which phrase signals a solution to a problem?\nfor this reason\nit was said\nit is well known\nin either case
Answer
Answer:
A. For this reason
Brief Explanations:
"For this reason" often links a problem - identified reason to a subsequent solution. The other phrases do not signal a solution. "It was said" is just a statement of something being uttered, "It is well known" is about common knowledge, and "In either case" is about considering two situations, not signaling a solution.
