Answer:
Sentence 4
Explanation:
"We are going to be leaving soon," he said, "so get your shoes on."
This sentence is capitalized correctly. There is a captital letter in the first word of the sentence but there are no more capital letters because the sentence finishes in the quotation marks. if you’re quoting a complete sentence the first letter is capitalized but not capitalized if you’re quoting a fragment, as is the case here.
