Question: Extract the answer to the question from the following context. Question: An antenna recognizes a? Context: Resonant antennas are expected to be used around a particular resonant frequency; an antenna must therefore be built or ordered to match the frequency range of the intended application. A particular antenna design will present a particular feedpoint impedance. While this may affect the choice of an antenna, an antenna's impedance can also be adapted to the desired impedance level of a system using a matching network while maintaining the other characteristics (except for a possible loss of efficiency).
Answer: frequency

[Q]: Extract the answer to the question from the following context. Question: What happened to Classical learning in the 15th century? Context: In Renaissance Europe, from about 1400 onwards, there was a revival of Classical learning accompanied by the development of Renaissance Humanism which placed greater emphasis on the role of the individual in society than had been the case during the Medieval period. Buildings were ascribed to specific architects Brunelleschi, Alberti, Michelangelo, Palladio and the cult of the individual had begun. There was still no dividing line between artist, architect and engineer, or any of the related vocations, and the appellation was often one of regional preference.

input: Please answer the following: Extract the answer to the question from the following context. Question: When did the Xbox launch in Japan? Context: While the original Xbox sold poorly in Japan, selling just 2 million units while it was on the market (between 2002 and 2005),[citation needed] the Xbox 360 sold even more poorly, selling only 1.5 million units from 2005 to 2011. Edge magazine reported in August 2011 that initially lackluster and subsequently falling sales in Japan, where Microsoft had been unable to make serious inroads into the dominance of domestic rivals Sony and Nintendo, had led to retailers scaling down and in some cases discontinuing sales of the Xbox 360 completely.

Please answer this: Extract the answer to the question from the following context. Question: How do the Chinese citizens fight back against corruption in companies doing business on their soil? Context: China: In China, the torch was first welcomed by Politburo Standing Committee member Zhou Yongkang and State Councilor Liu Yandong. It was subsequently passed onto CPC General Secretary Hu Jintao. A call to boycott French hypermart Carrefour from May 1 began spreading through mobile text messaging and online chat rooms amongst the Chinese over the weekend from April 12, accusing the company's major shareholder, the LVMH Group, of donating funds to the Dalai Lama. There were also calls to extend the boycott to include French luxury goods and cosmetic products. According to the Washington Times on April 15, however, the Chinese government was attempting to "calm the situation" through censorship: "All comments posted on popular Internet forum Sohu.com relating to a boycott of Carrefour have been deleted." Chinese protesters organized boycotts of the French-owned retail chain Carrefour in major Chinese cities including Kunming, Hefei and Wuhan, accusing the French nation of pro-secessionist conspiracy and anti-Chinese racism. Some burned French flags, some added Nazism's Swastika to the French flag, and spread short online messages calling for large protests in front of French consulates and embassy. The Carrefour boycott was met with anti-boycott demonstrators who insisted on entering one of the Carrefour stores in Kunming, only to be blocked by boycotters wielding large Chinese flags and hit by water bottles. The BBC reported that hundreds of people demonstrated in Beijing, Wuhan, Hefei, Kunming and Qingdao.

Problem: Extract the answer to the question from the following context. Question: What type of pine has more latewood? Context: If a heavy piece of pine is compared with a lightweight piece it will be seen at once that the heavier one contains a larger proportion of latewood than the other, and is therefore showing more clearly demarcated growth rings. In white pines there is not much contrast between the different parts of the ring, and as a result the wood is very uniform in texture and is easy to work. In hard pines, on the other hand, the latewood is very dense and is deep-colored, presenting a very decided contrast to the soft, straw-colored earlywood.

A: heavier

input: Please answer the following: Extract the answer to the question from the following context. Question: What ships were home to the planes that led the assault? Context: With the Japanese CAP out of position and the carriers at their most vulnerable, SBD Dauntlesses from Enterprise and Yorktown appeared at an altitude of 10,000 feet (3,000 m) and commenced their attack, quickly dealing fatal blows to three fleet carriers: Soryu, Kaga, and Akagi. Within minutes, all three were ablaze and had to be abandoned with great loss of life. Hiryu managed to survive the wave of dive bombers and launched a counter-attack against the American carriers which caused severe damage to Yorktown (which was later finished off by a Japanese submarine). However, a second attack from the U.S. carriers a few hours later found and destroyed Hiryu, the last remaining fleet carrier available to Nagumo. With his carriers lost and the Americans withdrawn out of range of his powerful battleships, Yamamoto was forced to call off the operation, leaving Midway in American hands. The battle proved to be a decisive victory for the Allies. For the second time, Japanese expansion had been checked and its formidable Combined Fleet was significantly weakened by the loss of four fleet carriers and many highly trained, virtually irreplaceable, personnel. Japan would be largely on the defensive for the rest of the war.
