Problem: Please answer a question about the following article about Alloy:
The term "alloy" is sometimes used in everyday speech as a synonym for a particular alloy. For example, automobile wheels made of an aluminium alloy are commonly referred to as simply "alloy wheels", although in point of fact steels and most other metals in practical use are also alloys. Steel is such a common alloy that many items made from it, like wheels, barrels, or girders, are simply referred to by the name of the item, assuming it is made of steel. When made from other materials, they are typically specified as such, (i.e.: "bronze wheel," "plastic barrel," or "wood girder").
What is the name of a common alloy?
A: Steel
Problem: Please answer a question about the following article about Arena Football League:
The AFL currently runs as under the single-entity model, with the league owning the rights to the teams, players, and coaches. The single-entity model was adopted in 2010 when the league emerged from bankruptcy. Prior to that, the league followed the franchise model more common in North American professional sports leagues; each team essentially operated as its own business and the league itself was a separate entity which in exchange for franchise fees paid by the team owners provided rules, officials, scheduling and the other elements of organizational structure. A pool of money is allotted to teams to aid in travel costs.
Who owns the rights to the players under the single-entity model?
A: the league
Problem: Please answer a question about the following article about New Haven, Connecticut:
New Haven has a long tradition of urban planning and a purposeful design for the city's layout. The city could be argued to have some of the first preconceived layouts in the country. Upon founding, New Haven was laid out in a grid plan of nine square blocks; the central square was left open, in the tradition of many New England towns, as the city green (a commons area). The city also instituted the first public tree planting program in America. As in other cities, many of the elms that gave New Haven the nickname "Elm City" perished in the mid-20th century due to Dutch Elm disease, although many have since been replanted. The New Haven Green is currently home to three separate historic churches which speak to the original theocratic nature of the city. The Green remains the social center of the city today. It was named a National Historic Landmark in 1970.
What was the cause of the sudden extinction of many of the elms in New Haven?
A: Dutch Elm disease
Problem: Please answer a question about the following article about Sahara:
The rainfall inhibition and the dissipation of cloud cover are most accentuated over the eastern section of the Sahara rather than the western. The prevailing air mass lying above the Sahara is the continental tropical (cT) air mass which is hot and dry. Hot, dry air masses primarily form over the North-African desert from the heating of the vast continental land area, and it affects the whole desert during most of the year. Because of this extreme heating process, a thermal low is usually noticed near the surface, and is the strongest and the most developed during the summertime. The Sahara High represents the eastern continental extension of the Azores High, centered over the North Atlantic Ocean. The subsidence of the Sahara High nearly reaches the ground during the coolest part of the year while it limits to the upper troposphere during the hottest periods.
What part of the country does the air masses primarily form over?
A:
North-African desert
