다음 글의 내용을 한 문장으로 요약하고자 한다. 빈칸 (A)와 (B)에 들어갈 말로 가장 적절한 것은?
Umpires and other sports officials are the decision-makers and rulebook enforcers whose word is law on the field of play. Such authority comes with heavy responsibility to match. Sports officials must be unbiased masters of the rules and have thick skins. They must keep control of the conduct of games at all times, be good communicators, and stay cool in situations that can quickly grow heated ― both on the field and in the stands. For every winner in sports there is a loser, of course, and the outcome may ride on a few crucial calls. Was that three-and-two pitch a ball or a strike? Was that last-second basket a buzzer-beater or not? While instant replay provides a fallback in professional and big-time college sports, officials at other levels are on their own. The stakes can be higher than just one game. High school athletes may hope for college scholarships, and key calls against them could hurt their chances when scouts are on hand. As one veteran high school official put it, “You never know who’s in the stands.”
