Problem: Extract the answer to the question from the following context. Question: A metal drawn out in long and thin threads or rods used to transmit electricity or signals is called? 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.

A: wire

Problem: Extract the answer to the question from the following context. Question: The US Congress is composed of two branches, one composed of representatives and the other called? Context: Menzies ran strongly against Labor's plans to nationalise the Australian banking system and, following victory in the 1949 election, secured a double dissolution election for April 1951, after the Labor-controlled Senate refused to pass his banking legislation. The Liberal-Country Coalition was returned with control of the Senate. The Government was returned again in the 1954 election; the formation of the anti-Communist Democratic Labor Party (DLP) and the consequent split in the Australian Labor Party early in 1955 helped the Liberals to another victory in December 1955. John McEwen replaced Arthur Fadden as leader of the Country Party in March 1958 and the Menzies-McEwen Coalition was returned again at elections in November 1958 their third victory against Labor's H. V. Evatt. The Coalition was narrowly returned against Labor's Arthur Calwell in the December 1961 election, in the midst of a credit squeeze. Menzies stood for office for the last time in the November 1963 election, again defeating Calwell, with the Coalition winning back its losses in the House of Representatives. Menzies went on to resign from parliament on 26 January 1966.

A: Senate

Problem: Extract the answer to the question from the following context. Question: Humans suffer when a lighting fixture produces what? Context: Lighting fixtures come in a wide variety of styles for various functions. The most important functions are as a holder for the light source, to provide directed light and to avoid visual glare. Some are very plain and functional, while some are pieces of art in themselves. Nearly any material can be used, so long as it can tolerate the excess heat and is in keeping with safety codes.

A: visual glare

Problem: Extract the answer to the question from the following context. Question: What letter designates what Ektachrome is designed for? Context: Some high-speed black-and-white films, such as Ilford Delta 3200 and Kodak T-MAX P3200, are marketed with film speeds in excess of their true ISO speed as determined using the ISO testing method. For example, the Ilford product is actually an ISO 1000 film, according to its data sheet. The manufacturers do not indicate that the 3200 number is an ISO rating on their packaging. Kodak and Fuji also marketed E6 films designed for pushing (hence the "P" prefix), such as Ektachrome P800/1600 and Fujichrome P1600, both with a base speed of ISO 400.

A:
P
