moving on to question number nineteen. Which one of the following is a complete
0:09
and accurate list of the recycling centers in Rivertown any one of which
0:14
could recycle plastic. Well we know center 2 can't recycle plastic so we
0:19
can automatically eliminate C and E.
0:23
We also have shown from question each gene that center 3 can clearly recycle
0:28
plastic so we can eliminate answer choice A. So now all we have left to
0:33
check is center one because center three is clearly possible. So, quickly drawing
0:40
out a hypothetical can we see plastic in center one. Again, we will place wood and newsprint in
0:51
centers two which automatically paces them in center one. What do we have left.
0:56
Glass and tin. Does that violate any of my conditions.
1:02
Whenever we have wood we have newsprint. Anything in center two also appears in
1:07
center one. You only have one plastic and that plastic is not with glass so
1:12
clearly center one is possible which eliminates B meaning that D would be
1:17
the correct answer
