Aren't "MOST" statements reversible to "SOME"?

Hi, We learned from the videos that X-MOST-Y can be reversed to Y-SOME-X. Accordingly, the first sentence is diagrammed with MOST as such: Successful Entrepreneurs-MOST-W>=18H/D. However, it could also be diagrammed as W>=18H/D-SOME-Successful Entrepreneurs. And since "SOME" statements are reversible, it would follow the following diagram: Successful Entrepreneurs-SOME-W>=18H/D. Combining the latter "SOME" inference with the sentences 2 and 3, we get the following: Successful Entrepreneurs-SOME-W.=18H/D----->NO Time for Leisure Activities----->NOT Happy Entrepreneurs, which can be simplifies as such: Successful Entrepreneur-SOME-NOT Happy Entrepreneurs Again, since "SOME" statements are reversible, the latter inference can be diagrammed as following: NOT Happy Entrepreneurs-SOME-Successful Entrepreneur Well this inference (i.e., "NOT Happy Entrepreneurs-SOME-Successful Entrepreneur") is as contradictory to answer choice C and is answer-choice D. Therefore, D is not superior to C. Please, someone needs to reach out to LSAC writers. EVERY POINT COUNTS!
