Error in Preptest 43 Section 4 Question 18 (Logic Games)

The right answer is (D) Y and Z only. But I think the correct answer could be (C) X, Y, and Z.
I re-read this stem a few times and cannot see why (D) is the right choice.
Thank you for your help!

the second rules states:
"The falafel truck serves exactly two of the office buildings."

Yup! So the falafel truck can serve X and Y OR Y and Z. Therefore, the falafel truck can serve X, Y, and Z--not simultaneously, but has the potential to serve all X, Y, and Z.
Why do you rule out X?

You're misunderstanding the question stem. It's not asking for a complete list of office buildings "any one of which" could be served.
They're just asking for a partial valid hypothetical.

Are there any errors in LR or RC?
If so, what are they? Where can I find the corrections?
Thank you!

there are withdrawn questions scattered about. off the top of my head, there is an RC question in the early 50s that was withdrawn.
