Fill in the blank with the correct form of tense: Every Monday, Sally ________…

Concept: Habitual actions repeated at regular intervals (signalled by words like "every Monday", "always", "usually") are expressed using the Simple Present Tense. For a third-person singular subject (he/she/it, or a singular name like Sally), the verb takes an -s/-es ending: base verb + -s/-es.

Application: The subject "Sally" is third-person singular, and "Every Monday" marks a habitual, repeated action. Applying the rule, the base verb "drive" takes the third-person singular ending, giving "drives".

Cross-check: Testing the remaining forms against the same time marker confirms none of them fit:

• "Has driven" — present perfect tense, used for a past action linked to the present or a recently completed action, not a habitual/repeated one.

• "Is Drive" — not a valid English verb form; the progressive aspect requires "is" + verb-ing (e.g., "is driving"), not "is" + base form.

• "Drove" — simple past tense, marking a single completed action in the past, which contradicts the repeated, ongoing nature of "every Monday".

"Drives" is the only form that satisfies both the tense (simple present) and the subject-verb agreement (third-person singular) required by the sentence.
