Problem: Migration in birds is highly labile and is believed to have developed independently in many avian lineages. While it is agreed that the behavioral and physiological adaptations necessary for migration are under genetic control, some authors have argued that no genetic change is necessary for migratory behavior to develop in a sedentary species because the genetic framework for migratory behavior exists in nearly all avian lineages. This explains the rapid appearance of migratory behavior after the most recent glacial maximum.

Problem: Internet Explorer 10 is included as both a desktop program and a touch-optimized app, and includes increased support for HTML5, CSS3, and hardware acceleration. The Internet Explorer app does not support plugins or ActiveX components, but includes a version of Adobe Flash Player that is optimized for touch and low power usage. Initially, Adobe Flash would only work on sites included on a "Compatibility View" whitelist; however, after feedback from users and additional compatibility tests, an update in March 2013 changed this behavior to use a smaller blacklist of sites with known compatibility issues instead, allowing Flash to be used on most sites by default. The desktop version does not contain these limitations.
What limitations were put on Adobe flash to begin with?

Answer: a "Compatibility View" whitelist

Problem: Two rounds of Soviet purges directed by Moscow (19271934 and 19371938) resulted in the expulsion of nearly 10,000 people, from all levels of the Communist Party of Tajikistan. Ethnic Russians were sent in to replace those expelled and subsequently Russians dominated party positions at all levels, including the top position of first secretary. Between 1926 and 1959 the proportion of Russians among Tajikistan's population grew from less than 1% to 13%. Bobojon Ghafurov, Tajikistan's First Secretary of the Communist Party of Tajikistan from 19461956 was the only Tajikistani politician of significance outside of the country during the Soviet Era. He was followed in office by Tursun Uljabayev (195661), Jabbor Rasulov (19611982), and Rahmon Nabiyev (19821985, 19911992).
