Question

It is important that the TOEFL office every applicant's registration.

• A. will confirm
• B. confirms
• C. confirm
• D. confirming

Hint:

Check which verb form agrees with the singular subject "office".

Answer 1

The Correct Option is B

This question checks subject-verb agreement inside the clause "that the TOEFL office ___ every applicant's registration."

1. will confirm: brings in a future-tense modal, but the sentence describes a routine duty performed by the office, not a specific future action, so this form is out of place.
2. confirms: matches the singular subject "office" with the "-s" ending used for third-person singular subjects in the simple present tense, which fits the routine, ongoing nature of the statement.
3. confirm: is the base form without the "-s", correct for plural subjects like "they confirm" or "offices confirm", but not for the singular "office".
4. confirming: is a participle form and needs a helping verb such as "is" to function as the main verb, so it cannot stand alone here.

Since "office" is singular and the sentence is a general statement of fact, the verb must carry the singular "-s" ending.

Let's summarize:

• Singular subjects take verbs ending in "-s" in the simple present tense.
• A bare form without "-s", a modal, or an "-ing" form each fail to match a singular subject in a plain present-tense statement.

The verb that agrees correctly is "confirms", confirming that option (b) is the answer.
