Q4

[theonlyrij]

Hi,

I got this question right but it was by guessing. Can you please explain to me how Yansky cannot be at 5?

In my understanding, why couldn't you have:
SURWYT

In that order Yansky is in position 5.

Also, am I right to think that U-R can be separated in the line. For example: SUWYRT?

Thanks!

It looks like you overlooked the new condition in the question, which is that P is going to meet with S the hour before she meets with Y. So you have to have an SY block in your order.

The constraint we are going to work with first is:

S--WY/YW--T (This is a big chunk--S has to go sometime before the YW or WY twosome--remember Y and W have to be side by side--and T has to go sometime after it.)

Q4 tells us that Y is immediately after S, which means we'll have the chunk:

SYW--T

Then we have the U--R relative rule to deal with (which yes, means R comes after U but doesn't have to come RIGHT after U--so you're hypothetical of SUWYRT is correct outside this question--inside this question, Y has to come right after S).

We see that Y has to have at least 2 letters that come after it--which means it can't be fifth.

Let me know if you have any more questions!

I understand why Y can't meet at 5, but I'm wondering moreso about what is the best approach to this question once you figure out the SYW-T string.

Is trial end error through each answer choice the best strategy or is their a faster way?

There is a fast way! What is great about this game is that there are ZERO not rules. We do not have to worry about a certain slot forbidding the placement of one of the variables.

So, with a question like this, you correctly inferred SYW - T.

But also include what else you know! U - R

So we have two tree diagrams that do not intersect.

SYW - T

U - R

Let us go into the answer choices to correctly answer what MUST BE FALSE.

A) Could R be at 2? Sure! No need to even check it! Put U first, then R second, and then let the other variables follow in sequence as they are. With there being zero not rules, we are only concerned about the ordering!

B) Could Y be at 3? Sure! It would require putting U first, then letting the SYW block follow to have Y 3rd.

This is all about seeing it with your mind.

C) Could T be at 4? Sure, put U and R at the end.

D) No way! Must be false, this is our answer. Y at 5 would place T 7th, which is impossible!

E) Could T be last? Sure, put U and R at the very beginning.

Great breakdown!
