Looping.

Explanation:

Looping is a free writing technique used to narrow down the topic.

In Looping, first start by choosing a topic (even if it's unspecified yet) on which you want to write, then set a timer of 5-10 min, after this start writing on the topic non-stop for next 5-10 min. Read what you have written, then look for the idea or the topic that most interests you in the written text or circle it. Then for next 5-10 min write on the circled topic. By doing this for 4-5 times, you will discover the topic on which you want to write or that interests you the most.

The technique of LOOPING helps to reach a point where the topic of research or interest is discovered.

well basically since ima beginner people will answer any subject "right away"and if you get more points you could ask more questions or if you answer someone's question you get points

so is this a rhetorical question?
