The editorial to which this question refers is "Yes, Virginia! There is a Santa Claus; timeless message"
Answer:
The central idea of the text is the ability to elaborate an answer to a child's question that is true, but does not compromise the child's innocence.
Explanation:
The editorial shows how a man was able to associate the existence of the Santa Claus, with the existence of feelings and inanimate things that exist in a subjective way in our life, but not in a concrete way. This answer was given to a child who wanted to know if Santa was real.
In this way they can confirm that the central idea of the text is the ability to answer children's questions in an appropriate way, without lies, but with delicacy.
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.
