Q2

[monicaiannacone]

I found Q2 time consuming since I didn't set up all the frames in the beginning. I thought frames would be too time consuming but then I ended up creating all these frames for Q2 (and Q5) anyway.
I did choose E as the correct answer but I drew out all these possibilities (took a few minutes!). My common theme in PT 61 is that I did a lot of trial and error - should I be framing more (specifically on this game?)

Thanks!

I personally did not frame this game.

For question #2, we can have a strong set up that will help us with this. This is a global must be false question that concerns who could be the 2 drivers.

We have this from the rules:

F/G is the driver for H

F/K is the driver for J

A-D all looked possible when I viewed them. I am not certain that everything would have worked, but I continued to look at all of the choices. I would have simply came back to this question after doing more work so that I can use previous work to help eliminate or choose answers.

However, choice E is an obvious must be false. It states two drivers: K and L.

Notice that neither one of them can be the driver for H. Since we know H must be used, this cannot happen. That means this is our answer for this must be false question.


As for framing this game, I personally did not see anything that stood out in terms of a logical split.

2. (E)
Question Type: Unconditional
This question does not give us any conditional ("If") information, which means we don’t need to manipulate our diagram in any way. It’s also about the drivers, about whom we already made a couple of useful inferences: When Faith drives, anyone other than Hannah or Juan can drive the other car. If Faith isn’t driving, Gus and Kenneth MUST be driving. This immediately gets us to answer choice (E). However, if we were to take the answers more slowly:

(A) Faith and Gus could absolutely drive the cars. Hannah could go in either one, and Juan would be with Faith.

(B) Faith and Kenneth could absolutely drive the cars. Juan could go in either one, and Hannah would be with Faith.

(C) Faith and Lisa could absolutely drive the cars. Both Hannah and Juan would go with Faith, and the others could go wherever.

(D) Gus and Kenneth, as we already established, could absolutely drive the cars.
