[单项选择]

The twenty-third Olympic Games, held in Los Angeles, were very much a contest of mind, muscle, and athletic determination. However, high technology, especially in the computer field, played an increasing role in both the staging of the event and the race for the gold. Computers were used to keep track of schedules, accounts, transportation, and ticketing for more than 43,000 Olympic employees and volunteers.
A sophisticated electronic message system helped to keep the 12,000 or so journalists up-to-date on results—usually within a minute after the judges’ decisions were final. Computers and other high-tech tools were also used to train American athletes by analyzing and evaluating performance, identifying weaknesses, and suggesting ways to improve.

Which of the following do computers and high-tech tools NOT do in training American athletes （　）
A. Analyze performance.
B. Suggest ways to improve.
C. Eliminate the competition
