Problem: Please answer a question about the following article about Alps:
Roofs are traditionally constructed from Alpine rocks such as pieces of schist, gneiss or slate. Such chalets are typically found in the higher parts of the valleys, as in the Maurienne valley in Savoy, where the amount of snow during the cold months is important. The inclination of the roof cannot exceed 40%, allowing the snow to stay on top, thereby functioning as insulation from the cold. In the lower areas where the forests are widespread, wooden tiles are traditionally used. Commonly made of Norway spruce, they are called "tavaillon". The Alpine regions are multicultural and linguistically diverse. Dialects are common, and vary from valley to valley and region to region. In the Slavic Alps alone 19 dialects have been identified. Some of the French dialects spoken in the French, Swiss and Italian alps of Aosta Valley derive from Arpitan, while the southern part of the western range is related to Old Provençal; the German dialects derive from Germanic tribal languages. Romansh, spoken by two percent of the population in southeast Switzerland, is an ancient Rhaeto-Romanic language derived from Latin, remnants of ancient Celtic languages and perhaps Etruscan.
The inclination of the roof cannot exceed how much? 
A: 40%

In 1855 a reprint of a letter earlier sent to The Times appeared in Littel's Living Age. Its author, an "official Chinese interpreter of 10 years' active service" and a member of the Oriental Club, Thomas Taylor Meadows, was replying to the suggestion by another interpreter that the British Empire was wasting its resources on a false threat from Russia against China.

Problem: Sentient beings always suffer throughout saṃsāra until they free themselves from this suffering (dukkha) by attaining Nirvana. Then the absence of the first Nidāna—ignorance—leads to the absence of the others.
How do you free yourself of dukkha?
The answer is the following: attaining Nirvana


Two chains of DNA twist around each other to form a DNA double helix with the phosphate-sugar backbone spiralling around the outside, and the bases pointing inwards with adenine base pairing to thymine and guanine to cytosine. The specificity of base pairing occurs because adenine and thymine align form two hydrogen bonds, whereas cytosine and guanine form three hydrogen bonds. The two strands in a double helix must therefore be complementary, with their sequence of bases matching such that the adenines of one strand are paired with the thymines of the other strand, and so on.:4.1
What causes the specificity of base pairing?
adenine and thymine align form two hydrogen bonds, whereas cytosine and guanine form three hydrogen bonds


Input: Hunting
Hunting is the practice of killing or trapping any animal, or pursuing or tracking it with the intent of doing so. Hunting wildlife or feral animals is most commonly done by humans for food, recreation, to remove predators which are dangerous to humans or domestic animals, or for trade. In the 2010s, lawful hunting is distinguished from poaching, which is the illegal killing, trapping or capture of the hunted species. The species that are hunted are referred to as game or prey and are usually mammals and birds.

Why do humans hunt?
Output: food, recreation, to remove predators


Problem: Please answer a question about the following article about Asphalt:
Canada has the world's largest deposit of natural bitumen in the Athabasca oil sands and Canadian First Nations along the Athabasca River had long used it to waterproof their canoes. In 1719, a Cree Indian named Wa-Pa-Su brought a sample for trade to Henry Kelsey of the Hudson’s Bay Company, who was the first recorded European to see it. However, it wasn't until 1787 that fur trader and explorer Alexander MacKenzie saw the Athabasca oil sands and said, "At about 24 miles from the fork (of the Athabasca and Clearwater Rivers) are some bituminous fountains into which a pole of 20 feet long may be inserted without the least resistance."
 For what trading company did Kelsey work?
A:
Hudson’s Bay Company
