Problem: The origins of the Ashkenazim are obscure, and many theories have arisen speculating about their ultimate provenance. The most well supported theory is the one that details a Jewish migration through what is now Italy and other parts of southern Europe. The historical record attests to Jewish communities in southern Europe since pre-Christian times. Many Jews were denied full Roman citizenship until 212 CE, when Emperor Caracalla granted all free peoples this privilege. Jews were required to pay a poll tax until the reign of Emperor Julian in 363. In the late Roman Empire, Jews were free to form networks of cultural and religious ties and enter into various local occupations. But, after Christianity became the official religion of Rome and Constantinople in 380, Jews were increasingly marginalized.
The historical record attests to Jewish communities in southern Europe since what time?
The answer is the following: pre-Christian times

Problem: On October 28, 1989, the Ukrainian Supreme Soviet decreed that effective January 1, 1990, Ukrainian would be the official language of Ukraine, while Russian would be used for communication between ethnic groups. On the same day The Congregation of the Church of the Transfiguration in Lviv left the Russian Orthodox Church and proclaimed itself the Ukrainian Greek Catholic Church. The following day, thousands attended a memorial service at Demianiv Laz, and a temporary marker was placed to indicate that a monument to the "victims of the repressions of 1939–1941" soon would be erected.
Where was the January 2 memorial service?
The answer is the following: Demianiv Laz

Problem: Theoretical analyses show that detours that increase flight distance by up to 20% will often be adaptive on aerodynamic grounds - a bird that loads itself with food to cross a long barrier flies less efficiently. However some species show circuitous migratory routes that reflect historical range expansions and are far from optimal in ecological terms. An example is the migration of continental populations of Swainson's thrush Catharus ustulatus, which fly far east across North America before turning south via Florida to reach northern South America; this route is believed to be the consequence of a range expansion that occurred about 10,000 years ago. Detours may also be caused by differential wind conditions, predation risk, or other factors.
What kind of bird flies less efficiently?
The answer is the following: a bird that loads itself with food
