A gramma question !!!!!! need help !!!

<p>Can anyone explain the following question for me? Thanks a lot!!!</p>

<p>The people(sitting behind me) in the movie theater were talking throughout the film (and would) not keep (their voice) down even after being asked to do so.</p>

<p>The answer: C.
why? Is that mean voice here is a countable noun? I thought voice should be uncountable~</p>

<p>What about "noice" ? Is it also countable?</p>

<p>It’s “would not keep their voiceS down” because each person has a voice!! When you say “noice”, you mean “noise” right?? If so, the word “noise” can be put in its plural form and becomes “noises” as in “I hear a lot of different noises coming through the door.”</p>

<p>Thanks. I really didn’t know that voice and noise have plural form. Thank you very much!
You are gonna take the Oct. Text? Good luck! I guess you can get at least 2300~~~</p>

<p>^^^^^^</p>

<p>Now that is ■■■■■■■■…</p>

<p>Yeah! I’m taking the SATs on the 9th too… Stressful period, no?? About the 2300… Really can’t say… I hope I’ll at least get well over 2100 otherwise I’m in big trouble for the colleges I’m applying to!!!
BEST OF LUCK!!!</p>
