Input: Read this: Many bird species have established breeding populations in areas to which they have been introduced by humans. Some of these introductions have been deliberate; the ring-necked pheasant, for example, has been introduced around the world as a game bird. Others have been accidental, such as the establishment of wild monk parakeets in several North American cities after their escape from captivity. Some species, including cattle egret, yellow-headed caracara and galah, have spread naturally far beyond their original ranges as agricultural practices created suitable new habitat.
Question: The ring-necked pheasant has been introduced as what kind of bird?

Output: game bird

Input: Read this: All federal agencies are prohibited from authorizing, funding or carrying out actions that "destroy or adversely modify" critical habitats (Section 7(a) (2)). While the regulatory aspect of critical habitat does not apply directly to private and other non-federal landowners, large-scale development, logging and mining projects on private and state land typically require a federal permit and thus become subject to critical habitat regulations. Outside or in parallel with regulatory processes, critical habitats also focus and encourage voluntary actions such as land purchases, grant making, restoration, and establishment of reserves.
Question: Which aspect applies to non-federal landowners?

Output: unanswerable

Input: Read this: On 25 February 1757, Burke signed a contract with Robert Dodsley to write a "history of England from the time of Julius Caesar to the end of the reign of Queen Anne", its length being eighty quarto sheets (640 pages), nearly 400,000 words. It was to be submitted for publication by Christmas 1758. Burke completed the work to the year 1216 and stopped; it was not published until after Burke's death, being included in an 1812 collection of his works, entitled An Essay Towards an Abridgement of the English History. G. M. Young did not value Burke's history and claimed that it was "demonstrably a translation from the French". Lord Acton, on commenting on the story that Burke stopped his history because David Hume published his, said "it is ever to be regretted that the reverse did not occur".
Question: When did Burke sign a contract for a history of England?

Output: 25 February 1757
