PrepTest 102

Incorrect. The stimulus provides no information as to what "should" be done, so this answer is out of scope.

Incorrect. The stimulus provides no information as to what "should" be done, so this answer is out of scope for the same reason as answer choice (A).

Incorrect. Yet another answer we can eliminate because there's no indication what "should" be done.

Incorrect. If the policy is popular among students, then the last sentence tells us that it's unpopular among faculty*. And if it's unpopular among faculty, the first sentence tells us it should be modified—not that a new policy should be adopted. This answer is thus mixing up the conditionals! (*Note that while something being popular isn't the same as not Unpopular, since the group could be neutral on it, being popular does guarantee that it's not unpopular, so it triggers that condition.)

Correct. Argument or Facts:
Facts

Question Type:
Must Be True

Stimulus Summary:
Unpopular with faculty → Change parking policy
Unpopular with students → New parking policy
Unpopular with faculty OR Unpopular with students

Answer Anticipation:
This stimulus presents two conditional statements and then an OR statement. The first two statements don't overlap, but they each do with the third statement. If we combine them, we end up with:
Change parking policy OR New parking policy

That absolutely could be the correct answer—that the parking policy will either be changed or replaced.

However, OR statements can be converted into conditional statements—we do so frequently in Logic Games, especially In/Out games. An OR relationship is one that says if one option doesn't happen, then the other does. So here, we get (when combined with the other statements):
not Unpopular w/ faculty → Unpopular w/ students → New parking policy
not Unpopular w/ students → Unpopular w/ faculty → Change parking policy

Answer Explanation:
If the policy is popular among faculty, then the last sentence tells us that it's unpopular among students*. And if it's unpopular among students, then the second sentence tells us that we should adopt a new policy, as this answer states. This answer is thus supported, so it's correct. (*Note that while something being popular isn't the same as not Unpopular, since the group could be neutral on it, being popular does guarantee that it's not unpopular, so it triggers that condition.)

Key Takeaway:
OR statements have a conditional translation that can be important to know in LR—and is absolutely important to know in LG. If one option OR another happens, then it must be true that if one doesn't happen, the other does.

Also, note our * for answers (D) and (E). For these non-binary terms (things that exist on a spectrum), not being at one extreme (e.g., popular) doesn't guarantee that it's at the other (e.g., unpopular)—something could be neither popular nor unpopular. However, if something is popular, then it can't be unpopular, and so that information can trigger sufficient conditions.
