Which brings us to question 17 the final question in this game. Which one of the
0:08
following must be true about Freedom's schedule of voyages? And this is a fabulous
0:13
example of the time trap question. Coming out and asking you what must be true. Alright so
0:18
first we want to try to use previous hypotheticals as counter examples to
0:22
eliminate as many answer choices as possible But again before checking every answer choice we want to
0:27
scan them as well to make sure we haven't already made this deduction.
0:30
So let's take a closer look at the answer choices turning our attention first to (A). Freedom
0:36
makes a voyage to Guadaoupe either in week 1 or else in week 2. You notice in all of our previous
0:42
work we have Guadaloupe either in week 1 or in week 2 for all of our previous
0:49
hypotheticals. But again that doesn't necessarily mean it must be true.
0:54
We could have a scenario that we haven't drawn out yet but we don't see Guadalupe in
0:59
week 1 or week 2 so let's hold (A). Moving to (B). Freedom makes a voyage to Martinique either in
1:07
week 2 or else in week 3. And if you notice in our previous work from
1:13
question 13 our top scenario week 2 and 3 is G in J. So (B) doesn't have to be true.
1:23
Again coming directly from our previous work from question number 13.
1:28
Turning our attention to (C). Freedom makes at most two voyages to Guadaloupe. Again in none of
1:36
our previous work do we see Guadeloupe more than twice. Again don't forget that in this
1:42
scenario over here these are reverse dual options. We're gonna have one Martinique and one Guadeloupe.
1:48
But that doesn't mean that it must be true. Again there could be a possibility
1:53
where we see three voyages to Gaudeloupe that we just haven't drawn out yet. And again
1:59
we know that having a destination appear three times is clearly a
2:03
possibility. So again we're not going to eliminate (C). Moving to D:
2:07
Freedom makes and most two voyages to Jamaica and
2:13
again we made that deduction in our general setup. Jamaica is maximum going to show up
2:18
twice because of the condition that any time we have Jamaica we must have
2:23
Guadalupe in the week immediately preceding it. So, if we had three Jamaicas we
2:29
would have to have 3 Guadaloupes in each week preceding each Jamaica which is six
2:36
of the seven weeks but we still have to place M and T which clearly does not
2:41
follow. So (D) must be true and (D) would be the correct answer. And again a great example
2:47
of a time trap questions that they're trying to get you to have to go through
2:51
all of these answer choices and check them one at a time and proving that something
2:56
must be true is extremely difficult as you have to show that it's the case in
2:59
every single possible scenario. So again that's why we quickly scan the answer choices looking
3:05
for counter examples from previous work that can eliminate answer choices because they're
3:09
not necessarily true and also looking for any of the major deductions that we
3:13
made like answer choice (D) here that Freedom can make at most two Voyages to Jamaica.
3:20
That is the end of our discussion of the third game. Let's turn our attention now
3:24
to the fourth game of the June 2007 LSAT.
