Charlotte Perkins Gilman, a late nineteenth-century feminist, called for urban apartment houses including child-care facilities and clustered suburban houses including communal eating and social facilities.
A) including child-care facilities and clustered suburban houses including communal eating and social facilities
B) that included child-care facilities, and for clustered suburban houses to include communal eating and social facilities
C) with child-care facilities included and for clustered suburban houses to include communal eating and social facilities
D) that included child-care facilities and for clustered suburban houses with communal eating and social facilities
E) to include child-care facilities and for clustered suburban houses with communal eating and social facilities included

Explanation:

First, we can eliminate all the answer choices that use with communal eating and social facilities included or any other structure that follows this pattern:

preposition + noun + participle

This pattern is almost always wrong on the GMAT, and is certainly wrong in this question. This eliminates C) and E).

A) is ambiguous--is clustered suburban houses parallel with child-carfacilities or with urban apartment houses? We need to repeat for to be sure that clustered suburban houses is parallel with urban apartment houses.

Now we're left with B) and D).

Now, the only difference between B and D is the infinitive to include, which GMAT considers unidiomatic.

That leaves us with D).
