In #1, won't is stressed. In this case, does #1 mean #3?
What about in #2? When won't is not stressed strongly, does #2 mean #4?
Based on the accent, do you distinguish the meanings?
Yes, 1 and 3 have the same emphatic meaning.
2 is a fact, but without the emphasis, it's just a fact! Nothing emotional!
4 is a possibility, but not a fact.
