Context and question: During Victoria's first pregnancy in 1840, in the first few months of the marriage, 18-year-old Edward Oxford attempted to assassinate her while she was riding in a carriage with Prince Albert on her way to visit her mother. Oxford fired twice, but either both bullets missed or, as he later claimed, the guns had no shot. He was tried for high treason and found guilty, but was acquitted on the grounds of insanity. In the immediate aftermath of the attack, Victoria's popularity soared, mitigating residual discontent over the Hastings affair and the bedchamber crisis. Her daughter, also named Victoria, was born on 21 November 1840. The Queen hated being pregnant, viewed breast-feeding with disgust, and thought newborn babies were ugly. Nevertheless, over the following seventeen years, she and Albert had a further eight children: Albert Edward, Prince of Wales (b. 1841), Alice (b. 1843), Alfred (b. 1844), Helena (b. 1846), Louise (b. 1848), Arthur (b. 1850), Leopold (b. 1853) and Beatrice (b. 1857).
When was Queen Victoria's first daughter born? 
Answer: 21 November 1840
Context and question: On 2 March 1882, Roderick Maclean, a disgruntled poet apparently offended by Victoria's refusal to accept one of his poems, shot at the Queen as her carriage left Windsor railway station. Two schoolboys from Eton College struck him with their umbrellas, until he was hustled away by a policeman. Victoria was outraged when he was found not guilty by reason of insanity, but was so pleased by the many expressions of loyalty after the attack that she said it was "worth being shot at—to see how much one is loved".
What school did the boys who defended the Queen with umbrellas attend? 
Answer: Eton College
Context and question: The service's B-2A aircraft entered service in the 1990s, its B-1B aircraft in the 1980s and its current B-52H aircraft in the early 1960s. The B-52 Stratofortress airframe design is over 60 years old and the B-52H aircraft currently in the active inventory were all built between 1960 and 1962. The B-52H is scheduled to remain in service for another 30 years, which would keep the airframe in service for nearly 90 years, an unprecedented length of service for any aircraft. The B-21 is projected to replace the B-52 and parts of the B-1B force by the mid-2020s.
When did the USAF introduce the B-1B aircraft? 
Answer:
1980s
