Answer:
The correct answer is NO MAIN IDEA.
Step-by-step explanation:
A well-written paragraph without a stated topic sentence has NO MAIN IDEA. Hence, it is not so well-written after all, since a paragraph must have a structure within which we identify the following:
- The topic sentence, which should be stated at the beginning of the paragraph, since it is the leading idea to be discussed.
- Then, it comes the paragraph properly said.
- Finally, it is advisable that the paragraph has a round up.
