Task: Question Answering
Input (English): Background Paragraph: When waves travel into areas of shallow water, they begin to be affected by the ocean bottom. The free orbital motion of the water is disrupted, and water particles in orbital motion no longer return to their original position. As the water becomes shallower, the swell becomes higher and steeper, ultimately assuming the familiar sharp-crested wave shape. After the wave breaks, it becomes a wave of translation and erosion of the ocean bottom intensifies. 
Story: John studies erosion of soil due to ocean wave. To facilitate his study he measured wave in three different 
points, point A, point B, and point C. Point A is in deep water. Point B is in shallow water, and point C is 
in even shallower water. He needs to publish his findings after analyzing the data. 
Question: At which point the free orbital motion of the water   would be broken, point A or point B?
Output (English): point B.
