Here is the item:
Although Leroy has read travel books about every exotic country imaginable, he refuses to 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 where he does not know the language.

The second verb, might be stinged, is the problem. As you know, the verb requires the past participle because of the auxiliary verbs might and be. Might be stung is the correct form.
