Extract the answer to the question from the following context. Question: Bronze is the combination of what? Context: Iron is usually found as iron ore on Earth, except for one deposit of native iron in Greenland, which was used by the Inuit people. Native copper, however, was found worldwide, along with silver, gold and platinum, which were also used to make tools, jewelry, and other objects since Neolithic times. Copper was the hardest of these metals, and the most widely distributed. It became one of the most important metals to the ancients. Eventually, humans learned to smelt metals such as copper and tin from ore, and, around 2500 BC, began alloying the two metals to form bronze, which is much harder than its ingredients. Tin was rare, however, being found mostly in Great Britain. In the Middle East, people began alloying copper with zinc to form brass. Ancient civilizations took into account the mixture and the various properties it produced, such as hardness, toughness and melting point, under various conditions of temperature and work hardening, developing much of the information contained in modern alloy phase diagrams. Arrowheads from the Chinese Qin dynasty (around 200 BC) were often constructed with a hard bronze-head, but a softer bronze-tang, combining the alloys to prevent both dulling and breaking during use.
Ans: copper and tin

Extract the answer to the question from the following context. Question: What trait did Chopin consider the most important when playing music? Context: In 1841, Leon Escudier wrote of a recital given by Chopin that year, "One may say that Chopin is the creator of a school of piano and a school of composition. In truth, nothing equals the lightness, the sweetness with which the composer preludes on the piano; moreover nothing may be compared to his works full of originality, distinction and grace." Chopin refused to conform to a standard method of playing and believed that there was no set technique for playing well. His style was based extensively on his use of very independent finger technique. In his Projet de methode he wrote: "Everything is a matter of knowing good fingering ... we need no less to use the rest of the hand, the wrist, the forearm and the upper arm." He further stated: "One needs only to study a certain position of the hand in relation to the keys to obtain with ease the most beautiful quality of sound, to know how to play short notes and long notes, and [to attain] unlimited dexterity." The consequences of this approach to technique in Chopin's music include the frequent use of the entire range of the keyboard, passages in double octaves and other chord groupings, swiftly repeated notes, the use of grace notes, and the use of contrasting rhythms (four against three, for example) between the hands.
Ans: dexterity

Extract the answer to the question from the following context. Question: Embedded computers are found in various devices, what is a likely example that those in the manufacturing industry will not have access to? Context: Modern computers based on integrated circuits are millions to billions of times more capable than the early machines, and occupy a fraction of the space. Computers are small enough to fit into mobile devices, and mobile computers can be powered by small batteries. Personal computers in their various forms are icons of the Information Age and are generally considered as "computers". However, the embedded computers found in many devices from MP3 players to fighter aircraft and from electronic toys to industrial robots are the most numerous.
Ans: fighter aircraft

Extract the answer to the question from the following context. Question: What did Napoleon have in reserve? Context: Before the formation of the Third Coalition, Napoleon had assembled an invasion force, the Armee d'Angleterre, around six camps at Boulogne in Northern France. He intended to use this invasion force to strike at England. They never invaded, but Napoleon's troops received careful and invaluable training for future military operations. The men at Boulogne formed the core for what Napoleon later called La Grande Armee. At the start, this French army had about 200,000 men organized into seven corps, which were large field units that contained 36 to 40 cannons each and were capable of independent action until other corps could come to the rescue. A single corps properly situated in a strong defensive position could survive at least a day without support, giving the Grande Armee countless strategic and tactical options on every campaign. On top of these forces, Napoleon created a cavalry reserve of 22,000 organized into two cuirassier divisions, four mounted dragoon divisions, one division of dismounted dragoons, and one of light cavalry, all supported by 24 artillery pieces. By 1805, the Grande Armee had grown to a force of 350,000 men, who were well equipped, well trained, and led by competent officers.
Ans: 22,000 organized into two cuirassier divisions, four mounted dragoon divisions, one division of dismounted dragoons, and one of light cavalry, all supported by 24 artillery pieces
