In each of the following questions, choose the option that best completes the gap(s). The teacher asked the students to submit their assignments before the ...

The sentence "The teacher asked the students to submit their assignments before the end of ______ week" describes a teacher setting a deadline for assignment submission. The blank requires a determiner that specifies which week the teacher means.

The correct answer is next. "Before the end of next week" establishes a definite, upcoming deadline that students can work toward. Since the teacher is giving an instruction about future action (submitting assignments), a forward-looking time reference is needed.

The other options do not fit:

• "Last" refers to the previous week, making the deadline already past. A teacher cannot instruct students to submit work before a deadline that has already expired.
• "Any" is too vague and indefinite to serve as a meaningful deadline. A submission instruction requires a specific timeframe.
• "These" is a plural demonstrative pronoun and does not agree with the singular noun "week." The correct singular form would be "this," but that is not among the options.
