QUES: There is no easy way to determine when clothing was first developed, but some information has been inferred by studying lice. The body louse specifically lives in clothing, and diverge from head lice about 107,000 years ago, suggesting that clothing existed at that time. Another theory is that modern humans are the only survivors of several species of primates who may have worn clothes and that clothing may have been used as long ago as 650 thousand years ago. Other louse-based estimates put the introduction of clothing at around 42,00072,000 BP.

What organism has provided some information about the timeline of clothing?
What is the answer?
ANS: lice
QUES: By the 1990s Mexico City had become infamous as one of the world's most polluted cities; however the city has become a model for dramatically lowering pollution levels. By 2014 carbon monoxide pollution had dropped dramatically, while levels of sulfur dioxide and nitrogen dioxide were nearly three times lower than in 1992. The levels of signature pollutants in Mexico City are similar to those of Los Angeles.[citation needed] Despite the cleanup, the metropolitan area is still the most ozone-polluted part of the country, with ozone levels 2.5 times beyond WHO-defined safe limits.

Carbon Monoxide levels are about 3 times lower now than in what year?
What is the answer?
ANS: 1992
QUES: Upon its founding in 1949, West Germany had eleven states. These were reduced to nine in 1952 when three south-western states (South Baden, Wurttemberg-Hohenzollern, and Wurttemberg-Baden) merged to form Baden-Wurttemberg. From 1957, when the French-occupied Saar Protectorate was returned and formed into the Saarland, the Federal Republic consisted of ten states, which are referred to as the "Old States" today. West Berlin was under the sovereignty of the Western Allies and neither a Western German state nor part of one. However, it was in many ways de facto integrated with West Germany under a special status.

What German state did West Berlin fall under?
