The second game of the June 2007 LSAT states, Exactly three films Greed, Harvest, and
0:10
Limelight are shown during a film club s festival held on Thursday, Friday, and Saturday.
0:16
Each film is shown at least once during the festival but never more than once on a given
0:21
day. On each day at least one film is shown. Films are shown one at a time. The following
0:28
conditions apply:
0:31
So the first thing we know is that we have three films and those films are going to be
0:35
Greed, Harvest, and Limelight.
0:41
We also know that this festival is going to be held on three days, Thursday, Friday, and
0:48
Saturday, and on each day at least one film is shown. Again, we have three days; Thursday,
0:56
Friday, and Saturday. On each of these days, at least one of the films is shown. We also
1:04
know that each film is shown at least once during the festival, so we know that we have
1:11
at least one G, at least one H, and at least one L, but never more than once on any given
1:18
day. Well, what that tells us is that we have at least one film shown every day, and max
1:25
three, because we can't have any film show up more than once, so we have max three for
1:36
each day because we can only have G, H, and L. No one can show up more than once.
1:44
So at least one, max three, and now let's turn our attention to the conditions. The
1:50
first condition tells us, On Thursday Harvest is shown and no film is shown after it on
1:58
that day. We know Harvest is going to be on Thursday and we also know that if any other
2:04
film is shown on Thursday it has to be shown before Harvest. Turning our attention to the
2:11
second condition, On Friday, either Greed or Limelight but not both is shown, and no
2:18
film is shown after it on that day. We know we had either Greed or Limelight but
2:27
not both. You notice what that does is it changes our max three on Friday to a maximum
2:35
of two now because we can't have both G and L. Again, as we saw previously, if anything
2:45
is shown on that day, Friday, it must be shown before G or L.
2:53
Moving to the third condition, On Saturday either Greed or Harvest but not both is shown
2:59
and no film is shown after it on that day. So again on Saturday we have either Greed
3:07
or Harvest but again not both, which again changes our max from three to two. Again,
3:17
if any film shows up on Saturday, it must be played before G or H.
3:28
There you have it. That is the setup for this game. Now that we have this setup, let's turn
3:33
our attention to the questions.
