Problem: Many long-distance migrants appear to be genetically programmed to respond to changing day length. Species that move short distances, however, may not need such a timing mechanism, instead moving in response to local weather conditions. Thus mountain and moorland breeders, such as wallcreeper Tichodroma muraria and white-throated dipper Cinclus cinclus, may move only altitudinally to escape the cold higher ground. Other species such as merlin Falco columbarius and Eurasian skylark Alauda arvensis move further, to the coast or towards the south. Species like the chaffinch are much less migratory in Britain than those of continental Europe, mostly not moving more than 5 km in their lives.
How far do British chaffinch more in their lives?
The answer is the following: 5 km

Problem: The organizational structure as shown above is responsible for the peacetime organization, equipping, and training of aerospace units for operational missions. When required to support operational missions, the Secretary of Defense (SECDEF) directs the Secretary of the Air Force (SECAF) to execute a Change in Operational Control (CHOP) of these units from their administrative alignment to the operational command of a Regional Combatant Commander (CCDR). In the case of AFSPC, AFSOC, PACAF, and USAFE units, forces are normally employed in-place under their existing CCDR. Likewise, AMC forces operating in support roles retain their componency to USTRANSCOM unless chopped to a Regional CCDR.
What does the abbreviation CHOP stand for?
The answer is the following: Change in Operational Control

Problem: In season ten, the total viewer numbers for the first week of shows fell 1213%, and by up to 23% in the 1849 demo compared to season nine. Later episodes, however, retained viewers better, and the season ended on a high with a significant increase in viewership for the finale up 12% for the adults 1849 demo and a 21% increase in total viewers from the season nine finale. While the overall viewer number has increased this season, its viewer demographics have continued to age year on year the median age this season was 47.2 compared to a median age of 32.1 in its first season. By the time of the 201011 television season, Fox was in its seventh consecutive season of victory overall in the 1849 demographic ratings in the United States.
What was the average age of American Idols viewers in its tenth season?
The answer is the following: 47.2

Problem: In their attempt to ensure white supremacy decades after emancipation, in the early 20th century, most southern states created laws based on the one-drop rule, defining as black, persons with any known African ancestry. This was a stricter interpretation than what had prevailed in the 19th century; it ignored the many mixed families in the state and went against commonly accepted social rules of judging a person by appearance and association. Some courts called it "the traceable amount rule." Anthropologists called it an example of a hypodescent rule, meaning that racially mixed persons were assigned the status of the socially subordinate group.
What is a hypodesecnt rule?
The answer is the following:
meaning that racially mixed persons were assigned the status of the socially subordinate group
