In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

Example Input: What was completed two decades and one year after Montana officially joined the United States?, Context: The state song was not composed until 21 years after statehood, when a musical troupe led by Joseph E. Howard stopped in Butte in September 1910. A former member of the troupe who lived in Butte buttonholed Howard at an after-show party, asking him to compose a song about Montana and got another partygoer, the city editor for the Butte Miner newspaper, Charles C. Cohan, to help. The two men worked up a basic melody and lyrics in about a half-hour for the entertainment of party guests, then finished the song later that evening, with an arrangement worked up the following day. Upon arriving in Helena, Howard's troupe performed 12 encores of the new song to an enthusiastic audience and the governor proclaimed it the state song on the spot, though formal legislative recognition did not occur until 1945. Montana is one of only three states to have a "state ballad", "Montana Melody", chosen by the legislature in 1983. Montana was the first state to also adopt a State Lullaby.
Example Output: The state song

Example Input: What is a part of capacitor?, Context: The maximum energy is a function of dielectric volume, permittivity, and dielectric strength. Changing the plate area and the separation between the plates while maintaining the same volume causes no change of the maximum amount of energy that the capacitor can store, so long as the distance between plates remains much smaller than both the length and width of the plates. In addition, these equations assume that the electric field is entirely concentrated in the dielectric between the plates. In reality there are fringing fields outside the dielectric, for example between the sides of the capacitor plates, which will increase the effective capacitance of the capacitor. This is sometimes called parasitic capacitance. For some simple capacitor geometries this additional capacitance term can be calculated analytically. It becomes negligibly small when the ratios of plate width to separation and length to separation are large.
Example Output: plates

Example Input: How fast is the speed of an objects fall?, Context: What we now call gravity was not identified as a universal force until the work of Isaac Newton. Before Newton, the tendency for objects to fall towards the Earth was not understood to be related to the motions of celestial objects. Galileo was instrumental in describing the characteristics of falling objects by determining that the acceleration of every object in free-fall was constant and independent of the mass of the object. Today, this acceleration due to gravity towards the surface of the Earth is usually designated as and has a magnitude of about 9.81 meters per second squared (this measurement is taken from sea level and may vary depending on location), and points toward the center of the Earth. This observation means that the force of gravity on an object at the Earth's surface is directly proportional to the object's mass. Thus an object that has a mass of will experience a force:
Example Output:
9.81 meters per second squared
