Câu hỏi:
There is a boat on a lake with a ladder with ten steps on it and each step is separated by a foot. Today, 3 steps of the ladder are under water before a storm passes by. After the storm, the water level raises by 5 feet, how many steps are under water now?
Đáp án:
There is still 3 steps under water because the boat floats on water.
