Moving on to the final question of the June 2007 logic games section. Question
0:07
23 which tells us if center 1 is the only recycling center that recycles wood
0:12
then which one of the following could be a complete and accurate list of the kinds
0:16
of material at one of the recycling centers
0:20
recycles. Alright so let's draw out a quick hypothetical here. Again we know at least
0:24
two in each. Center 1 is the only center recycling wood. So what we know
0:34
now, again we know plastic can't be in 2 but now we know wood can't be in 2
0:38
wood also cant be in 3 which tells us that we're in this scenario where
0:45
center 2 has two materials and center one has three materials because again
0:51
wood cannot be in center 2 and if center 2 had three materials center 1 and 2 would
0:57
have to match. So whatever we place in center 2 in going to join center 1. We also know
1:06
that if you have wood you have to have newsprint. So newsprint must be in center 1
1:13
and since we know that the remaining two in center 1 are coming from center 2
1:17
newsprint must also be present in center 2. Now you should notice that plastic
1:24
cannot be in center 1 because if plastic was in center 1 that would fill up our
1:30
three spots with materials
1:33
but we can't have plastic or wood appear in 2 so there's no way everything that appears
1:41
in 2 would be appearing in 1 because we would have tin and tin would not be present. So plastic cannot be in
1:48
center 1 which means plastic must be in center 3. Again we know plastic can't
1:54
be with glass and we have to have a glass present which pushes glass into
1:59
2 and into 1. Who's left? Well, T hasn't been placed so tin must be in
2:08
center 3. Again now we're looking for which of the following could be complete
2:13
and accurate list of the kinds of materials
2:15
that one of the recycling center recycles. So you should notice that
2:19
every answer choice only has two materials so we're only going be considering 2 and 3 since
2:24
we know center 1 has three materials. So turning our attention to (A) plastic and
2:30
tin and you notice center 3 we see plastic and tin. So (A) here would be
2:37
the correct answer. It could be a complete and accurate list of center 3 so (A) would
2:42
be correct. But again just making sure notice newsprint and wood never a
2:49
possibility. The only place we see newsprint and wood is in center one where we
2:52
also have glass. Again just based on the fact that wood is president we know
2:57
wood doesn't show up anywhere but center 1 and center 1 has three
3:01
materials. So (B) and (D)
3:03
can be eliminated based on that. Newsprint and tin again never possible. And lastly
3:10
glass and tin again never possible. Proving again that (A) here would be the correct answer.
3:15
And that brings us to the end of our discussion of the June 2007 LSAT games.
