To identify the type of error in each sentence, we need to analyze and understand the grammatical rules associated with each error category. Let's go through each sentence and determine the error type.

1. A giant monster attacked the warehouse yesterday morning the warehouse makes sneakers.
Error type: Sentence fragment
Explanation: This sentence is missing a subject or a verb in the second part of the sentence, making it a fragment.

2. At 3 p.m. I will be feeding the ducks. At the park.
Error type: Run-on sentence
Explanation: The second sentence, "At the park," is not properly connected to the first sentence, resulting in a run-on sentence.

Explanation: The subject "they" requires the corresponding plural verb form "are" instead of "is."
