<p>All the talk about controlling noise, keeping rivers
clean, and planting trees:________: about major
changes in laws and lifestyles</p>
<p>(A) have not impressed people enough to be bringing
(B) have not made enough of an impression on people
to bring
(C) have not made people impressed enough to bring
(D) has not impressed people enough to bring
(E) has not made enough people impressed for

<p>What really threw me off was the subject of the sentence... isn't the word "all" usually supposed to be plural? or is all even the subject in the sentence.</p>
<p>“All the talk about…trees” is the subject. Prepositional phrases don’t matters, so the cut-down subject is “All the talk,” which is singular. You wouldn’t say “All the talk are…”</p>
<p>it definitely sounds better with “is”, but how do u know that “all the talk” is singular? the word “all” can be used as both a singular and a plural subject rite?</p>
