Studying for the LSAT / Explanation of PT 55, Game 2
« on: December 05, 2008, 11:35:14 AM »
This game is annoying because of the multiple possibilities, but it's really not so bad.. Aren't they hip, using e-mail in the topic? Next thing you know, they'll be mentioning Facebook, MySpace, and text messages.

Game 2:

Basically, we have either 4, 5, or 6 slots. So your templates would be:

_ _ _ _    in this template, it would be HJLH or JLHJ because we can't have LHJL (L can't be first), and first and last must be the same.

_ _ _ _ _

_ _ _ _ _ _

there are too many possibilities to draw out in the 5 and 6 slot templates. just remember to write the not-laws that L can't be first or last in each.

abstractions of the rules:

1 - HJ (horizontal block)

J is 1/2/3

L not last

1 <--> last

question 7:

pick through it using the rules one at a time. straightforward - each choice except D violates a rule.

question 8:
when they say "maximum," that means we should create a 6-slot template.

the key is to remember that we can only have 1 or 2 of each letter, so J and H are closer than you'd think - we get JLLHHJ

there are only 2 spaces between the first J and the first H - answer C

question 9:

go back to the beginning where I wrote the two layouts for the 4-slot option: HJLH or JLHJ

what must be true is A - we only have 1 "L" in each scenario

B- could be true, not a must
C-could be true, not a must
D- could be true, not a must
E-could be true, not a must

the key here is to look at both possible layouts

question 10:
E - because L cannot be 1st,it can't be last. if there is a 6th one, the 6th one must be the final one.

question 11:
if the 5th is from L:

A-the 1st cannot be from J, because then the 6th would be from J. this prevents us having an HJ block because we can't have 3 Js.
B-2nd can't be from L because that leads us to HLHJLH - 3 Hs are not permitted
C-3rd can't be H because we can't fit the HJ block without making 3 of something
D- 4th from J. We get HJLJLH - answer - satisfies all conditions
E-6th from L is not permitted (see previous question, and original rule - L can't be first, so it can't be last

question 12:
First try the 6 slot diagram with maximum spacing: _ L _ _ L _

however, we can't fit an HJ block except in slots 3/4, which means that there would be a 3rd slot of something, so try them closer together

HJLJLH works, but there's only one space

I'd go on to the 5-slot diagram, but since L can't be 5th in this diagram, I get

_ L _ L _   - only one space between them again, and I know that HJLJLH works, so there's only one space - the answer is B.

7. D
8. C
9. A
10. E
11. D
12. B

Studying for the LSAT / Explanation of PT 55, Game 4, Question 23
« on: December 03, 2008, 11:49:04 PM »
One of my students had a question about question 23 of the logic games section of PT 55. here is my explanation in case anyone else is interested.


"In the logic games for number 23, I got A. That is the only one that I got wrong. Let me know what you think."


The answer to 23 is D. Here's the layout of the scenario that proves it:

1 2 3 4

(A) is wrong because G is on board when the van reaches F, as you see above.

(B) J is on board when the van reaches M, as you see above.

(C) R is still on board when the van reaches F, as you see above.

(D) is the answer because V has already left when the van reaches F. It's impossible to create a scenario where V is grouped with F or V is after F.

(E) the diagram above shows that V is with M.

The game's overall setup

_ _ _ _ FLMS
_ _ _ _ GJRV
1 2 3 4

Abstractions of the rules

L is on 1 or 2 - straightforward rule

V > J - straightforward rule

MR as a vertical block, or M > R. We can never have R > M.

FJ as a vertical block or F > J, either of which cause a GS vertical block or an S > ordering

Alternatively, if we have J > F, then we have G > S.

This game is a bit different from the ones in previous exams. The rules are a bit twisted, but if you got everything else in the game right, then I'm sure you understood the two main possibilities for the final rule regarding F, J, G, S.

Oh Hai, I forgot to READ THE RULES, so the mod replaced my ad with a lolcat!
