generating more specific subtopics.

Explanation:

When you are writing a text that addresses many different subjects, or when you are dealing with a single subject that can be divided into several strands, you are likely to break the text into topics to make it more organized and easier to understand.

Often you will need, in a text, to split the main topic into several subtopics or just one subtopic. The subtopic has the same function as the topic of dividing the subject into parts, making reading easier and writing more organized.

For this reason, we can conclude that when identifying the topic, you should focus on your subject by generating more specific subtopics.
