Input: Read this: In 1997, a year after the divorce, Diana was killed in a car crash in Paris. The Queen was on holiday with her extended family at Balmoral. Diana's two sons by CharlesPrinces William and Harrywanted to attend church and so the Queen and Prince Philip took them that morning. After that single public appearance, for five days the Queen and the Duke shielded their grandsons from the intense press interest by keeping them at Balmoral where they could grieve in private, but the royal family's seclusion and the failure to fly a flag at half-mast over Buckingham Palace caused public dismay. Pressured by the hostile reaction, the Queen agreed to return to London and do a live television broadcast on 5 September, the day before Diana's funeral. In the broadcast, she expressed admiration for Diana and her feelings "as a grandmother" for the two princes. As a result, much of the public hostility evaporated.
Question: From what building did the Queen do her television broadcast about Diana's death?

Output: unanswerable

Input: Read this: The RCC attempted to suppress regional and tribal affiliation, replacing it with a unified pan-Libyan identity. In doing so, they tried discrediting tribal leaders as agents of the old regime, and in August 1971 a Sabha military court tried many of them for counter-revolutionary activity. Long-standing administrative boundaries were re-drawn, crossing tribal boundaries, while pro-revolutionary modernizers replaced traditional leaders, but the communities they served often rejected them. Realizing the failures of the modernizers, Gaddafi created the Arab Socialist Union (ASU), a mass mobilization vanguard party of which he was president. The ASU recognized the RCC as its "Supreme Leading Authority", and was designed to further revolutionary enthusiasm throughout the country.
Question: What identities did the RCC try to dissuade?

Output: regional and tribal

Input: Read this: A "lock-in" is when a pub owner lets drinkers stay in the pub after the legal closing time, on the theory that once the doors are locked, it becomes a private party rather than a pub. Patrons may put money behind the bar before official closing time, and redeem their drinks during the lock-in so no drinks are technically sold after closing time. The origin of the British lock-in was a reaction to 1915 changes in the licensing laws in England and Wales, which curtailed opening hours to stop factory workers from turning up drunk and harming the war effort. Since 1915, the UK licensing laws had changed very little, with comparatively early closing times. The tradition of the lock-in therefore remained. Since the implementation of Licensing Act 2003, premises in England and Wales may apply to extend their opening hours beyond 11 pm, allowing round-the-clock drinking and removing much of the need for lock-ins. Since the smoking ban, some establishments operated a lock-in during which the remaining patrons could smoke without repercussions but, unlike drinking lock-ins, allowing smoking in a pub was still a prosecutable offence.
Question: A law of what year prompted the existence of the "lock-in"?

Output: 1915

Input: Read this: By 1990, the Census Bureau included more than a dozen ethnic/racial categories on the census, reflecting not only changing social ideas about ethnicity, but the wide variety of immigrants who had come to reside in the United States due to changing historical forces and new immigration laws in the 1960s. With a changing society, more citizens have begun to press for acknowledging multiracial ancestry. The Census Bureau changed its data collection by allowing people to self-identify as more than one ethnicity. Some ethnic groups are concerned about the potential political and economic effects, as federal assistance to historically underserved groups has depended on Census data. According to the Census Bureau, as of 2002, over 75% of all African Americans had multiracial ancestries.
Question: Why were there more immigrants in the US?

Output:
due to changing historical forces and new immigration laws in the 1960s
