Step-by-step explanation:
A topic web can be used to narrow a topic, explain a topic, generate a topic, or research a topic. When choosing a topic for an essay or research paper, finding the right scope is essential. A too broad topic can lead to generalizations, while a very narrow one might not provide enough material for exploration.
To find an appropriate topic, the brainstorming technique can be employed by listing all the possible ideas and then combining related ones. This can give you an insight into which ideas are worth exploring in more depth.

Selecting a topic with substantial evidence allows for a robust discussion and makes writing the paper easier as it provides ample details to draw from.
In summary, a topic web is a versatile tool that can help you organize your thoughts, explore various aspects of a topic, and ultimately support you in crafting a well-defined angle for your essay or research paper.
