Problem: Please answer a question about the following article about Frederic Chopin:
From 1842 onwards, Chopin showed signs of serious illness. After a solo recital in Paris on 21 February 1842, he wrote to Grzymaa: "I have to lie in bed all day long, my mouth and tonsils are aching so much." He was forced by illness to decline a written invitation from Alkan to participate in a repeat performance of the Beethoven Seventh Symphony arrangement at Erard's on 1 March 1843. Late in 1844, Charles Halle visited Chopin and found him "hardly able to move, bent like a half-opened penknife and evidently in great pain", although his spirits returned when he started to play the piano for his visitor. Chopin's health continued to deteriorate, particularly from this time onwards. Modern research suggests that apart from any other illnesses, he may also have suffered from temporal lobe epilepsy.
What performance was Chopin forced to decline due to his increasing ill health?
A: Beethoven Seventh Symphony arrangement at Erard's
Problem: Please answer a question about the following article about Seven Years%27 War:
Great Britain lost Minorca in the Mediterranean to the French in 1756 but captured the French colonies in Senegal in 1758. The British Royal Navy took the French sugar colonies of Guadeloupe in 1759 and Martinique in 1762 as well as the Spanish cities of Havana in Cuba, and Manila in the Philippines, both prominent Spanish colonial cities. However, expansion into the hinterlands of both cities met with stiff resistance. In the Philippines, the British were confined to Manila until their agreed upon withdrawal at the war's end.
What success did the British have in Cuba?
A: Spanish cities of Havana in Cuba
Problem: Please answer a question about the following article about Printed circuit board:
During World War II, the development of the anti-aircraft proximity fuse required an electronic circuit that could withstand being fired from a gun, and could be produced in quantity. The Centralab Division of Globe Union submitted a proposal which met the requirements: a ceramic plate would be screenprinted with metallic paint for conductors and carbon material for resistors, with ceramic disc capacitors and subminiature vacuum tubes soldered in place. The technique proved viable, and the resulting patent on the process, which was classified by the U.S. Army, was assigned to Globe Union. It was not until 1984 that the Institute of Electrical and Electronics Engineers (IEEE) awarded Mr. Harry W. Rubinstein, the former head of Globe Union's Centralab Division, its coveted Cledo Brunetti Award for early key contributions to the development of printed components and conductors on a common insulating substrate. As well, Mr. Rubinstein was honored in 1984 by his alma mater, the University of Wisconsin-Madison, for his innovations in the technology of printed electronic circuits and the fabrication of capacitors.
Where did Harry Rubinstein attend college?
A: University of Wisconsin-Madison
Problem: Please answer a question about the following article about Anti-aircraft warfare:
The essence of air defence is to detect hostile aircraft and destroy them. The critical issue is to hit a target moving in three-dimensional space; an attack must not only match these three coordinates, but must do so at the time the target is at that position. This means that projectiles either have to be guided to hit the target, or aimed at the predicted position of the target at the time the projectile reaches it, taking into account speed and direction of both the target and the projectile.
What is the critical issue in air defence?
A:
to hit a target moving in three-dimensional space
