Task: Question Generation
Input (English): Background Paragraph: Because the gravitational field created by the Moon weakens with distance from the Moon, it exerts a slightly stronger than average force on the side of the Earth facing the Moon, and a slightly weaker force on the opposite side. The Moon thus tends to "stretch" the Earth slightly along the line connecting the two bodies. The solid Earth deforms a bit, but ocean water, being fluid, is free to move much more in response to the tidal force, particularly horizontally.  As the Earth rotates, the magnitude and direction of the tidal force at any particular point on the Earth's surface change constantly; although the ocean never reaches equilibrium—there is never time for the fluid to "catch up" to the state it would eventually reach if the tidal force were constant—the changing tidal force nonetheless causes rhythmic changes in sea surface height. 
Story: Mike was reading about an instrument that could measure gravity, gravimeter. He then found how gravimeter was used to measure the gravitational field of the Moon. He read about two distinct cases where the Moon's gravitational field was measured on earth, side A and side B. In side A the Moon's gravity was measured from the side where the Earth was facing the Moon. And in side B the Moon's gravitational field was measured from the opposite side of the Earth. He found these two locations showed very different consequences of Moon's gravitational field.
Output (English): Which side would see greater change in sea surface height, side A or side B?
