On Assumption Family questions, your job will be to evaluate the logic of the argument core. When doing so, it's important that you have the right mind-set. Let's look at the argument core again:
The sun rises only on Mondays-------->The sun does not rise on Fridays.
Here are two ways to think about it:
1. The real-world approach.
“No way! Terrible argument! We all know that the sun rises every day, not just on Mondays.”
2. The logical approach.
“Well, if we take the premise as a given truth, that the sun rises ONLY on Mondays, is this enough to substantiate the claim that the sun does NOT rise on Fridays? Yes. Logically speaking, this argument is sound.”
Now, most likely you haven't been studying for the LSAT for very long, but you've probably figured out that the LSAT folks aren't very interested in testing your ability to make evaluations of whether real-world facts are true or untrue. They are, however, very much interested in testing your ability to evaluate logic, the manner in which elements of an argument connect to one another.
In evaluating an argument, your job is NOT to evaluate the truth of its parts. Your job is to evaluate the logic: does the evidence given validate the conclusion? In this case, it does.
Maybe it's just my way insisting on a rigorous LSAT way.
