General RC Main Point Question

[bartleby]

Trying to understand the difference, if there is a difference, in correct answer choices between when the author has a stake in the argument and the author doesn't...

If the author is trying to argue against something or for something in the passage, then the main point is his/her argument and doesn't need to include detractors (or other parts of the paragraph)?

If the author is neutral or tacitly endorsing something, then the main point must encompass all the points in each paragraph?

Is there a significant difference in main point answers when the author has a say in the passage?

If they are arguing for/against something then it's their argument but the level of detail as to the basis of their argument, could or could not be in the answer choice.

If they aren't arguing something like this specifically then it's much more open. I don't know what you mean by"encompass all the points in each paragraph" but I doubt it.
