Problem: Please answer a question about the following article about 2008 Summer Olympics torch relay:
On April 20, the People's Daily published a report entitled "Overseas Chinese rally against biased media coverage, for Olympics". It included images of Chinese people demonstrating in France, the United Kingdom, Germany and the United States. One picture showed Chinese demonstrators holding a sign which claimed, incorrectly, that the BBC had not reported on Jin Jing. The People's Daily quoted one protestor who claimed the "BBC on some of the recent events has misled the British public and the rest of the world by providing intensive untruthful reports and biased coverage."
Who published "Overseas Chinese rally against biased media coverage" on April 20?
A: People's Daily
Problem: Please answer a question about the following article about Plymouth:
Upper Palaeolithic deposits, including bones of Homo sapiens, have been found in local caves, and artefacts dating from the Bronze Age to the Middle Iron Age have been found at Mount Batten showing that it was one of the main trading ports of the country at that time. An unidentified settlement named 'TAMARI OSTIA' (mouth/estuaries of the Tamar) is listed in Ptolemy's Geographia and is presumed to be located in the area of the modern city.
What is the name of the location cited by Ptolemy that is believed to have been located near modern Plymouth?
A: TAMARI OSTIA
Problem: Please answer a question about the following article about Frédéric Chopin:
Jonathan Bellman writes that modern concert performance style—set in the "conservatory" tradition of late 19th- and 20th-century music schools, and suitable for large auditoria or recordings—militates against what is known of Chopin's more intimate performance technique. The composer himself said to a pupil that "concerts are never real music, you have to give up the idea of hearing in them all the most beautiful things of art." Contemporary accounts indicate that in performance, Chopin avoided rigid procedures sometimes incorrectly attributed to him, such as "always crescendo to a high note", but that he was concerned with expressive phrasing, rhythmic consistency and sensitive colouring. Berlioz wrote in 1853 that Chopin "has created a kind of chromatic embroidery ... whose effect is so strange and piquant as to be impossible to describe ... virtually nobody but Chopin himself can play this music and give it this unusual turn". Hiller wrote that "What in the hands of others was elegant embellishment, in his hands became a colourful wreath of flowers."
Who wrote that the current large concert style conflicts with Chopin's preference of intimate performances?
A: Jonathan Bellman
Problem: Please answer a question about the following article about Electric motor:
A servomotor is a motor, very often sold as a complete module, which is used within a position-control or speed-control feedback control system mainly control valves, such as motor-operated control valves. Servomotors are used in applications such as machine tools, pen plotters, and other process systems. Motors intended for use in a servomechanism must have well-documented characteristics for speed, torque, and power. The speed vs. torque curve is quite important and is high ratio for a servo motor. Dynamic response characteristics such as winding inductance and rotor inertia are also important; these factors limit the overall performance of the servomechanism loop. Large, powerful, but slow-responding servo loops may use conventional AC or DC motors and drive systems with position or speed feedback on the motor. As dynamic response requirements increase, more specialized motor designs such as coreless motors are used. AC motors' superior power density and acceleration characteristics compared to that of DC motors tends to favor PM synchronous, BLDC, induction, and SRM drive applications.
What must be well understood when applying a servo motor for use?
A:
speed, torque, and power
