Moving on to question 13. If freedom make a voyage to Trinidad in week 5 which one of the
0:12
following could be true?
0:14
Alright, so let's draw out a quick hypothetical. It tells us that we have Trinidad in week 5
0:20
and we already know we have Trinidad in week seven. So, now it's important to know with 5
0:27
being Trinidad we've lost the option of 4 and 5, 5 and 6, for our Guadalupe Jamaica block which
0:36
we know we're gonna have at least one of. So, now our only possibilities here are
0:40
1 & 2, and 2 & 3 which obviously means we're only going to be going to Jamaica once
0:45
because we don't have room for two of them because again we know that Jamaica
0:48
cannot be fouth and also can't be first. So, again either having Guadalupe Jamaica 1
0:56
and 2 or having Guadalupe and Jamaica 2 and 3. Now the only thing remaining here is
1:04
our Martinique
1:06
box. Again we know we have too Martiniques and there must be at least one Guadalupe
1:13
in between them. So we know in this scenario this is the only possibility. In
1:19
the top scenario now we have to place our two Martiniques and there must be
1:25
at least one Guadalupe in between. Well we already have a Guadalupe in 2 so regardless
1:30
of where we place our Martiniques that condition is going to be
1:33
satisfied. Obviously we can't go 4 & 6 though. So you notice it's either going to be 1 &
1:38
4 or its gonna be 1 & 6 which means no matter what we're going to have
1:42
a Martinique appear first.
1:45
Now we can have either Martinique show up 4th or 6th and the other variable can only
1:55
be Guadalupe because we can't have Trinidad back-to-back so we can't have Trinidad 4th or 6th.
2:02
We can't have have Jamaica show up again because of our fourth condition and there's no room
2:08
for Guadalupe and we already know that Martinique shows up exactly twice. So, when
2:13
we place that Martinique the other is gonna have to be Guadalupe. So, again
2:18
we're gonna have these reverse dual options of
2:21
Martinique and Guadeloupe. Alright, so now turning our attention to the answer
2:27
choices. Here again looking for what could be true.
2:30
(A) Freedom make a voyage to Trinidad in week 1 and that is not possible. It's
2:35
either going to be Martinique or Guadeloupe. (B) Freedom make a voyage to Martinique in week
2:40
2. Again inpossible. It's either going to be Guadeloupe or Jamaica. (C) Freedom makes a voyage to Guadalupe in week 3. Again,
2:49
not possible. Either Jamaica or Martinique which brings us to (D) Freedom makes a voyage to Martinique in week 4.
2:56
And you noticed in our top scenario we could have a voyage to Martinique in week
3:02
4. So, (D) here would be the correct answer. And again just checking (E) to show you
3:08
Freedom makes the voyage to Jamaica in week 6 and again you notice it's either
3:13
going to be Guadaloupe or Martinique so (E)
3:16
cannot be true in (E) is out.
