#23 - Local, Could Be True

[Administrator]

Complete Question Explanation
(The complete setup for this game can be found here: lsat/viewtopic.php?f=107&t=7219)

The correct answer choice is (A)

If Z2 includes an H subzone, then according to the fourth rule of the game, Z2 does not include an I subzone:

In addition, this question stem establishes that there are a total of 3 R subzones. In compliance with the first rule, none of these subzones can be added to Z1. Additionally, at most one R can be added to Z2 (third rule). Therefore, either all three R subzones will be added to Z3, or else two of them will be added to Z3, and one—to Z2:

Finally, recall that no more than one R subzone is allowed in any zone containing an H subzone (third rule). From this we can infer that Z3 cannot contain an H subzone:

The setups above are sufficient to eliminate every answer choice except for answer choice (A), which could be true and is therefore correct.

The wording of the question sterm was a bit confusing while I worked on it.

I pretented "in all" was absent, and thought RRR spreads somewhere in different zones. (2 and 3)

However, while the entire rules and questions were confusing in regard with their language, I was not sure whether Q23 was meant RRR in one zone or what.

Does it make any difference if the question stem omits "in all" ?

reop,

"In all" just means that there are exactly three subzones for retail use somewhere, not necessarily all in one zone. As Z1 cannot have these, they must be spread among Z2 and Z3; but since Z2 has a subzone for housing, it can't have more than 1 of the 3 retail.

You are still expected to place the remaining 2 Hs and 3Is right?

Nope! There is no requirement that all 9 variables be used. This question is just about what could happen, and while we could use more variables, we don't have to. A perfectly acceptable solution to this question would be:

Zone 1: empty
Zone 2: H
Zone 3: RRR
