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

Example 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.
Example Output: What have spread diseases?

Example Input: Deletions of the proximal long arm of chromosome 15 (bands 15q11q13) are found in the majority of patients with two distinct genetic disorders, Angelman syndrome (AS) and Prader-Willi syndrome (PWS). The deleted regions in the two syndromes, defined cytogenetically and by using cloned DNA probes, are similar. However, deletions in AS occur on the maternally inherited chromosome 15, and deletions in PWS occur on the paternally derived chromosome 15. This observation has led to the suggestion that one or more genes in this region show differential expression dependent on parental origin (genetic imprinting). No genes of known function have previously been mapped to this region. We show here that the gene encoding the GABAA (gamma-aminobutyric acid) receptor beta 3 subunit maps to the AS/PWS region. Deletion of this gene (GABRB3) was found in AS and PWS patients with interstitial cytogenetic deletions. Evidence of beta 3 gene deletion was also found in an AS patient with an unbalanced 13;15 translocation but not in a PWS patient with an unbalanced 9;15 translocation. The localization of this receptor gene to the AS/PWS region suggests a possible role of the inhibitory neurotransmitter GABA in the pathogenesis of one or both of these syndromes.
Example Output: Angelman syndrome is associated with deletion of a part of Chromosome 15 but if the deletion occurs in the paternally inherited chromosome 15, what is the disease?

Example Input: Coming off their divisional road win over the Dolphins, the Jets flew to Ralph Wilson Stadium for a Week 4 AFC East duel with the throwback-clad Buffalo Bills. New York scored in the first quarter as running back LaDainian Tomlinson got a 1-yard touchdown run. The Jets added onto their lead in the second quarter with a 19-yard field goal from kicker Nick Folk, followed by quarterback Mark Sanchez completing a 41-yard touchdown pass to wide receiver Braylon Edwards. The Bills closed out the half with quarterback Ryan Fitzpatrick finding tight end David Martin on a 4-yard touchdown pass. New York pulled away in the third quarter as tight end Dustin Keller caught a 3-yard touchdown pass from wide receiver/quarterback Brad Smith, followed by his 2-yard touchdown reception thrown by Sanchez. Afterwards, Tomlinson's 26-yard touchdown run effectively secured the victory. Buffalo closed out the game in the fourth quarter as Fitzpatrick threw a touchdown pass to wide receiver Steve Johnson.
Example Output:
Which player scored multiple touchdowns?
