Extract the answer to the question from the following context. Question: What was Chaser's claim to fame? Context: Dog intelligence is the ability of the dog to perceive information and retain it as knowledge for applying to solve problems. Dogs have been shown to learn by inference. A study with Rico showed that he knew the labels of over 200 different items. He inferred the names of novel items by exclusion learning and correctly retrieved those novel items immediately and also 4 weeks after the initial exposure. Dogs have advanced memory skills. A study documented the learning and memory capabilities of a border collie, "Chaser", who had learned the names and could associate by verbal command over 1,000 words. Dogs are able to read and react appropriately to human body language such as gesturing and pointing, and to understand human voice commands. Dogs demonstrate a theory of mind by engaging in deception. A study showed compelling evidence that Australian dingos can outperform domestic dogs in non-social problem-solving experiment, indicating that domestic dogs may have lost much of their original problem-solving abilities once they joined humans. Another study indicated that after undergoing training to solve a simple manipulation task, dogs that are faced with an insoluble version of the same problem look at the human, while socialized wolves do not. Modern domestic dogs use humans to solve their problems for them.
Ans: learned the names and could associate by verbal command over 1,000 words

Extract the answer to the question from the following context. Question: How many times did the Allies target Hanover with bombs? Context: As an important railroad and road junction and production center, Hanover was a major target for strategic bombing during World War II, including the Oil Campaign. Targets included the AFA (Stocken), the Deurag-Nerag refinery (Misburg), the Continental plants (Vahrenwald and Limmer), the United light metal works (VLW) in Ricklingen and Laatzen (today Hanover fairground), the Hanover/Limmer rubber reclamation plant, the Hanomag factory (Linden) and the tank factory M.N.H. Maschinenfabrik Niedersachsen (Badenstedt). Forced labourers were sometimes used from the Hannover-Misburg subcamp of the Neuengamme concentration camp. Residential areas were also targeted, and more than 6,000 civilians were killed by the Allied bombing raids. More than 90% of the city center was destroyed in a total of 88 bombing raids. After the war, the Aegidienkirche was not rebuilt and its ruins were left as a war memorial.

Extract the answer to the question from the following context. Question: What country is in the NHL besides the US Context: Under the 19952004 National Hockey League collective bargaining agreement, teams were limited to nine preseason games. From 1975 to 1991, NHL teams sometimes played exhibition games against teams from the Soviet Union in the Super Series, and in 1978, played against World Hockey Association teams also in preseason training. Like the NFL, the NHL sometimes schedules exhibition games for cities without their own NHL teams, often at a club's minor league affiliate (e.g. Carolina Hurricanes games at Time Warner Cable Arena in Charlotte, home of their AHL affiliate; Los Angeles Kings games at Citizens Business Bank Arena in Ontario, California, home of their ECHL affiliate; Montreal Canadiens games at Colisee Pepsi in Quebec City, which has no pro hockey but used to have an NHL team until 1995; Washington Capitals at 1st Mariner Arena in the Baltimore Hockey Classic; various Western Canada teams at Credit Union Centre in Saskatoon, a potential NHL expansion venue). Since the 2000s, some preseason games have been played in Europe against European teams, as part of the NHL Challenge and NHL Premiere series. In addition to the standard preseason, there also exist prospect tournaments such as the Vancouver Canucks' YoungStars tournament and the Detroit Red Wings' training camp, in which NHL teams' younger prospects face off against each other under their parent club's banner.
Ans: Canada

Extract the answer to the question from the following context. Question: What was the key material used to make the highest priced dye? Context: There were guilds of dyers who specialized in red in Venice and other large Europeans cities. The Rubia plant was used to make the most common dye; it produced an orange-red or brick red color used to dye the clothes of merchants and artisans. For the wealthy, the dye used was Kermes, made from a tiny scale insect which fed on the branches and leaves of the oak tree. For those with even more money there was Polish Cochineal; also known as Kermes vermilio or "Blood of Saint John", which was made from a related insect, the Margodes polonicus. It made a more vivid red than ordinary Kermes. The finest and most expensive variety of red made from insects was the "Kermes" of Armenia (Armenian cochineal, also known as Persian kirmiz), made by collecting and crushing Porphyophora hamelii, an insect which lived on the roots and stems of certain grasses. The pigment and dye merchants of Venice imported and sold all of these products and also manufactured their own color, called Venetian red, which was considered the most expensive and finest red in Europe. Its secret ingredient was arsenic, which brightened the color.
Ans: arsenic
