Q23

[andrewgong01]

This was a sneaky one between "A" and "E".

"A" in itself does prevent F/H from ever going together because I goes twice and if G can't go with I then all 3 slots in the bottom row are taken, forcing FH to split.

However, on review, it turns out that "A" is too restrictive since originally, G and I could go together as :

G I H
I F/H G
== == ==
M S T


"E" does what "A" does by ensuring all three bottom slots are always filled out by either Is or Gs and hence FH can't go together but at the same time allows for G I to go together, a hypothetical case that never showed up in the questions ( i think) to trick students into picking "A".




Would you have pre phased something for this question because it seems like this question would have been easier if we had a rough idea on what we are looking for to force the same interaction. In review, I am thinking I should have gone into the question thinking of ways we can ensure F and H to split such as filling in the bottom slots or tie F/H with a different elements. Now that I look back in review this questions seems really "obvious" why A and E are the top contenders because of what they do to the bottom row but do you think there is anything we can do before a question to have such an inference ? For the actual question I just tested out answer choices; however, picked "A" without realizing it was too restrictive

I have no cleverness to offer.

I just did this games section for the first time, and it took me 26 mins total (I'm only bragging for the sake of the forthcoming thought), 4 mins of which was Q23.

I did not have a prephrase for this one. I actually set up my frames again, this time WITHOUT the ~FH rule, to see where it would leave me.

I was then waiting for a correct answer to fill in the missing pieces and make my new frames look like my original frames.

I took a first pass through all of them and none of them seemed intuitively obvious. I started poking at a couple in particular that seemed more likely to work. I was momentarily convinced that the answer was (C) until I thought of a counterexample that meant (C) was too permissive (I had a way to get FH together in Sydney).

Once I saw (E) a 2nd or 3rd time and forced myself to test it (because I was out of options), it became clear why that worked.

But, it totally eluded me both on the front end and on the first couple times I saw the answer choice. So while I'm sure many people DO react intuitively to it and see rather easily that it's right, it's certainly not something we should feel like we SHOULD have seen.

Again, immodestly, but for the sake of making you feel better:
If a Games veteran like me found it a struggle, then it couldn't have been THAT easy.
