Question: Who practices SODIS?, Context: Solar water disinfection (SODIS) involves exposing water-filled plastic polyethylene terephthalate (PET) bottles to sunlight for several hours. Exposure times vary depending on weather and climate from a minimum of six hours to two days during fully overcast conditions. It is recommended by the World Health Organization as a viable method for household water treatment and safe storage. Over two million people in developing countries use this method for their daily drinking water.

Question: What first lady was a member?, Context: In 1975, a group of Chicago Cubs fans based in Washington, D.C. formed the Emil Verban Society. The society is a select club of high profile Cub fans, currently headed by Illinois Senator Dick Durbin which is named for Emil Verban, who in three seasons with the Cubs in the 1940s batted .280 with 39 runs batted in and one home run. Verban was picked as the epitome of a Cub player, explains columnist George Will, because "He exemplified mediocrity under pressure, he was competent but obscure and typifying of the work ethics." Verban initially believed he was being ridiculed, but his ill feeling disappeared several years later when he was flown to Washington to meet President Ronald Reagan, also a society member, at the White House. Hillary Clinton, Jim Belushi, Joe Mantegna, Rahm Emanuel, Dick Cheney and many others have been included among its membership.

Answer: Hillary Clinton


Question: Which of the following is not an organic compound of zinc: Zn(O2CCH3)2 or Zn(CN)2?, Context: In weak basic solutions containing Zn2+ ions, the hydroxide Zn(OH)2 forms as a white precipitate. In stronger alkaline solutions, this hydroxide is dissolved to form zincates ([Zn(OH)4]2−). The nitrate Zn(NO3)2, chlorate Zn(ClO3)2, sulfate ZnSO4, phosphate Zn3(PO4)2, molybdate ZnMoO4, cyanide Zn(CN)2, arsenite Zn(AsO2)2, arsenate Zn(AsO4)2·8H2O and the chromate ZnCrO4 (one of the few colored zinc compounds) are a few examples of other common inorganic compounds of zinc. One of the simplest examples of an organic compound of zinc is the acetate (Zn(O2CCH3)2).

Answer:
Zn(CN)2
