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

1:06

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.
