Q21

[yawhtsup]

can someone please help me on #21, i dont understand why "e" cant be the answer. i have plotted them out and it worked.

and also i am having a bit trouble on #22.

thank you

No problem!

For question 21, suppose you check answer choice (D) and it works. Then you check answer choice (E) and it works. When you checked answer choices (A), (B), and (C) it didn't work.

Now the question asks us to find the fastest ranking that J could have. So of the answer choices that work, which is fastest? Clearly, answer choice (D) is faster than answer choice (E), so (D) is correct.

For question 22, the correct answer can be proven from the 2nd and 5th constraints. F or G is first. K _ _ L

Thus the soonest L could go is 5th.

F K _ _ L
1 2 3 4 5

Does that help clear this one up?

yes i got it. thank you. i forget about the faster and fastest part . but i now understand it.

For #21, we are looking for the fastest ranking J could have when M --J. Answer E is the slowest among the choices and answer D is the correct answer:
(F/G) M H K J (G/F) L O

For #22, since 1) F/G is the first, and 2) K _ _ L; the best we can do with L is to have (F/G) K _ _ L. Therefore, L is ranked no faster than 5th.

is there a faster way to do this question because I can eliminate the first two answers based on past deductions but after that I plug and chug

[maryadkins]

That's how I did it, too. The good news is that if you're efficient about testing (C) and (D) it doesn't take too much time. The thing about plug and chugging is that it's not always awful if you keep an eye out for inferences as you're doing it. In this question, as I was testing (C) I realized that the K__ __ L chunk was going to be a problem and I'd have to put K before J. In (D) that happened to work.

Good question, keep it up!
