Question #7
How was it determined that transitive property needed to be used in this question? This jump in logic was never explained!
How do you get to the logic chain: Popular with faculty and not popular with students then a new policy must be adopted
I am struggling specifically because the language in the question refers to modifying the parking policy for faculty, not adopting a new one. It only refers to a new parking policy for students.

We're told that if this parking policy is unpopular with faculty, then we should modify it.
UF - ->MP
We're then told that if it is unpopular among students, we should adopt a new policy.
US - ->ANP
We're finally told that the parking policy is bound to be unpopular either with the faculty or among students. This means that it will be unpopular with at least one of these groups.
/UF - >US
/US - >UF
The last sentence of the stimulus is the key to solving this problem, and this appears to be where you became confused. We know that US or UF has to be triggered, as we noted above.
We also know that no matter what, either MP or ANP will be triggered since either US or UF will be triggered.
Answer A is incorrect because it describes what we "should" popularize, and this is not mentioned at all in the stimulus. This doesn't have to be true at all.
Answer B is incorrect because it places MP (modifying the policy) in the sufficient condition, and we know from the stimulus and the diagrams above that MP is in the necessary condition, so this is incorrect.
Answer C is incorrect because it's saying /RPF - ->MP; however, what triggers MP is UF (unpopular with faculty), and this does not mean the same thing as not reducing popularity with faculty (/RPF).
Answer D is incorrect because it's saying if the parking policy is POPULAR among students, then we should adopt a new policy (ANP). However, we know that ANP is triggered by US, and answer D is saying that /US (popular among students) triggers ANP. This is incorrect.
Answer E is correct because it says if the parking policy is popular with the faculty (which is the sufficient condition for E), then we know that it must be unpopular with the students. We know this from the last sentence of the stimulus, which gave us
/UF - >US
Now that we know that it's unpopular with students, we also know that ANP (adopt a new policy) must be triggered, and this is exactly what answer E has in its necessary condition.
Answer E looks like this:
/UF - >ANP
And we know that /UF triggers US, which thereby triggers ANP
/UF - >US - ->ANP
This is why E must be true.
Does this make sense? Let us know if you have any more questions!

This helps me understand this better! Thank you. As a follow up, why does it seem that in the video (when using popular instead of unpopular) the last sentence negates the necessary instead of the sufficient like you did here. How do I think about the rule in the 'popular' case?

^^ please answer. Is it okay to diagram it as either UF or PF??
