Article: Thousands of Muscovites came out to defend the White House (the Russian Federation's parliament and Yeltsin's office), the symbolic seat of Russian sovereignty at the time. The organizers tried but ultimately failed to arrest Yeltsin, who rallied opposition to the coup with speech-making atop a tank. The special forces dispatched by the coup leaders took up positions near the White House, but members refused to storm the barricaded building. The coup leaders also neglected to jam foreign news broadcasts, so many Muscovites watched it unfold live on CNN. Even the isolated Gorbachev was able to stay abreast of developments by tuning into BBC World Service on a small transistor radio.

Question: What was Yeltsin doing on the tank?
Ans: speech-making


Article: In 1945, the first formal women's barbershop organization, Sweet Adelines, was formed. In 1953 Sweet Adelines became an international organization, although it didn't change its name to Sweet Adelines International until 1991. The membership of nearly 25,000 women, all singing in English, includes choruses in most of the fifty United States as well as in Australia, Canada, England, Finland, Germany, Ireland, Japan, New Zealand, Scotland, Sweden, Wales and the Netherlands. Headquartered in Tulsa, Oklahoma, the organization encompasses more than 1,200 registered quartets and 600 choruses.

Question: Where is the Sweet Adelines HQ?
Ans: Tulsa, Oklahoma


Article: Though queen, as an unmarried young woman Victoria was required by social convention to live with her mother, despite their differences over the Kensington System and her mother's continued reliance on Conroy. Her mother was consigned to a remote apartment in Buckingham Palace, and Victoria often refused to see her. When Victoria complained to Melbourne that her mother's close proximity promised "torment for many years", Melbourne sympathised but said it could be avoided by marriage, which Victoria called a "schocking  [sic] alternative". She showed interest in Albert's education for the future role he would have to play as her husband, but she resisted attempts to rush her into wedlock.

Question: Whi did Victoria have to live with because she was unmarried?
Ans: her mother


Article: While inert gas reduces filament evaporation, it also conducts heat from the filament, thereby cooling the filament and reducing efficiency. At constant pressure and temperature, the thermal conductivity of a gas depends upon the molecular weight of the gas and the cross sectional area of the gas molecules. Higher molecular weight gasses have lower thermal conductivity, because both the molecular weight is higher and also the cross sectional area is higher. Xenon gas improves efficiency because of its high molecular weight, but is also more expensive, so its use is limited to smaller lamps.

Question: What affects the thermal conductivity of a gas?
Ans:
molecular weight of the gas and the cross sectional area of the gas molecules
