Question number eighteen: Which one of the following could be an accurate account of all the
0:11
kinds of material recycled at each recycling center in Rivertown? Alright so
0:16
let's go to the rules one at a time and eliminate answer choices that violate our
0:19
rules. Our first rule was that if we recycle wood we also have to recycle
0:25
newsprint. So notice in answer choice (A) in center 3 we see wood in center 3 but
0:33
we do not see newsprint. Therefore (A) violates rule number one and (A) would
0:39
be eliminated. None of the other answer choices violate condition number one so
0:44
lets turn our attention to condition two. If you are recycled by center 2 you must
0:49
be recycled by center 1. Well notice in answer choice (C) we have glass, newsprint
0:57
and tin in center 2 but we are missing tin in center 1. We see glass, newsprint
1:05
and wood as opposed to glass, newsprint and tin. So (C) violates our second condition (C)
1:14
would be eliminated. (D) is fine and (E) is also fine. (B) also no problem with
1:20
condition number 2. Turning our attention to our third rule we only have one plastic.
1:24
Well automatically we can eliminate answer choice (E). We see two plastics in recycle center 1 and
1:31
in recycle center 2. And then don't forget where we see plastic we cannot
1:37
see glass you notice in answer choice (D) center 1 has glass and plastic. So (D)
1:43
does not follow meaning that (B) here would be our correct answer. Again here just drawing
1:49
this out so we have this hypothetical readily available just in case we can
1:55
use it on previous work.
