Take a look at the sentence again:
In her dreams that night, Diana had __________ in a pool of warm cocoa;
when she awoke, the aroma of chocolate still tickled her nostrils.
The sentence requires the past participle of swim, an irregular verb. Swum is the past participle.
| Verb | Simple Present | Simple Past | Past Participle |
| swim | swim(s) | swam | swum |
