You will be given a definition of a task first, then some input of the task.
Given a scientific passage and an answer, generate a question for the given answer.

Passage: The amplitude , , is the distance from the equilibrium (or center) point of motion to either its lowest or highest point ( end points ). The amplitude, therefore, is half of the total distance covered by the oscillating object. The amplitude can vary in harmonic motion but is constant in SHM. The amplitude of a wave often determines its strength or intensity; the exact meaning of "strength" depends on the type of wave. For example, a sound wave with a large amplitude is a loud sound and a light wave with a large amplitude is very bright. Answer: amplitude
Output:
Often determining the strength or intensity of a wave, this term is the distance from the equilibrium point of motion to either its lowest or highest point?
