We couldn’t afford to keep our car, so we ……….. it.
Correct answer: A
The first clause has the subject “I” (first person singular), the auxiliary verb “can’t” is divided in the past form, into “couldn’t”, the main verb “afford” follows the auxiliary. The verb should be in the infinitive. A sentence with two clauses connected by the conjunction “so”.
⇒ The second clause has the subject “we” (first person plural), the verb “sell” is conjugated in the past form, becoming “sold” (this is an irregular verb)
We couldn’t afford to keep our car, so we sold it.
