Fill in the blank in the following sentence with the most appropriate option:
Do you know any man who doesn’t ______ to own a Château?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → want
Base form after do / does / did:
- After the helping verb do, does or did (and their negatives don't, doesn't, didn't), the main verb is always in its base form.
- The "-s" of the third person singular is already carried by does, so the main verb takes no "-s": doesn't want, not doesn't wants.
- Deciding clue: the helping verb "doesn't" just before the blank.
- Two-step check: 1. form after "doesn't" → base form only (want); 2. meaning: "want" is a state verb, so no continuous form.
- This sentence: "any man who doesn't want to own a Château".
- Complete sentence: Do you know any man who doesn't want to own a Château?
Example: She doesn't like cold coffee.
Why the Other Options are Incorrect?
Option 2: are wanting — Incorrect. "Are wanting" is a present continuous form; it cannot follow "doesn't", and "are" does not agree with the singular "man". (Want is also seldom used in the continuous.)
Option 3: has been wanting — Incorrect. "Has been wanting" is the present perfect continuous; a full tense form cannot follow the helping verb "doesn't".
Example: He has been waiting since morning.
Option 4: wants — Incorrect. "Wants" is the third person singular form; after "doesn't" the "-s" would be marked twice.
Example: She wants a new phone.
Contrast: after the helping verb "doesn't" the verb takes the base form (doesn't want); without a helping verb the third person singular takes "-s" (he wants).
