Select the word or phrase that makes this sentence grammatically correct: Theo was in great shape; he ___ all the way back to the pier.
Correct answer
A
Rationale
In this sentence, the correct past tense form of the verb 'swim' is 'swam.' 'Swimmed' (Choice B) is not a valid past tense form of the verb. 'Swum' (Choice C) is the past participle form of 'swim' and does not fit in this context. 'Swim' (Choice D) is the base form of the verb and does not convey the past action correctly. Therefore, the correct choice is 'swam,' indicating that Theo already completed the action of swimming back to the pier in the past.
