While having a serious conversation about your relationship, your romantic partner stops midsentence and exclaims, "we are out of milk." your partner's comment is an example of?

Idiomatic expression

An idiomatic expression is an Informal English word whose meaning is different.

Like in the example "we are out of milk." Literally, it means that there is no more milk. If it is taken as an idiomatic expression, it would be taken differently, depending on the culture or the situation.

d. i assume the underlined word is "role." reformat if it isn't.

explanation:

role is closest to part because when replacing words, "playing a vital decision," "playing a vital activity," and "playing a vital dollar" don't make logical sense. the only meaningful choice is "playing a vital part."

this fits one of merriam-webster's definitions of role: "a function or part performed especially in a particular operation or process."
