Explanation:

1. The word "submarine" breaks down to "sub-" (under) + "marine" (related to the sea), so the prefix means under.
2. "Melancholy" is defined as a feeling of persistent sadness, so its best synonym is sad.
3. "Dark" is an adjective, and adding "-ness" creates "Darkness", a noun. The other options either use the wrong suffix or change word type incorrectly.
4. A colon is used to introduce a list after an independent clause. The correct format places a colon right after the introductory clause, no extra space before it, and lists items clearly.
5. A semicolon joins two independent clauses or separates clauses with a conjunctive adverb like "however". It should come before the conjunctive adverb, with a comma after it.
6. A compound modifier (two words describing a noun) needs a hyphen when it comes before the noun. "Well-known" correctly hyphenates the modifier before "actor".
7. A non-restrictive relative clause (providing extra, non-essential info) needs commas around it. The clause "who lives in New York" is extra info about "My brother", so commas enclose it and separate it from the main clause.
