Given a context passage, generate a question from the passage such that its answer is shortest continous span from the passage.

Input: Consider Input: In Week 8, the Bears donned their 1940s throwback uniforms against the Carolina Panthers, who had the worst record in the NFC. The Bears scored first on Matt Forte's 13-yard touchdown run, which would be countered by Justin Medlock's 34-yard field goal. The Panthers then took the lead on Louis Murphy's fumble recovery; Panthers quarterback Cam Newton ran with the ball, and lost the ball when Bears safety Major Wright tackled him at the 1-yard line. The ball rolled into the endzone, where Murphy recovered it. Medlock would then kick three more field goals, and by the fourth quarter, the Panthers led 19-7. The tide eventually turned when Panthers punter Brad Nortman shanked a 6-yard punt, and Jay Cutler hit Kellen Davis on a 12-yard touchdown pass with less than seven minutes left in the game. On the first play of the Panthers' next drive, Tim Jennings intercepted Newton and returned the pick 25 yards to regain the lead 20-19, after Cutler's two-point conversion passing attempt was intercepted. Medlock later kicked another field goal to reclaim the lead 22-20 with 2:27 left in the game. Cutler would lead the Bears downfield, and Gould kicked a 41-yard field goal as time expired to give Chicago the victory. The kick was Gould's tenth game-winning field goal, and the first since 2010.

Output: Who is the Panther's kicker?


Input: Consider Input: Everywhere man is altering the balance of nature.He is facilitating the spread of plants and animals into new regions, sometimes deliberately, sometimes unconsciously.He is covering huge areas with new kinds of plants, or with houses, factories, slag-heaps and other products of his civilization.He exterminates some species on a large scale, but favours the multiplication of others.In brief, he has done more in five thousand years to alter the biological aspect of the planet than has nature in five million. Many of these changes which he has brought about have had unforeseen consequences.Who would have thought that the throwing away of a piece of Canadian waterweed would have caused half the waterways of Britain to be blocked for a decade, or that the provision of pot cacti for lonely settlers' wives would have led to Eastern Australian being overrun with forests of Prickly Pear? Who would have prophesied that the cutting down of forests on the Adriatic coasts, or in parts of Central Africa, could have reduced the land to a semidesert, with the very soil washed away from the bare rock? Who would have thought that improved communications would have changed history by the spreading of disease-sleeping sickness into East Africa, measles into Oceania, very possibly malaria into ancient Greece? These are spectacular examples; but examples on a smaller scale are everywhere to be found.We make a nature sanctuary for rare birds, prescribing absolute security for all species; and we may find that some common and hardy kind of bird multiplies beyond measure and ousts the rare kinds in which we were particularly interested.We see, owing to some little change brought about by civilization, the starling spread over the English country-side in hordes.We improve the yielding capacities of our cattle; and find that now they exhaust the pastures which sufficed for less exigent stock.

Output: What have spread diseases?


Input: Consider Input: Restless legs syndrome (RLS) is a common condition that is frequently unrecognized, misdiagnosed and poorly managed. It is characterized by uncomfortable sensations deep in the legs developing at rest that compel the person to move; symptoms are worst at night and sleep disturbance is common. RLS occurs in 7%-11% of the population in Western countries, and many such people experience troublesome symptoms. Primary RLS is familial in up to two thirds of patients. RLS may also be secondary to a number of conditions including iron deficiency, pregnancy and end-stage renal failure and, perhaps, neuropathy. Secondary RLS is most common in those presenting for the first time in later life. The pathogenesis of RLS probably involves the interplay of systemic or brain iron deficiency and impaired dopaminergic neurotransmission in the subcortex of the brain. RLS is very responsive to dopaminergic therapies. Rebound of RLS symptoms during the early morning and development of severe symptoms earlier in the day (augmentation) are problematic in those treated for a prolonged period with levodopa. Consequently, dopamine agonists have become first line treatment. Anti-convulsant medications and opioids are helpful in some patients. Correction of underlying problem wherever possible is important in the management of secondary RLS.


Output: Which deficiency is the cause of restless leg syndrome?
