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 makes one species provide us with a bunch of different meal options?, Context: Interspecific crop diversity is, in part, responsible for offering variety in what we eat. Intraspecific diversity, the variety of alleles within a single species, also offers us choice in our diets. If a crop fails in a monoculture, we rely on agricultural diversity to replant the land with something new. If a wheat crop is destroyed by a pest we may plant a hardier variety of wheat the next year, relying on intraspecific diversity. We may forgo wheat production in that area and plant a different species altogether, relying on interspecific diversity. Even an agricultural society which primarily grows monocultures, relies on biodiversity at some point.
Example Output: the variety of alleles

Example Input: Can BskyB refuse service to any entity?, Context: BSkyB has no veto over the presence of channels on their EPG, with open access being an enforced part of their operating licence from Ofcom. Any channel which can get carriage on a suitable beam of a satellite at 28° East is entitled to access to BSkyB's EPG for a fee, ranging from £15–100,000. Third-party channels which opt for encryption receive discounts ranging from reduced price to free EPG entries, free carriage on a BSkyB leased transponder, or actual payment for being carried. However, even in this case, BSkyB does not carry any control over the channel's content or carriage issues such as picture quality.
Example Output: BSkyB has no veto over the presence of channels

Example Input: Which happened earlier, the 1926 Imperial Conference issued the Balfour Declaration or the declaration was given legal substance under the 1931 Statute of Westminster?, Context: The ability of the Dominions to set their own foreign policy, independent of Britain, was recognised at the 1923 Imperial Conference. Britain's request for military assistance from the Dominions at the outbreak of the Chanak Crisis the previous year had been turned down by Canada and South Africa, and Canada had refused to be bound by the 1923 Treaty of Lausanne. After pressure from Ireland and South Africa, the 1926 Imperial Conference issued the Balfour Declaration, declaring the Dominions to be "autonomous Communities within the British Empire, equal in status, in no way subordinate one to another" within a "British Commonwealth of Nations". This declaration was given legal substance under the 1931 Statute of Westminster. The parliaments of Canada, Australia, New Zealand, the Union of South Africa, the Irish Free State and Newfoundland were now independent of British legislative control, they could nullify British laws and Britain could no longer pass laws for them without their consent. Newfoundland reverted to colonial status in 1933, suffering from financial difficulties during the Great Depression. Ireland distanced itself further from Britain with the introduction of a new constitution in 1937, making it a republic in all but name.
Example Output:
the 1926 Imperial Conference issued the Balfour Declaration
