But D starts with "whose" which is a possessive pronoun. I think it's wrongly used here in option D & E.

My money is on B.
Thanks,

Hi All,

It looks like most of the posters in this thread are probably long gone (2007 was quite awhile ago).

This SC provides a great "context clue" that helps to eliminate many of the wrong answers: "the city has PROPOSED... a number of... projects..." This means that the projects have NOT happened yet (they've just been proposed), so any impact/effect that these projects may have will be in the FUTURE (thus the projects...WILL raise water bills). Eliminate A, B and C.

Between D and E, D properly uses the idiom "so high that..." Eliminate E.

Final Answer: D
