The LSAT will often ask a fairly simple question in an overly complicated way. This is one such example. As you see more questions, you will become more comfortable with the LSAT language. Here's my simplification of the question stem:
The passage claims that day care is an imperfect solution. Which of the following is NOT given by the author in support of this claim?
The daycare discussion begins on line 5. What are the problems with daycare? 1. not always affordable 2. not always suitable 3. parents still must deal with emergencies such as sickness 4. it does not provide meaningful time between parents and their children
We are able to eliminate answer choices A, B, C, and E.
This leaves us with D. The passage never discusses vacations, which makes D the correct answer.
Make sure you pay attention to the bold words like "EXCEPT" that indicate a bizarro question.
