Chapter 4, Mishna 6
What if father and agent betroths a woman to different men, how to discern which betrothal is valid? What is difference in status of a grown woman and a younger woman? What is status of conversions that happened in mikvah that didn’t have enough water? What if wine has been separated for terumah but then turns into vinegar? Can you use vinegar to tithe for wine? How does law of barrel compare to law of mikveh? When does a young woman become a grown woman? How do we evaluate which presumptive status prevails when two such statuses conflict?
