Problem: Please answer a question about the following article about Catalan language:
The same happens with Arabic loanwords. Thus, Catalan alfàbia "large earthenware jar" and rajola "tile", of Arabic origin, contrast with Spanish tinaja and teja, of Latin origin; whereas Catalan oli "oil" and oliva "olive", of Latin origin, contrast with Spanish aceite and aceituna. However, the Arabic element in Spanish is generally much more prevalent.
Where does the Catalan word alfabia come from?
A: of Arabic origin
Problem: Please answer a question about the following article about Houston:
Underpinning Houston's land surface are unconsolidated clays, clay shales, and poorly cemented sands up to several miles deep. The region's geology developed from river deposits formed from the erosion of the Rocky Mountains. These sediments consist of a series of sands and clays deposited on decaying organic marine matter, that over time, transformed into oil and natural gas. Beneath the layers of sediment is a water-deposited layer of halite, a rock salt. The porous layers were compressed over time and forced upward. As it pushed upward, the salt dragged surrounding sediments into salt dome formations, often trapping oil and gas that seeped from the surrounding porous sands. The thick, rich, sometimes black, surface soil is suitable for rice farming in suburban outskirts where the city continues to grow.
What geological event caused the foundations of the land beneath Houston?
A: erosion of the Rocky Mountains
Problem: Please answer a question about the following article about Plymouth:
The early port settlement of Plymouth, called "Sutton", approximates to the area now referred to as the Barbican and has 100 listed buildings and the largest concentration of cobbled streets in Britain. The Pilgrim Fathers left for the New World in 1620 near the commemorative Mayflower Steps in Sutton Pool. Also on Sutton Pool is the National Marine Aquarium which displays 400 marine species and includes Britain's deepest aquarium tank.
What was the name of the port once situated on the land occupied by present day Plymouth?
A: Sutton
Problem: Please answer a question about the following article about Electric motor:
The first commutator DC electric motor capable of turning machinery was invented by the British scientist William Sturgeon in 1832. Following Sturgeon's work, a commutator-type direct-current electric motor made with the intention of commercial use was built by the American inventor Thomas Davenport, which he patented in 1837. The motors ran at up to 600 revolutions per minute, and powered machine tools and a printing press. Due to the high cost of primary battery power, the motors were commercially unsuccessful and Davenport went bankrupt. Several inventors followed Sturgeon in the development of DC motors but all encountered the same battery power cost issues. No electricity distribution had been developed at the time. Like Sturgeon's motor, there was no practical commercial market for these motors.
Who developed the first mnotor capable of being used for machinery?
A:
William Sturgeon
