Problem: East Prussia:

Although the 19451949 expulsion of Germans from the northern part of former East Prussia was often conducted in a violent and aggressive way by Soviet officials, the present Russian inhabitants of the Kaliningrad Oblast have much less animosity towards Germans. German names have been revived in commercial Russian trade and there is sometimes talk of reverting Kaliningrad's name to its historic name of Konigsberg. The city centre of Kaliningrad was completely rebuilt, as British bombs in 1944 and the Soviet siege in 1945 had left it in nothing but ruins.

In what year was Konigsberg renamed as Kaliningrad?

Problem: Computers control functions at many utilities, including coordination of telecommunications, the power grid, nuclear power plants, and valve opening and closing in water and gas networks. The Internet is a potential attack vector for such machines if connected, but the Stuxnet worm demonstrated that even equipment controlled by computers not connected to the Internet can be vulnerable to physical damage caused by malicious commands sent to industrial equipment (in that case uranium enrichment centrifuges) which are infected via removable media. In 2014, the Computer Emergency Readiness Team, a division of the Department of Homeland Security, investigated 79 hacking incidents at energy companies.
What department does the Computer Emergency Readiness Team belong to?
---
Answer: the Department of Homeland Security

Because sexual orientation is complex and multi-dimensional, some academics and researchers, especially in queer studies, have argued that it is a historical and social construction. In 1976, philosopher and historian Michel Foucault argued in The History of Sexuality that homosexuality as an identity did not exist in the eighteenth century; that people instead spoke of "sodomy," which referred to sexual acts. Sodomy was a crime that was often ignored, but sometimes punished severely (see sodomy law). He wrote, "'Sexuality' is an invention of the modern state, the industrial revolution, and capitalism."
What was a crime in the eighteenth century that could cause severe punishment but was mostly ignored?
A: Sodomy
