Question

Identify the sentence with the correct verb. A. I​ can't believe he has swum to the island. B. I​ can't believe he has swaum to the island. C. I​ can't believe he has swim to the island. D. I​ can't believe he has swam to the island.

Answer 1

The correct answer is "I can't believe he has swum to the island." Swum is the past principle of "swim." However, if you drop the word has the answer would be D and the sentence would appear much more grammatically appealing. :)
