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

Ex Input:
Which of the following did not occur in the 20th century: urbanization, the spread of the Ottoman Empire, or wars?, Context: South Slavic historically formed a dialect continuum, i.e. each dialect has some similarities with the neighboring one, and differences grow with distance. However, migrations from the 16th to 18th centuries resulting from the spread of Ottoman Empire on the Balkans have caused large-scale population displacement that broke the dialect continuum into many geographical pockets. Migrations in the 20th century, primarily caused by urbanization and wars, also contributed to the reduction of dialectal differences.

Ex Output:
spread of Ottoman Empire


Ex Input:
What is needed to gain strength?, Context: The Armed Forces are today funded by approximately $20.1 billion annually and are presently ranked 74th in size compared to the world's other armed forces by number of total personnel, and 58th in terms of active personnel, standing at a strength of roughly 68,000, plus 27,000 reservists, 5000 Rangers, and 19,000 supplementary reserves, bringing the total force to approximately 119,000. The number of primary reserve personnel is expected to go up to 30,000 by 2020, and the number of active to at least 70,000. In addition, 5000 rangers and 19,000 supplementary personnel will be serving. If this happens the total strength would be around 124,000. These individuals serve on numerous CF bases located in all regions of the country, and are governed by the Queen's Regulations and Orders and the National Defence Act.

Ex Output:
The number of primary reserve personnel is expected to go up


Ex Input:
What contract was the first to bring in more than a billion dollars?, Context: The first Sky television rights agreement was worth £304 million over five seasons. The next contract, negotiated to start from the 1997–98 season, rose to £670 million over four seasons. The third contract was a £1.024 billion deal with BSkyB for the three seasons from 2001–02 to 2003–04. The league brought in £320 million from the sale of its international rights for the three-year period from 2004–05 to 2006–07. It sold the rights itself on a territory-by-territory basis. Sky's monopoly was broken from August 2006 when Setanta Sports was awarded rights to show two out of the six packages of matches available. This occurred following an insistence by the European Commission that exclusive rights should not be sold to one television company. Sky and Setanta paid a total of £1.7 billion, a two-thirds increase which took many commentators by surprise as it had been widely assumed that the value of the rights had levelled off following many years of rapid growth. Setanta also hold rights to a live 3 pm match solely for Irish viewers. The BBC has retained the rights to show highlights for the same three seasons (on Match of the Day) for £171.6 million, a 63 per cent increase on the £105 million it paid for the previous three-year period. Sky and BT have agreed to jointly pay £84.3 million for delayed television rights to 242 games (that is the right to broadcast them in full on television and over the internet) in most cases for a period of 50 hours after 10 pm on matchday. Overseas television rights fetched £625 million, nearly double the previous contract. The total raised from these deals is more than £2.7 billion, giving Premier League clubs an average media income from league games of around £40 million-a-year from 2007 to 2010.

Ex Output:

third contract
