Q14

[andrewgong01]

For this question (and similar ones like these) would brute forcing be the best way forward? Using the rules given above not many choices could be eliminated and prior work did not help much ( I did it in the end) and ended up just going through the list and tried each one. Was there a faster way to approach this problem ?

In the past when I get these really broad CBT (i.e. CBT questions without a new hypothetical condition) I would use prior work but I usually end up reluctantly just brute forcing my way down

There's definitely nothing wrong with brute force! I use it all the time. It's only bad if we stare blankly at the page a long time before committing to brute force.

As you said, on these global questions, you try to use prior work to get rid of stuff or use superficial understanding of the rules to get rid of stuff, and then you switch to brute force for what's left.

I would check Q14 against the rules:
- Rule 1 doesn't seem to kill anything
- Rule 2 kills (B)
- Rule 3 doesn't seem to kill anything
- Rule 4 kills (A).

So at least we only have 3 options to test. At that point, I would favor starting with any answer choice that triggers something obvious.

G - J seems easy-ish to look for.

(D) looks bad, since J on Tues morning forces G onto Monday, with S. Eliminate.

Then we might have to write out (A) and (E), although (E) also forces G on Monday with S.
