1). How is Extended Stay Hotels considered singular?
2). How is the word "lights" which is in the prepositional phrase acting as the subject?
1. As
Doer01 mentioned, I think they're looking at
Extended Stay Hotels as a name. This is very strange, as a lot of hotels are categorized as "extended stay", in which case we'd definitely go plural. Maybe they've just set this (contrived) example up to drive home the overall message?
2. Here
neither acts as a pronoun, but the rules that apply to
some of,
any of,
most of... don't apply to
neither of (
neither of can be followed by only a plural noun). Neither of + plural noun takes a singular verb. Although this is changing rapidly, it is what you should apply on the GMAT.
