Extract the answer to the question from the following context. Question: What did the pop up stores sell most? Context: Microsoft began an advertising campaign centered around Windows 8 and its Surface tablet in October 2012, starting with its first television advertisement premiering on October 14, 2012. Microsoft's advertising budget of US$1.5–1.8 billion was significantly larger than the US$200 million campaign used to promote Windows 95. As part of its campaign, Microsoft set up 34 pop-up stores inside malls (primarily focusing on Surface), provided training for retail employees in partnership with Intel, and collaborated with the electronics store chain Best Buy to design expanded spaces to showcase devices. In an effort to make retail displays of Windows 8 devices more "personal", Microsoft also developed a character known in English-speaking markets as "Allison Brown", whose fictional profile (including personal photos, contacts, and emails) is also featured on demonstration units of Windows 8 devices.
Ans: Surface

Extract the answer to the question from the following context. Question: Japan is whose biggest trading partner? Context: Menzies continued the expanded immigration program established under Chifley, and took important steps towards dismantling the White Australia Policy. In the early 1950s, external affairs minister Percy Spender helped to establish the Colombo Plan for providing economic aid to underdeveloped nations in Australia's region. Under that scheme many future Asian leaders studied in Australia. In 1958 the government replaced the Immigration Act's arbitrarily applied European language dictation test with an entry permit system, that reflected economic and skills criteria. In 1962, Menzies' Commonwealth Electoral Act provided that all Indigenous Australians should have the right to enrol and vote at federal elections (prior to this, indigenous people in Queensland, Western Australia and some in the Northern Territory had been excluded from voting unless they were ex-servicemen). In 1949 the Liberals appointed Dame Enid Lyons as the first woman to serve in an Australian Cabinet. Menzies remained a staunch supporter of links to the monarchy and British Commonwealth but formalised an alliance with the United States and concluded the Agreement on Commerce between Australia and Japan which was signed in July 1957 and launched post-war trade with Japan, beginning a growth of Australian exports of coal, iron ore and mineral resources that would steadily climb until Japan became Australia's largest trading partner.
Ans: Australia

Extract the answer to the question from the following context. Question: What was the main object in the mosaic? Context: The great Navicella mosaic (1305–1313) in the atrium of the Old St. Peter's is attributed to Giotto di Bondone. The giant mosaic, commissioned by Cardinal Jacopo Stefaneschi, was originally situated on the eastern porch of the old basilica and occupied the whole wall above the entrance arcade facing the courtyard. It depicted St. Peter walking on the waters. This extraordinary work was mainly destroyed during the construction of the new St. Peter's in the 17th century. Navicella means "little ship" referring to the large boat which dominated the scene, and whose sail, filled by the storm, loomed over the horizon. Such a natural representation of a seascape was known only from ancient works of art.
Ans: large boat

Extract the answer to the question from the following context. Question: Which of the following is not a type of metal: copper, zinc, or lethargy? Context: In 1982, the US Mint began minting pennies coated in copper but made primarily of zinc. With the new zinc pennies, there is the potential for zinc toxicosis, which can be fatal. One reported case of chronic ingestion of 425 pennies (over 1 kg of zinc) resulted in death due to gastrointestinal bacterial and fungal sepsis, whereas another patient, who ingested 12 grams of zinc, only showed lethargy and ataxia (gross lack of coordination of muscle movements). Several other cases have been reported of humans suffering zinc intoxication by the ingestion of zinc coins.
Ans: lethargy
