PrepTest 10, Section 2, Game 1 (Q1-5)

Postby mshouman » Thu Apr 15, 2010 8:16 pm

Hello everyone,

I was wondering if someone can help me with an inquiry I have in PrepTest 10, Section 2, Game 1 (Q1-5):

From the setup, I managed to obtain the following:

L < K < G < I
F < K < G < I
N < H < M < J < G < I

From this, I can see how I = 9 (highest score) and G = 8 (second-highest).

I can also see that H = (2 OR 3 OR 4 OR 5), because only one person (N) is definitely lower and only four (M, J, G, and I) are definitely greater than H. Thus, H is on level 2 or level 3.

I can also see that N = (1 OR 2 OR 3 OR 4), USING using similar reasoning. Thus, N is on level 2 or level 3.

However, when reviewing the solutions provided by Testmasters, the solutions conclusively list N and H as being in list 3.

Can someone please advise how they managed to conclude that?

Thank you kindly.

This is actually from PrepTest 10. N and H don't have to be in the level 3 class, as evidenced by question 4. This solution provides further proof:
1: I G J
2: M H N
3: K F L

Thanks very much, Cambridge LSAT! I have also corrected the PrepTest #.

Hi,

I've run into this PrepTest question again and I wanted to enquire about Question 4:

Setup:
Ranking from highest to lowest, I get two inequality chains:
    I < G < J < M < H < N
    I < G < K < F < L

Therefore, I can conclude the following general set up (leftmost is highest, rightmost is lowest):

I G (J/K) ___ ___ ___ ___ ___ (L/N)


Question 4:
The answer claims that if Kathy and Laura are known to be in Level 2, then the composition of each class can be completely determined. However, using the setup above, I can find three different compositions where Kathy and Laura are in Level 2:
    I G K J M H N F L
    I G K J M H F L N
    I G K J M H F N L

Where is my reasoning incorrect, please?

Many thanks.

From your second chain, it looks like you've misinterpreted the sixth rule. K precedes both F and L, but the ordering of F and L is left uncertain.

The answer to question 4 is C. Since M is in between J and H, M must also be in the level 2 class. This puts N in the level 3 class, and the only others who can be in the level 3 class are F and L.

Wow! I did misinterpret! How on earth did I miss that?! Guess that's a lesson for me on being more careful with reading instructions.

You're great, Cambridge - that's why I'm one of your regular customers :D

Cheers!
