1. Subject-Verb Agreement: The subject of the sentence is "account," which is singular. The verb should be "listens," but it needs to be changed to the singular form, "listens."
2. Word Order: The sentence structure is currently in passive voice. To make it more active and clear, we should change the word order.
3. Prepositional Phrase: The prepositional phrase "of his amazing dream" is awkwardly placed. It's best to place it after the verb.
Here are a couple of ways to fix the sentence:
Option 1 (Active Voice):
> The abbess and reeve listen to an account of his amazing dream.
Option 2 (Passive Voice):
> An account of his amazing dream is listened to by the abbess and reeve.
Both options are grammatically correct, but Option 1 is more natural and easier to read.
