A: inciting incident
Think of this incident as a spark that starts the climb that is rising action. These words all kind of sound like exactly what they are (rising action = tensions rise, etc.) so it's really not hard.

It plays a major role because it's easier to read by separating phrases.
Explanation:
For example, if you invited your grandma to eat dinner, you could say "Let's eat Grandma" but that sounds wrong. You're addressing your grandma, not eating her. So you would say "Let's eat, Grandma." with a comma to show separation. Also, commas are used like I just used it, after a transition word. And if there is more than two things that you are referring to, you use commas. For example, "pickles, cats, and dogs."
It helps a researcher to better code the data and to find/organize illustrative examples of code pieces.
