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.
