My teacher asked me to keep _____.

quiet

The most appropriate option to fill in the blank is quiet.

The word "quiet" means to be silent or not make a noise. It is the most appropriate word to use in this context, as it conveys the meaning of the teacher asking the student to be silent.

The other options are not as appropriate.

• Quite means to a moderate or satisfactory degree. This is not the right word to use, as it does not make sense to say that the teacher asked the student to be quite.
• Quit means to stop doing something. This is not the right word to use, as it does not make sense to say that the teacher asked the student to quit.
• Quaint means old-fashioned or charming in a slightly old-fashioned way. This is not the right word to use, as it does not make sense to say that the teacher asked the student to be quaint.
