D the correct answer? E also seems like it could be the answer too. I don't understand how statement E ("some successful entrepreneurs work less than 18 hours a day") could also be true. After all, statement E is diagramed as:
SE -some- not WAL18H and the first premise in the stimulus is diagramed as either "SE - most - WAL18H" or "WAL18H - some - SE". I thought quantity statements don't have contrapositives.

@chamoritta112 (D) says, "Some entrepreneurs who work at least 18 hours a day are happy."
This cannot be true because we know that anyone who works at least 18 hours a day does not have time for leisure activities and any entrepreneur who does not have time for leisure activities is not a happy entrepreneur.
W>18hrs ==> not LA ==> not HE
(D) is saying W>18hrs-some-HE which directly conflicts (i.e. shows sufficient without necessary).
Let's compare with (E), "Some successful entrepreneurs work less than 18 hours a day."
Nothing in the stimulus conflicts with (E) so (E) could be true.
The fact that "most successful entrepreneurs work at least 18 hours a day" that does not rule out the possibility that there is a successful entrepreneur who works less than 18 hours per day.
Hope that helps! Please let us know if you have any other questions.
