问题 What is the main idea of this passage? [br] If rats are cooled to 5℃ for 15 minutes immediately, what will happen after being allowed to return to their normal temperature?
选项 A、They have no difficult in crossing the same maze.
B、They lose their way in the maze.
C、They can remember the way correctly.
D、They go through the maze after several trying.
答案 B
解析 本题测试的是理解判断能力。文章在第三段中提到的这类老鼠的反应是：Rats in the second group which was cooled immediately after learning the maze, on the other hand，could not negotiate the maze successfully，i.e. they apparently could not remember what they had learned．由此可见本题的最佳选项是B项“它们在迷宫中迷路了”。
