Stuck between A and D
Hello, I was stuck between answer choice A and answer choice D, although I went with D, would you be able to provide an explanation for answer choice A and why D was the correct choice. Although I got it correct, I did get stuck on this problem and would like to make sure it doesn't happen again. Thank you!

This question has quite a few elements to keep track of.
Once you combine the sufficient necessary statements as in the solution, you will find that the tricky part to this question was figuring out what could not occur. In other words, must be false.
For answer choice A, we need to consider what we know about those who have no time for leisure activities.
As it turns out, the only condition that is triggered from having no time for leisure activities is not being happy.
It has no definite relationship with working 18+ hours or not.
The original condition involving these two were the following:
Time for leisure activities -> NOT 18+ hours work a day
But we do not know definitively what the case is when we negate the sufficient condition. This is why we cannot conclude that A must be false. We can only conclude what occurs if someone does work 18+ hours a day. We would know that they do not have time for leisure activities. This is the contrapositive.
Make sure that you are not making deductions from reversals or negations, without doing both.
I hope this helps. Please let me know if you have any other questions or would like to expand further.
