#12 - Local, Cannot Be True

[Dave Killoran]

Complete Question Explanation
(The complete setup for this game can be found here: lsat/viewtopic.php?t=1753)

The correct answer choice is (E)

The information in the “if” statement can be diagrammed as follows:

From the fifth rule, M is in exactly one detection area. Thus, when M is in T, M cannot be in R, S, or U. From the fourth rule, L cannot be in any area that M is in, and so L cannot be in area T. Additionally, because any plane in area U is also in area T, because L cannot be in area T then it also cannot be in area U (and hence the L Not Law on area U). This is essentially a result of the contrapositive of the U T area relationship.

L is now limited to areas R and S, and because the game scenario specifies that R does not intersect S, no plane can simultaneously be in both areas R and S. Thus, L can be in only one detection area (R or S), and answer choice (E) cannot be true and is correct.

Remember, this is a Cannot Be True question, and thus the four incorrect answer choices could occur. For example, answer choice (D) could be true because K could be in both areas R and T.

Could someone help me with something. I did this game using the circle for the zones. If M can be in the the part of T that’s not touching R,U, or S, (because it represents 1 area which I understand) then why can’t L be put in either R and T or S and T? M is not touching R and T or S and T, it’s only touching T. Am I just overthinking this? (Which I tend to do lol)

Oh and one more thing to add on this comment. Since it is the case that L can’t got into R and T or S and T because it would overlap with T violating rule # 4, then why can M in general go into R or S without violating rule # 5? They overlap T as well. Does it have to do with the fact that parts of R and S are not touching at all? I know that’s a lot, thanks in advance for any advice .

ltowns,

To your first post, that would violate the 4th rule. M is in T, so L cannot be in T. In your hypothetical, you imagined L as in R and T or S and T. But then L is in area T in both your examples. That violates the 4th rule.

To your second post, R and T overlap, but it's certainly possible for something to be within R but not T, or T but not R. Otherwise, R and T would just be the same zone, completely destroying the distinction between overlap and complete coincidence.

Thanks so much for your explanation. I also forgot this game was in the LG Bible, I'm gonna take a look at that for more clarity with this game as well. Thanks.
