re·frain ri-frayn

1. (verb) to resist doing something
2. (noun) the chorus of a musical piece

which sentence uses refrain as a noun?
○ the flight attendant requested that the passengers refrain from smoking.
○ students should refrain from using their cell phones during the lecture.
○ experienced audience members refrain from clapping until the end.
○ the haunting refrain stayed with the audience long after the show ended.

Explanation:

To determine which sentence uses "refrain" as a noun, we analyze the dictionary entry: the noun definition is "the chorus of a musical piece". Now check each option:

• First three options use "refrain" as a verb (to resist doing something), as they follow the verb structure (subject + refrain from + action).
• The last option, "The haunting refrain stayed with the audience long after the show ended", uses "refrain" as a noun (referring to the chorus of a musical piece, fitting the noun definition).

Answer:

D. The haunting refrain stayed with the audience long after the show ended. (assuming the last option is D; if options are labeled differently, adjust the label but the text remains the same)
