Answer:
B. The meeting was only supposed to be for an hour; however, it ran for nearly 3 hours.
Explanation:
A semicolon is most commonly used to link (in a single sentence) two independent clauses that are closely related in thought. When a semicolon is used to join two or more ideas (parts) in a sentence, those ideas are then given equal position or rank. Use the semicolon if you have two independent clauses <em>connected without a conjunction</em>. Also use the semicolon when you already have commas within a sentence for smaller separations, and you need the semicolon to show bigger separations.
One subject, one verb -- simple sentence
2 or more simple sentences, put together with a semi-colon or comma or conjunction -- compound sentence
one independent clause, one or more dependent clauses -- complex sentence
2 or more independent clauses and 1 or more dependent ones -- compound-complex sentences
B. Walked because it is an action.
The answer is: There is no error.
Complex sentences consist of a subordinate or dependent clause, which is introduced by a subordinating conjunction like <em>even though</em>, and an independent clause, which can stand on its own. They can be separated by a comma.
In the example sentence, the subordinate clause is:
Even though I had no previous experience,
Finally, the independent clause is:
I enjoyed painting the living room with my friends.
The rest of the alternatives are incorrect because the clauses are separated or do not express the same meaning as the original sentence.
