In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

Ex Input:
What was the president's artistic taste?, Context: During the 19th century, an important producer of art was the Academia de San Carlos (San Carlos Art Academy), founded during colonial times, and which later became the Escuela Nacional de Artes Plasticas (the National School of Arts) including painting, sculpture and graphic design, one of UNAM's art schools. Many of the works produced by the students and faculty of that time are now displayed in the Museo Nacional de San Carlos (National Museum of San Carlos). One of the students, Jose Maria Velasco, is considered one of the greatest Mexican landscape painters of the 19th century. Porfirio Diaz's regime sponsored arts, especially those that followed the French school. Popular arts in the form of cartoons and illustrations flourished, e.g. those of Jose Guadalupe Posada and Manuel Manilla. The permanent collection of the San Carlos Museum also includes paintings by European masters such as Rembrandt, Velazquez, Murillo, and Rubens.

Ex Output:
French

Ex Input:
Who, it is assumed, was President of the United States at the time of the events which take place in the article?, Context: Whittaker was unsuited for the role and soon retired. Stewart and Harlan were conservative Republicans, while Brennan was a Democrat who became a leading voice for liberalism. In selecting a Chief Justice, Eisenhower looked for an experienced jurist who could appeal to liberals in the party as well as law-and-order conservatives, noting privately that Warren "represents the kind of political, economic, and social thinking that I believe we need on the Supreme Court ... He has a national name for integrity, uprightness, and courage that, again, I believe we need on the Court". In the next few years Warren led the Court in a series of liberal decisions that revolutionized the role of the Court.

Ex Output:
Eisenhower

Ex Input:
What size tube do Yagi-Uda arrays often use?, Context: Instead, it is often desired to have an antenna whose impedance does not vary so greatly over a certain bandwidth. It turns out that the amount of reactance seen at the terminals of a resonant antenna when the frequency is shifted, say, by 5%, depends very much on the diameter of the conductor used. A long thin wire used as a half-wave dipole (or quarter wave monopole) will have a reactance significantly greater than the resistive impedance it has at resonance, leading to a poor match and generally unacceptable performance. Making the element using a tube of a diameter perhaps 1/50 of its length, however, results in a reactance at this altered frequency which is not so great, and a much less serious mismatch which will only modestly damage the antenna's net performance. Thus rather thick tubes are typically used for the solid elements of such antennas, including Yagi-Uda arrays.
