Take a look at the sentence again:
Leroy has read travel books about every
exotic country imaginable but refuses to ever visit in person. He worries
that he might be stinged by a poisonous
spider, bitten by a deadly snake, or convinced
to order pickled monkey brains at a restaurant because he doesn't understand
the language.
The second verb, might be stinged, is the problem. This verb requires the past participle because of the auxiliary verbs might and be. Might be stung is the correct form.
| Verb | Simple Present | Simple Past | Past Participle |
| sting | sting(s) | stung | stung |
Bitten, the verb you chose, is perfectly correct. Before you continue, review the rules for irregular verbs.
