If this parking policy is unpopular with the faculty, then we should modify it. If it is unpopular among students, we should adopt a new policy. And, it is bound to be unpopular either with the faculty or among students.

Summary

If the policy’s not popular with faculty, then we should modify it (or, by contrapositive, if we shouldn’t modify the policy, then it must be popular with faculty).

If the policy’s popular with faculty, it’s bound to be unpopular with students. (And if it’s popular with students, it’s bound to be unpopular with faculty. Popularity with one group implies unpopularity with the other.)

If the policy’s not popular with students, we should adopt a new policy.

Notable Valid Inferences

If we shouldn’t modify the existing policy, we should adopt a new policy.

If the policy’s popular with faculty, we should adopt a new policy.

If the policy’s popular with students, we should modify the policy.

A
We should attempt to popularize this parking policy among either the faculty or students.

The stimulus doesn’t suggest that any one scenario is more desirable than another. There’s no indication that the existing policy should be popular with either group, or that there’s something undesirable about the policy being unpopular.

B
We should modify this parking policy only if this will not reduce its popularity among students.

This says that modifying the policy is sufficient for not reducing its popularity among students. There are two problems here. First, modifying the policy isn’t sufficient for anything. Second, the policy is either popular or unpopular—there’s no “reduce popularity” condition.

C
We should modify this parking policy if modification will not reduce its popularity with the faculty.

The sufficient condition here is never addressed in the stimulus. The stimulus only considers what happens when the policy is popular or unpopular. There’s no discussion of reductions in popularity.

D
If this parking policy is popular among students, then we should adopt a new policy.

The stimulus states that if the policy is unpopular among students, then we should adopt a new policy. Meanwhile, if the policy is popular as (D) says, we can infer that we should modify the existing policy.

E
If this parking policy is popular with the faculty, then we should adopt a new policy.

If the policy is popular with faculty, then it must be unpopular with students (because it’s bound to be unpopular with at least one group). And if it’s unpopular with students, then we should adopt a new policy.
