Moving on to Question 7, Which one of the following cannot be true?
0:11
Let's take a look here at (A), Harvest is the last film shown on each day of the
0:17
festival. Well, could that be true Well, on Thursday it must be true, because Harvest
0:23
is the last film that is going to be shown on Thursday. It must be on Thursday, and no
0:28
film can be shown after it. Notice also on Saturday we could have Harvest be the last
0:34
film shown on Saturday. But the problem with (A) is that Harvest cannot be the last film
0:40
shown on Friday, because we need either G or L based on condition two, and no film can
0:47
be shown after G or L on that day. Therefore (A) cannot be true, and (A) would be the correct
0:54
answer.
0:57
What about (B), (C), (D), and (E) Well, I'm going to draw a quick hypothetical here that
1:04
will show you that every other answer choice here is valid.
1:09
Again, I'm going to max out, so I'm going to place three films on Thursday. Again, we
1:15
know Harvest must be the last film placed on Thursday, and then we'll have G and L.
1:21
It doesn't really matter the order of them on Thursday. Then I know I'm going to have
1:26
G or L on Friday as the last film. I'm going to have G or H on Saturday as the last film.
1:35
Now I'm going to place H on Friday and L on Saturday, because again, one of G or L is
1:42
in on Friday. The other would be out. Similarly, on Saturday, one of G or H is in. The other
1:47
would be out. Now, using this hypothetical, which is valid, notice we have each film one
1:54
time. No film is shown twice on the same day. We have H on Thursday, no film after it. We
2:02
have G or L on Friday, no film after it. We have G or H on Saturday, no film after it.
2:08
This is a valid scenario.
2:10
You notice (B), Limelight is shown on each day of the festival. Yeah, we could have
2:14
Limelight on Thursday, Limelight on Friday, and Limelight on Saturday, so (B) is out.
2:21
(C), Greed is shown second on each day of the festival. Again, you notice that
2:26
is possible. We could have Greed second on each day of the festival, so (C) could be
2:34
true, and (C) would be eliminated.
2:36
(D), A different film is shown first on each day of the festival. Again, you notice
2:41
that is possible. I could go G on Thursday, H on Friday, L on Saturday, so again, (D)
2:48
could be true, cannot be the correct answer.
2:52
Then (E), A different film is shown last on each day of the festival. Again, you
2:56
notice we could have H, we could have L, and we could have G, so again (E) could be true,
3:04
and E would be eliminated.
