[Q]: Passage: Sir Ralph Moore and the Royal Niger Company had planned the attack on the Aros and the Ibini Ukpabi oracle since September 1899 but due to lack of necessary manpower, it was delayed until November 1901. On November 28, Lt. Col. Arthur Forbes Montanaro led 87 officers, 1,550 soldiers and 2,100 carriers in four axes of advance to Arochukwu from Oguta, Akwete, Unwana and Itu on a counter-insurgency campaign. As expected, Aro forces resisted all axes strongly, although they lacked modern weapons. However, Arochukwu was captured on December 28 after four days of fierce battles in and around the city. As a result, the Ibini Ukpabi shrine was allegedly blown up. Battles between British and Aro forces continued throughout the region until spring 1902 when Aro forces were defeated in the last major battle at Bende. The Aro Expedition ended three weeks later.
Question: How many years after Sir Ralph Moore and the Royal Niger Company planned an attack on the Aros and the Ibini Ukpabi oracle was it delayed?
[A]: number

[Q]: Passage: While reliable figures are difficult to obtain, estimated global sales of The Hobbit run between 35 and 100 million copies since 1937. In the UK The Hobbit has not retreated from the top 5,000 books of Nielsen BookScan since 1995, when the index began, achieving a three-year sales peak rising from 33,084 (2000) to 142,541 (2001), 126,771 (2002) and 61,229 (2003), ranking it at the 3rd position in Nielsens "Evergreen" book list. The enduring popularity of The Hobbit makes early printings of the book attractive collectors items. The first printing of the first English-language edition can sell for between 6,000 and 20,000 at auction, although the price for a signed first edition has reached over 60,000.
Question: What year were the most copies of the Hobbit sold?
[A]: date

[Q]: Passage: Henry Grey matriculated at Trinity College in 1615, and was granted an M.A. that year, during the visit of King James I of England. He married Lady Anne Cecil, daughter of William Cecil, 2nd Earl of Exeter by his second wife, Elizabeth Drury. Lady Anne Cecil was the heiress of the borough and manor of Stamford. In March 1628, Henry was created Earl of Stamford. Just before the outbreak of the English Civil War, he was included as one of the opponents of King Charles I of England, and was made lord lieutenant of Leicestershire. After some operations around Leicester, he occupied Hereford, and when compelled to abandon the city, marched to Cornwall. At the Battle of Stratton, on 16 May 1643, his troops were beaten by the Royalists; driven into Exeter, the Earl of Stamford was forced to surrender the city after a siege of three months. He was certainly no general, and was charged with cowardice. He took no further part in the military operations of the war, although once or twice he was employed on other businesses. The ravages of the Royalists had reduced him to poverty, and distrusted by the House of Commons, he had great difficulty in getting any compensation from Parliament. After a period of retirement, he declared for King Charles II of England during a rising in August 1659, and was arrested, but was soon released. Henry Grey died on 21 August 1673; his earldom passed to his grandson, Thomas Grey, 2nd Earl of Stamford.
