Problem: Please answer a question about the following article about Pesticide:
Since chlorinated hydrocarbon pesticides dissolve in fats and are not excreted, organisms tend to retain them almost indefinitely. Biological magnification is the process whereby these chlorinated hydrocarbons (pesticides) are more concentrated at each level of the food chain. Among marine animals, pesticide concentrations are higher in carnivorous fishes, and even more so in the fish-eating birds and mammals at the top of the ecological pyramid. Global distillation is the process whereby pesticides are transported from warmer to colder regions of the Earth, in particular the Poles and mountain tops. Pesticides that evaporate into the atmosphere at relatively high temperature can be carried considerable distances (thousands of kilometers) by the wind to an area of lower temperature, where they condense and are carried back to the ground in rain or snow.
How are levels of pesticides higher going up the food chain?
A: Biological magnification
Problem: Please answer a question about the following article about Indigenous peoples of the Americas:
Large numbers of Bolivian highland peasants retained indigenous language, culture, customs, and communal organization throughout the Spanish conquest and the post-independence period. They mobilized to resist various attempts at the dissolution of communal landholdings and used legal recognition of "empowered caciques" to further communal organization. Indigenous revolts took place frequently until 1953. While the National Revolutionary Movement government begun in 1952 discouraged self-identification as indigenous (reclassifying rural people as campesinos, or peasants), renewed ethnic and class militancy re-emerged in the Katarista movement beginning in the 1970s. Lowland indigenous peoples, mostly in the east, entered national politics through the 1990 March for Territory and Dignity organized by the CIDOB confederation. That march successfully pressured the national government to sign the ILO Convention 169 and to begin the still-ongoing process of recognizing and titling indigenous territories. The 1994 Law of Popular Participation granted "grassroots territorial organizations" that are recognized by the state certain rights to govern local areas.
What march successfully pressured the national government to sign the ILO Convetion 169?
A: March for Territory and Dignity

At about this same time, Burke was introduced to William Gerard Hamilton (known as "Single-speech Hamilton"). When Hamilton was appointed Chief Secretary for Ireland, Burke accompanied him to Dublin as his private secretary, a position he held for three years. In 1765 Burke became private secretary to the liberal Whig statesman, Charles, Marquess of Rockingham, then Prime Minister of Great Britain, who remained Burke's close friend and associate until his untimely death in 1782. Rockingham also introduced Burke as a Freemason.
Who was William Gerard Hamilton's private secretary?
A: Burke
Problem: Please answer a question about the following article about Antarctica:
During the Nimrod Expedition led by Ernest Shackleton in 1907, parties led by Edgeworth David became the first to climb Mount Erebus and to reach the South Magnetic Pole. Douglas Mawson, who assumed the leadership of the Magnetic Pole party on their perilous return, went on to lead several expeditions until retiring in 1931. In addition, Shackleton himself and three other members of his expedition made several firsts in December 1908 – February 1909: they were the first humans to traverse the Ross Ice Shelf, the first to traverse the Transantarctic Mountains (via the Beardmore Glacier), and the first to set foot on the South Polar Plateau. An expedition led by Norwegian polar explorer Roald Amundsen from the ship Fram became the first to reach the geographic South Pole on 14 December 1911, using a route from the Bay of Whales and up the Axel Heiberg Glacier. One month later, the doomed Scott Expedition reached the pole.
When did Roald Amundsen reach the geographic south pole?
A:
14 December 1911
