Problem: Macintosh:

In 2000, Apple released the Power Mac G4 Cube, their first desktop since the discontinued Power Macintosh G3, to slot between the iMac G3 and the Power Mac G4. Even with its innovative design, it was initially priced US$200 higher than the comparably-equipped and more-expandable base Power Mac G4, while also not including a monitor, making it too expensive and resulting in slow sales. Apple sold just 29,000 Cubes in Q4 of 2000 which was one third of expectations, compared to 308,000 Macs during that same quarter, and Cube sales dropped to 12,000 units in Q1 of 2001. A price drop and hardware upgrades could not offset the earlier perception of the Cube's reduced value compared to the iMac and Power Mac G4 lineup, and it was discontinued in July 2001.

When was the Power Mac G4 discontinued?
---
A: July 2001

Problem: 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.

Context and question: Public opinion pressured the U.S. government to bring Villa to justice for the raid on Columbus, New Mexico; U.S. President Wilson sent Gen. John J. Pershing and some 5,000 troops into Mexico in an unsuccessful attempt to capture Villa. It was known as the Punitive Expedition. After nearly a year of pursuing Villa, American forces returned to the United States. The American intervention had been limited to the western sierras of Chihuahua. Villa had the advantage of intimately knowing the inhospitable terrain of the Sonoran Desert and the almost impassable Sierra Madre mountains and always managed to stay one step ahead of his pursuers. In 1923 Villa was assassinated by a group of seven gunmen who ambushed him while he was sitting in the back seat of his car in Parral.
In which year was Villa assassinated?
Answer: 1923

Question: In October 1919, Albert went up to Trinity College, Cambridge, where he studied history, economics and civics for a year. On 4 June 1920, he was created Duke of York, Earl of Inverness and Baron Killarney. He began to take on more royal duties. He represented his father, and toured coal mines, factories, and railyards. Through such visits he acquired the nickname of the "Industrial Prince". His stammer, and his embarrassment over it, together with his tendency to shyness, caused him to appear much less impressive than his older brother, Edward. However, he was physically active and enjoyed playing tennis. He played at Wimbledon in the Men's Doubles with Louis Greig in 1926, losing in the first round. He developed an interest in working conditions, and was President of the Industrial Welfare Society. His series of annual summer camps for boys between 1921 and 1939 brought together boys from different social backgrounds.
Is there an answer to this question: Which sport was Albert proficient at?

Answer:
tennis
