The reason why "good vs. evil" is a universal theme is because there are always two forces at work one for good and one for evil and for every good/evil thing there is an evil/good thing that will go up against each other until the end of time or at least until one of them is defeated, but then another good/evil thing will appear to take it place.
Example 1:
Your in high school and there is a bully and you try to stop the bully from hurting others. This makes you the good force and the bully the evil force (he/she doesn't have to be "evil" per-say just bad or mean will do).
"the relevance of the idea to your life"
When analyzing or writing a paper about a fictional work, you could analyze the symbolism and/or implications in the piece of fiction. In the academic setting, it simply doesn't matter if ideas conveyed in writing impact your life or not.
Michael Drayton was trying to present to the world his poems and his ideas of education. (Sorry if I’m wrong!)
The answer of what will happen after the story is the resolution (what became of it)
