Problem: Race (human categorization):

Coop et al. (2009) found "a selected allele that strongly differentiates the French from both the Yoruba and Han could be strongly clinal across Europe, or at high frequency in Europe and absent elsewhere, or follow any other distribution according to the geographic nature of the selective pressure. However, we see that the global geographic distributions of these putatively selected alleles are largely determined simply by their frequencies in Yoruba, French and Han (Figure 3). The global distributions fall into three major geographic patterns that we interpret as non-African sweeps, west Eurasian sweeps and East Asian sweeps, respectively."

When did Coop and others find out something about a selected allele?

A: 2009

Problem: Strasbourg's historic city centre, the Grande Ile (Grand Island), was classified a World Heritage site by UNESCO in 1988, the first time such an honour was placed on an entire city centre. Strasbourg is immersed in the Franco-German culture and although violently disputed throughout history, has been a bridge of unity between France and Germany for centuries, especially through the University of Strasbourg, currently the second largest in France, and the coexistence of Catholic and Protestant culture. The largest Islamic place of worship in France, the Strasbourg Grand Mosque, was inaugurated by French Interior Minister Manuel Valls on 27 September 2012.
What is the culture in Strasbourg?

Context and question: The university hosts a variety of student journals, magazines, and newspapers. Established in 1872, The Yale Record is the world's oldest humor magazine. Newspapers include the Yale Daily News, which was first published in 1878, and the weekly Yale Herald, which was first published in 1986. Dwight Hall, an independent, non-profit community service organization, oversees more than 2,000 Yale undergraduates working on more than 70 community service initiatives in New Haven. The Yale College Council runs several agencies that oversee campus wide activities and student services. The Yale Dramatic Association and Bulldog Productions cater to the theater and film communities, respectively. In addition, the Yale Drama Coalition serves to coordinate between and provide resources for the various Sudler Fund sponsored theater productions which run each weekend. WYBC Yale Radio is the campus's radio station, owned and operated by students. While students used to broadcast on AM & FM frequencies, they now have an Internet-only stream.

Question: Population has outstripped the supply of freshwater, usually from rainfall. The northern atolls get 50 inches (1,300 mm) of rainfall annually; the southern atolls about twice that. The threat of drought is commonplace throughout the island chains.
Is there an answer to this question: How many millimeters of rain do the northern atolls of the Marshall Islands receive?

Answer: 1,300

Many assembled PCBs are static sensitive, and therefore must be placed in antistatic bags during transport. When handling these boards, the user must be grounded (earthed). Improper handling techniques might transmit an accumulated static charge through the board, damaging or destroying components. Even bare boards are sometimes static sensitive. Traces have become so fine that it's quite possible to blow an etch off the board (or change its characteristics) with a static charge. This is especially true on non-traditional PCBs such as MCMs and microwave PCBs.
Many assembled PABs are sensitive to what?
A:
unanswerable
