Logic game: Seven Houses on a Street

The question states Newmans live immediately west of the Kahns, which one of the following statements must be false?

One of the conditions is the Muirs lives next to Kahns. So that tells me that M and K can either be MK or KM. If I add the new rule above it should look like this NKM. So my line-up from West to East looks like this:

LPNKMRO

Answer choices A, C, D and E all are appear to be false. Please explain why A is the right answer and the others aren't. Is my set-up incorrect?

Thank you.

Thanks for the question, mrueda08!

I'm afraid it appears you have misinterpreted the fourth rule of the game. Since P is east of K and M, but west of L, this would be something like:

(K/M) -- P -- L

It's very easy to get flipped on a rule when the 'sides' are east and west instead of earlier/later! This is a great reminder to label the sides of your diagram when dealing with something other than strict numerical ordering. Once you rewrite that rule, the rest should fall into place.

Since N is to the west of K, M must be immediately to the east. P and L must take up the last two eastern spots, then, respectively. Only the two westernmost spots remain for R and O, and we know that R cannot be on the end. Therefore O must be in the spot furthest west, while R takes the second spot from the west.

Here's a diagram so that you can double check!
