Use a disfluent question or a proper question and find the answer to the question based on the given context or return None if an answer can't be found. A disfluent question is a question that has some interruptions in it while framing. A proper question is the correct form of the question without any disfluency.

[EX Q]: proper question: Where is Biraben from?
disfluent question: Where is Geoffrey Parker or rather Biraben sorry?
context: The plague repeatedly returned to haunt Europe and the Mediterranean throughout the 14th to 17th centuries. According to Biraben, the plague was present somewhere in Europe in every year between 1346 and 1671. The Second Pandemic was particularly widespread in the following years: 136063; 1374; 1400; 143839; 145657; 146466; 148185; 150003; 151831; 154448; 156366; 157388; 159699; 160211; 162340; 164454; and 166467. Subsequent outbreaks, though severe, marked the retreat from most of Europe (18th century) and northern Africa (19th century). According to Geoffrey Parker, France alone lost almost a million people to the plague in the epidemic of 162831.

[EX Q]: proper question: During what word was Jacksonville a key supply point for the North?
disfluent question: During what word was Jacksonville a key supply point for the south no I meant the North?
context: During the American Civil War, Jacksonville was a key supply point for hogs and cattle being shipped from Florida to aid the Confederate cause. The city was blockaded by Union forces, who gained control of the nearby Fort Clinch. Though no battles were fought in Jacksonville proper, the city changed hands several times between Union and Confederate forces. The Skirmish of the Brick Church in 1862 just outside Jacksonville proper resulted in the first Confederate victory in Florida. In February 1864 Union forces left Jacksonville and confronted a Confederate Army at the Battle of Olustee resulting in a Confederate victory. Union forces then retreated to Jacksonville and held the city for the remainder of the war. In March 1864 a Confederate cavalry confronted a Union expedition resulting in the Battle of Cedar Creek. Warfare and the long occupation left the city disrupted after the war.

[EX Q]: proper question: What describes objects not moving freely?
disfluent question: What is or what describes objects not moving freely?
context: Since then, and so far, general relativity has been acknowledged as the theory that best explains gravity. In GR, gravitation is not viewed as a force, but rather, objects moving freely in gravitational fields travel under their own inertia in straight lines through curved space-time defined as the shortest space-time path between two space-time events. From the perspective of the object, all motion occurs as if there were no gravitation whatsoever. It is only when observing the motion in a global sense that the curvature of space-time can be observed and the force is inferred from the object's curved path. Thus, the straight line path in space-time is seen as a curved line in space, and it is called the ballistic trajectory of the object. For example, a basketball thrown from the ground moves in a parabola, as it is in a uniform gravitational field. Its space-time trajectory (when the extra ct dimension is added) is almost a straight line, slightly curved (with the radius of curvature of the order of few light-years). The time derivative of the changing momentum of the object is what we label as gravitational force.
