Problem: Question: "Which of the following is the lightest: asphalt, kerosene or bitumen?" Context: "Asphalt/bitumen is typically stored and transported at temperatures around 150 C (302 F). Sometimes diesel oil or kerosene are mixed in before shipping to retain liquidity; upon delivery, these lighter materials are separated out of the mixture. This mixture is often called "bitumen feedstock", or BFS. Some dump trucks route the hot engine exhaust through pipes in the dump body to keep the material warm. The backs of tippers carrying asphalt/bitumen, as well as some handling equipment, are also commonly sprayed with a releasing agent before filling to aid release. Diesel oil is no longer used as a release agent due to environmental concerns." Answer:

A: kerosene

input question: Question: "What happened second, the first traffic light exploded or the first modern electric traffic lights were put up?" Context: "Green can communicate safety to proceed, as in traffic lights. Green and red were standardized as the colors of international railroad signals in the 19th century. The first traffic light, using green and red gas lamps, was erected in 1868 in front of the Houses of Parliament in London. It exploded the following year, injuring the policeman who operated it. In 1912, the first modern electric traffic lights were put up in Salt Lake City, Utah. Red was chosen largely because of its high visibility, and its association with danger, while green was chosen largely because it could not be mistaken for red. Today green lights universally signal that a system is turned on and working as it should. In many video games, green signifies both health and completed objectives, opposite red." Answer:???
output answer: the first modern electric traffic lights were put up

Question: "The chromatic possibilities had what added to them?" Context: "The theories surrounding equal temperament began to be put in wider practice, especially as it enabled a wider range of chromatic possibilities in hard-to-tune keyboard instruments.

Q: Question: "Between Kerry and Hilary Clinton, which one was secretary of state second?" Context: "On December 15, 2012, several news outlets reported that President Barack Obama would nominate Kerry to succeed Hillary Clinton as Secretary of State, after Susan Rice, widely seen as Obama's preferred choice, withdrew her name from consideration citing a politicized confirmation process following criticism of her response to the 2012 Benghazi attack. On December 21, Obama proposed the nomination which received positive commentary. His confirmation hearing took place on January 24, 2013, before the Senate Foreign Relations Committee, the same panel where he first testified in 1971. The committee unanimously voted to approve him on January 29, 2013, and the same day the full Senate confirmed him on a vote of 943. In a letter to Massachusetts Governor Deval Patrick, Kerry announced his resignation from the Senate effective February 1." Answer:
A: Kerry

[Q]: Question: "__ won the Silesian Wars" Context: "Austria was not able to retake Silesia or make any significant territorial gain. However, it did prevent Prussia from invading parts of Saxony. More significantly, its military performance proved far better than during the War of the Austrian Succession and seemed to vindicate Maria Theresa's administrative and military reforms. Hence, Austria's prestige was restored in great part and the empire secured its position as a major player in the European system. Also, by promising to vote for Joseph II in the Imperial elections, Frederick II accepted the Habsburg preeminence in the Holy Roman Empire. The survival of Prussia as a first-rate power and the enhanced prestige of its king and its army, however, was potentially damaging in the long run to Austria's influence in Germany." Answer:
****
[A]:
Prussia
