J is scheduled for the 3rd day.
According to rule3, we can get two templates:

G, _, J, _, S, _, _ & _, G, J, _, S, _

then, from rule1 & rule2, we can put H & U into the two templates:

G, _, J, S, H/U, U/H & _, G, J, H, S, U

Finally, put T:

G, T, J, S, H/U, U/H & T, G, J, H, S, U

the question asks "could be true", so (C) is correct.

Thanks for your posts!

This game is about as good a candidate for framing as you'll ever see. Given that the second and third constraints combine to give us G_ _ S-U, and that the last constraint tells us that J is either first or third, we have good reason to suspect that the possible setups are very restricted. Indeed, whether we start by investigating J or the G_ _S-U chunk, it really breaks down into three frames (interchangeable elements are in italics):

T G J H S U
1 2 3 4 5 6

G T J S H U
1 2 3 4 5 6

J G T H S U
1 2 3 4 5 6

Since question 5 tells us that J is on day 3, we know we're dealing with our first two frames.

(C) is correct because in our second frame, H could come later than U. The other answer choices must all be false according to our frames.

Does that answer your question?

By three days after, would it be diagrammed
G _ _ _ S

or

G _ _ S.

I'm confused. It would be helpful if someone could show me why it is one way and not the other.

Thanks.

It's

G_ _S

You can verify this by looking at the first question

if J is first, then G must be second, S must be fifth, and by the second rule, U would have to consequently be 6th.

If it was G_ _ _S then there would be no room for "U" in the first question since S would have to be 6th and U has to come after S but it can't because all the slots would be filled up.

Also, it would be much too constraining if it was the other way -- in fact, the whole game would be solved if it was G_ _ _S because G would have to be 1st, J 3rd, S 5th, U 6th, H 4th, and T would take up the 2nd slot. This would be the only configuration possible and a logic game is never that easy.

Hey Guys,

Yeah, it's very easy to make a mistake about the whole "Three days later" thing. What that means it that there will be two blank slots, and the third spot will then be filled.

It can also help to think of it in real terms.

What number is three greater than 4? It's 7.

4 5 6 7

Notice there are only two numbers between 4 and 7.

What day is three days after Monday? It's Thursday.

Monday Tuesday Wednesday Thursday

Notice there are only two days between Monday and Thursday.

Never be afraid to do little things like this on the actual test. It's way better to spend 15 seconds proving something for sure, then spending 4 minutes with a bad diagram!
