Question

1. which sentence is punctuated correctly? we wanted to watch a movie; so the power went out. we wanted to watch a movie however; the power went out. we wanted to watch a movie; however, the power went out. we wanted; to watch a movie the power went out.

Explanation:

1. "We wanted to watch a movie; so the power went out." - The use of "so" after a semicolon is incorrect. "So" is a coordinating - conjunction and doesn't follow a semicolon.
2. "We wanted to watch a movie however; the power went out." - "However" is a conjunctive adverb and should have a comma after it when used to connect two independent clauses, not a semicolon immediately after it.
3. "We wanted to watch a movie; however, the power went out." - This is correct. A semicolon is used to separate two independent clauses, and "however" is properly set off by commas.
4. "We wanted; to watch a movie the power went out." - The semicolon is mis - placed. It should separate independent clauses, not break up the verb phrase "wanted to watch".

Answer:

We wanted to watch a movie; however, the power went out.
