input question: I know that the answer to the question "Whose campus included the Queen's Tower after its expansion in the 1950's and 60's?" is in "Imperial's main campus is located in the South Kensington area of central London. It is situated in an area of South Kensington, known as Albertopolis, which has a high concentration of cultural and academic institutions, adjacent to the Natural History Museum, the Science Museum, the Victoria and Albert Museum, the Royal College of Music, the Royal College of Art, the Royal Geographical Society and the Royal Albert Hall. Nearby public attractions include the Kensington Palace, Hyde Park and the Kensington Gardens, the National Art Library, and the Brompton Oratory. The expansion of the South Kensington campus in the 1950s & 1960s absorbed the site of the former Imperial Institute, designed by Thomas Collcutt, of which only the 287 foot (87 m) high Queen's Tower remains among the more modern buildings.". Can you tell me what it is????
output answer: Imperial's

I know that the answer to the question "Alloys are made of?" is in "Conversely, most heat-treatable alloys are precipitation hardening alloys, which produce the opposite effects that steel does. When heated to form a solution and then cooled quickly, these alloys become much softer than normal, during the diffusionless transformation, and then harden as they age. The solutes in these alloys will precipitate over time, forming intermetallic phases, which are difficult to discern from the base metal. Unlike steel, in which the solid solution separates to form different crystal phases, precipitation hardening alloys separate to form different phases within the same crystal. These intermetallic alloys appear homogeneous in crystal structure, but tend to behave heterogeneous, becoming hard and somewhat brittle.". Can you tell me what it is?

Answer: metal

Q: I know that the answer to the question "How many pesticides does 5.3x109lb equal?" is in "In 2006 and 2007, the world used approximately 2.4 megatonnes (5.3109 lb) of pesticides, with herbicides constituting the biggest part of the world pesticide use at 40%, followed by insecticides (17%) and fungicides (10%). In 2006 and 2007 the U.S. used approximately 0.5 megatonnes (1.1109 lb) of pesticides, accounting for 22% of the world total, including 857 million pounds (389 kt) of conventional pesticides, which are used in the agricultural sector (80% of conventional pesticide use) as well as the industrial, commercial, governmental and home & garden sectors.Pesticides are also found in majority of U.S. households with 78 million out of the 105.5 million households indicating that they use some form of pesticide. As of 2007, there were more than 1,055 active ingredients registered as pesticides, which yield over 20,000 pesticide products that are marketed in the United States.". Can you tell me what it is?
A: 2.4 megatonnes

Question: I know that the answer to the question "What caused the rise of plate armor?" is in "In the 1500s a new type of armor started to become popular due to the advent of firearms, new fighting tactics and the need for additional protection. The kozane dou made from individual scales was replaced by plate armor. This new armor, which used iron plated dou (do), was referred to as Tosei-gusoku, or modern armor. Various other components of armor protected the samurai's body. The helmet kabuto was an important part of the samurai's armor. Samurai armor changed and developed as the methods of samurai warfare changed over the centuries. The known last use of samurai armor occurring in 1877 during the satsuma rebellion. As the last samurai rebellion was crushed, Japan modernized its defenses and turned to a national conscription army that used uniforms.". Can you tell me what it is?
Answer: the advent of firearms, new fighting tactics and the need for additional protection

[Q]: I know that the answer to the question "Which contains higher frequencies, a snare drum or a bass drum?" is in "It is still possible for two sounds of indefinite pitch to clearly be higher or lower than one another. For instance, a snare drum sounds higher pitched than a bass drum though both have indefinite pitch, because its sound contains higher frequencies. In other words, it is possible and often easy to roughly discern the relative pitches of two sounds of indefinite pitch, but sounds of indefinite pitch do not neatly correspond to any specific pitch. A special type of pitch often occurs in free nature when sound reaches the ear of an observer directly from the source, and also after reflecting off a sound-reflecting surface. This phenomenon is called repetition pitch, because the addition of a true repetition of the original sound to itself is the basic prerequisite.". Can you tell me what it is?
****
[A]: a snare drum

Problem: Given the question: I know that the answer to the question "Why would increasing the number of smaller school work against the goal of the Gates Foundation policy?" is in "The K-12 and higher education reform programs of the Gates Foundation have been criticized by some education professionals, parents, and researchers because they have driven the conversation on education reform to such an extent that they may marginalize researchers who do not support Gates' predetermined policy preferences. Several Gates-backed policies such as small schools, charter schools, and increasing class sizes have been expensive and disruptive, but some studies indicate they have not improved educational outcomes and may have caused harm. Peer reviewed scientific studies at Stanford find that Charter Schools do not systematically improve student performance". Can you tell me what it is?
