#7 - Local, Must Be True

Complete Question Explanation
(The complete setup for this game can be found here: lsat/viewtopic.php?t=15716)

The correct answer choice is (D)

The condition in the question stem asserts that both an N and a G film will be shown, and that information in combination with the super-rule creates the following relationship:

Because of the size of the block behind N, the first N cannot be shown in any of the last three slots. From the Not Laws, we also know that N cannot be shown on day 2, and hence the only days remaining for the first N to be shown are day 1 and day 3. Therefore, answer choice (D) is correct.

The answer listed for this question is (D) day 1 or else day 3.

But how would the rule fit into day 1?

If N>GIN, and N went into day 1, N would also have to go into day 4 which would violate the Super rule, wouldn't it?

Hi Melissa,

Thanks for the question. As you note, the correct answer is indeed (D). Let's take a closer look at why that is the case.

First, you are right that we have a N > GIN super-rule in play in this question. But, when considering whether N could be shown on day 1, it looks like you interpreted it it as a NGIN block (forcing N to be shown on day 4, which would be a violation). But, that doesn't have to be the case since the "GIN" portion is a separate piece from the initial N. Thus, N could be first, but then the GIN block could be in a position other than 2-3-4, avoiding the violation you mention.

Please let me know if that makes sense. Thanks!

Yes absolutely, thank you so much!

I am confused with the phrasing of this question. From the answer key in the back of the homework section (in the book), it seems like the question was only referring to the first Norwegian film (in the following chain: N > GIN). How come the question is ignoring the placement of the second Norwegian film?

Because, if the first Norwegian film is placed in the first section, then it is possible for the second Norwegian to be in the fifth day. So, that would make 5th day possible (answer choice E), right?

Hi Blue,

The key to this question is seeing that it is a Must Be True question, so while N can be shown on day 5, it's not the case that N must be shown on day 5, which figures into these answers. For example, the following hypothetical is possible—N-F-H-G-I-N—which shows that N doesn't have to be on day 3 or else day 5.

In this problem, answer choices (A), (B), and (C) are relatively easy to work with, but (D) and (E) are much trickier because they pose scenarios where N is claimed to be limited to at least one of the pair of days. So, if we can show one day doesn't have to occur, that's not enough to eliminate these answers; we have to show that both days are out. Our hypothetical does that for (E), knocking it out.

Please let me know if that helps. Thanks!

Thanks Dave! Yes, I understand it now!!

Question #7: Local, Must Be True. The correct answer choice is (D)
The condition in the question stem asserts that both an N and a G film will be shown, and that
information in combination with the super-rule creates the following relationship:
N G I N
Because of the size of the block behind N, the first N cannot be shown in any of the last three
slots. From the Not Laws, we also know that N cannot be shown on day 2, and hence the only days
remaining for the first N to be shown are day 1 and day 3. Therefore, answer choice (D) is correct.

I do not understand, if we are considering the size of the block behind N, then how is it possible that N can be in day 1 what about the block behind it (G,I)

There is some additional discussion of this question in this thread, Naj:

The short answer here is that there is an N somewhere before a GIN block. They do not have to be adjacent - the first N could be in the first space, and the GIN block could occupy slots 4, 5, and 6, for example. That setup alone proves that there does not have to be an N in slot 5, eliminating answer C.

To clarify, when we say the GIN block is behind N, we mean it comes after N in the order, like this:

N GIN

That first N must be either in slot 1 or else slot 3, and that's answer D.

I hope that helps! If not, try drawing it out and see if you can come up with a solution where there is no N in either slot 1 or slot 3, but still complying with all the rules. I think you'll find you cannot do so, proving that an N must be in one of those slots.

Hi,I've been wondering how I can know that it's only THE FIRST N that this question asks here given the way the question is rephrased.(The question is " If a film in Greek is going to be shown at some time after a film in Norwegian, then a film in Norwegian must be shown on" and nothing about whether or not it's only the first or including both mentioned, while explanation says "hence the only days remaining for the first N to be shown are day 1 and day 3". )
Or, is it the case that regardless of how the explanation is rephrased, D is correct because it is only D that can be "Must be true' among all the answer choices here? (and my question above is not something that one should particularly care...?)

Could you help me with this? Thank you!
