Q14

[ShehryarB30]

Could you pls explain this?

From the setup, we know that we have
Gw / Fo
and
Hw / Io (this is on wall 4)

We know the second one because every wall will have an 'o' and a 'w', and the only 'w' we can put with Io is Hw.
- Gw is already being used
- Iw can't go with Io because of rule 2
- Fw can't go with Io because of rule 3

For Q14, if Ho is on wall 2 let's think about our diagram:

....up.....low
1:
2: (.....Ho...)
3:
4: Hw ... Io

Who's left?
Gw/Fo on 1 or 3.
Go must be on whichever of 1 or 3 isn't taken.
Iw, Fw, one of whom will go with Ho and one of whom will go with Go.

For the purposes of this question stem, who could go with Ho?
Iw or Fw

(A) We can never have two o's on the same wall
(B) Gw is with Fo on 1 or 3.
(C) We can never have two o's on the same wall
(D) Hw is in 4.
(E) YES!
