As a teacher for nearly two decades at Metter High School, answering questions is one thing Mary Ann Stanley does best.But those questions have never been asked by celebrity-host Alex Trebek. That fact will change Monday, when 15 teachers, Stanley among them, gather at Sony Pictures Studios in Culver City, California for a two-day taping of the second ever “Jeopardy!” Teachers Tournament.The Metter High sciences teacher was chosen from thousands of online test-takers and impressed enough in subsequent interviews and assessments to be given a chance to compete for the television quiz show’s $100,000 grand prize.When taping begins Monday, Stanley hopes to be in top form as she lives out a life-long dream, which isn’t necessarily winning the contest.
