Q18

[mitrakhanom1]

I wanted to know why A is the correct answer. I put B as my answer choice for the following reasons:

I interpreted the question to mean what goes in each day of the week. So, If the operation division goes on tuesday, it has to go on wednesday too. since the conditional statement says what is toured on tuesday is also toured on wednesday. which means P has to go monday and the SS chunk has to go thursday and friday.

P O O S S
M T W TH F

Please let me know what i'm doing wrong. thanks

You came up with one possible scenario that satisfies the condition that Tues = Wed.

But as you no doubt saw with your one scenario, that would make (A), (B), and (D) correct.

With must be true questions, we need to assess ALL possible scenarios.

So we need to ask ourselves:

What if Tues/Wed = P
What if Tues/Wed = S
What if Tues/Wed = O

Well, the first one won't work, because P can't be Wed.

You handled the 3rd one.

If Tues/Wed = O, we get
P O O S S

What about the 2nd one?

If Tues/Wed = S, we get
_ S S _ _

Do we know anything about Mon/Thu/Fri?

Mon has to be P, because O can't go there.

P S S _ _

The last two days could finish either way:
P S S O P
P S S P O

In total, we have these three possible scenarios:
P O O S S
P S S O P
P S S P O

Since we want something that must be true in all three scenarios, we can just look vertically for anything that's the same in all 3 cases.

Turns out that P is always first, so (A) is our answer.

(B) doesn't have to be true, since P S S O P and P S S P O are okay
(C) doesn't have to be true, since P O O S S is possible
(D) doesn't have to be true, since P S S O P and P S S P O are okay
(E) doesn't have to be true, since P O O S S and P S S P O are okay

Hope this helps.
