Answer:
The state music contest, a competition that happens once a year, had arrived.
Explanation:
I have been able to rewrite sentences 3 and 4 as one sentence containing an appositive phrase.
An appositive phrase refers to a noun or a noun phrase that actually renames the noun next to it. The appositive phrase goes ahead to explain and give more meaning to the noun next to it.
In the above sentence, "<em>a competition that happens once a year</em>" is the appositive phrase that explains or renames "<em>The state music contest</em>".
The purpose it actually serves is to give more information about the noun.
Answer:
It took planning and perseverance to be successful.
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.
