Question

fix any punctuation or capitalization errors below. click \submit answer\ if there are none.
cho chang saw an advertisement for a discounted television; the sale had already ended, however.

Explanation:

The original sentence has a capitalization error after the semicolon. After a semicolon, the next word should not be capitalized unless it's a proper noun. Here, "The" after the semicolon should be lowercase "the" because it's not a proper noun and the semicolon connects two independent clauses, not starting a new sentence with a capitalized word in this context. Also, the punctuation for "however" is correct as it's used as a conjunctive adverb at the end of the second clause with a comma before it. So we correct the capitalization of "The" to "the".

Cho Chang saw an advertisement for a discounted television; the sale had already ended, however.
