### Re: Q20

We know that T is always on the 2nd team, so now that we know O is also 2nd place, we know team 2 is [T, O].

Do we know which school this is?

We know it CAN'T be G, since G has to have S on it.

So team 2 would have to be F or H.

?: [ __ , __ ] .... F/H: [T, O] .... ?: [ __ , __ ]

We know that G is earlier than H, so G can never be last. Thus, G must be first, and with G comes S.

G: [ S , __ ] .... F/H: [T, O] .... H/F: [ __ , __ ]

We know that P - N, so P needs to go 1st and N needs to go 3rd.
G: [ S , P ] .... F/H: [T, O] .... H/F: [ N , __ ]

Who's left?
M

G: [ S , P ] .... F/H: [T, O] .... H/F: [ N , M ]

Most of this scenario is locked in; the only loose part is whether it's F2 and H3, or H2 and F3.

(A) nope, G has S and P.

(B) Sure, this could work.
G: [ S , P ] .... H: [T, O] .... F: [ N , M ]

(C) nope, G has S and P.

(D) nope, P is on team G.

(E) nope, G has S and P.
