The "4th round" typically refers to the fourth stage in a series of events, competitions, or processes. In sports, it often denotes the fourth match or game in a tournament, where teams or individuals compete to advance to the next level. For example, in football tournaments, the 4th round may determine which teams progress to the knockout stages. In other contexts, such as elections, the 4th round can refer to the fourth voting phase, where candidates are eliminated based on previous results. This process continues until a winner is determined. The term can also apply to various activities, including auctions or interviews, where multiple rounds are conducted to reach a final decision.
