Answer :
Final answer:
The sentence "The ship was enormous, its mast was almost 40 feet high." suffers from a run-on sentence error, where two complete thoughts are incorrectly joined without proper punctuation.
Explanation:
The error in the sentence "The ship was enormous, its mast was almost 40 feet high." should be corrected as a run-on sentence. This type of error occurs when two or more complete sentences are not separated by any punctuation, making it difficult for the reader to understand the break in ideas. A simple way to correct this would be to add a period or a semicolon between the sentences or to use a conjunction. For example, "The ship was enormous; its mast was almost 40 feet high." or "The ship was enormous, and its mast was almost 40 feet high."
