Irony and Ambiguity

At first, I thought irony was the feeling of the story. But I learned that this was wrong. Actually, irony is the feeling and setting and tone of the story. There are three types of irony: Verbal, Dramatic, and Situational. I also learned about ambiguity. I used to think ambiguity was, well honestly, i didn't know anything thing about it, let alone to have a thought and idea about it. but I learned that ambiguity is unclearness by virtue of having more than one meaning. On my irony and ambiguity pretest, I was below grade-level. On my posttest, I hope that I will be at leats at grade level, if not above grade-level.
