#19 - Global, Must Be True

[Administrator]

Complete Question Explanation
(The complete setup for this game can be found here: https://forum.powerscore.com/lsat/viewtopic.php?t=3901)

The correct answer choice is (A)

This is a very difficult question, and it trades on one of the inferences we referenced would be discussed in the questions. Note that the question stem wording is important—“must perform earlier than 10” means that we need to identify the group that can only perform at 6 or 8.

As discussed in the setup, from the second rule G cannot work at 12. Thus, G is a strong candidate to also be unable to perform at 10. During the test, the best approach would be to make a hypothetical with G performing at 10 and observe the consequences.

When G performs at 10, then from the second rule H must perform at 12, and from the first rule P must perform at 6:

The remaining groups to perform are L, Q, and T. Q cannot perform at 8 when P performs at 6 due to the actions of the last rule, and thus Q must perform at 10. However, G and Q cannot both perform at 10 due to the third rule. Thus, G cannot perform at 10 (and can only perform at 6 or 8), and answer choice (A) is correct.

Hello,

How come the order can't be as follows:

NORTH: P(6) T(8) G(10)
SOUTH: Q(8) L(10) H(12)

This would allow G before H.
Two folks at the 10 mark which doesn't violate the "no rock and folk at 10 rule"
Q is immediately preceded by a folk, which the stimulus allows to be separated by stages.
L and T are on separate stages.
P is in 6 which is one of its options.

What am I missing? It seems based on this analysis it is possible for G to perform at 10 rather than must be performing earlier than. I had to guess on this question because it was harder than the others but I am honestly so puzzled as to why this seems technically incorrect for a MBT question.

Can someone please reply? I would love to hear an explanation.

Thanks in advanced.

Actually, I think I have been staring at it for so long I think I see my error. I was getting so frustrated because I couldn't see it at first! I was looking at it in a continuous line from North at 6 to South at 12.

So if it were what I had diagrammed:

NORTH: P(6) T(8) G(10)
SOUTH: Q(8) L(10) H(12)

Then G isn't before Q how I was thinking in a "line way." It's actually P that's before Q because it's based on time and P is a rock, which is a violation. I'm hoping this is the correct reason as to why I initially could not see the problem.

Hi gavelgirl!

You are correct--the last rule tells us that "Query performs immediately after a folk group, though not necessarily on the same stage." So if Q performs at 8, then a folk group must perform at 6. P is the only group you have performing at 6 and it is a rock group, meaning there is no folk group immediately before Q. Therefore, that hypothetical violates the last rule and is not possible.

Hope this helps!

Best,
Kelsey
