If this parking policy is unpopular with the faculty, then we should modify it.

Statements

When we read Must Be True, we're primarily looking for Conditional or Math-y ideas, hoping to combine 2 or more ideas to derive something

"If" = left side

policy unpopular with → should modify it the faculty

policy unpopular with → should adopt new the students

Do those chain together? No, because there isn't any overlapping term.

Can we apply them to the remaining fact? Kind of.

FACT It's bound to be unpopular with the faculty or the students. We could actually put that into a conditional if we wanted to: ~unpop w/ faculty → unpop w/ students ~unpop w/ students → unpop w/ faculty

But mainly we could just think to ourselves

Goal

What's the same in both of these scenarios? What's true whether it's the faculty or students (or both) who find this parking policy unpopular?

We won't be keeping the policy as is (i.e. it will be modified or replaced by a new one).

21.

If the statements above are true, which one of the following must also be true?

  1. We should attempt to popularize

    Out of Scope: should popularize

    The only normative language we can derive from these statements is "should modify" or "should adopt a new one".

  4. If the parking policy is

    Opposite Trigger

    This is similar to the rule we have in the 2nd sentence, except it flips the trigger. Statements: unpopular w/ students ? should adopt new This answer: popular w/ students ? should adopt new

  5. Correct

    If this parking policy is

    Why this is right

    If the parking policy is popular with the faculty, then it is unpopular with the students, since were told that it's bound to be unpopular with one or the other. If it's unpopular with the students, we should adopt a new policy (according to 2nd sentence). So we can derive this answer: Popular Unpopular Should adopt with faculty ? with students ? new policy

    Skill tested: Must be True · how this choice captures the argument's function is the move to repeat next time.
