[Q]: I know that the answer to the question "What is a stripe of white fur on the underside of a dog?" is in "Domestic dogs often display the remnants of countershading, a common natural camouflage pattern. A countershaded animal will have dark coloring on its upper surfaces and light coloring below, which reduces its general visibility. Thus, many breeds will have an occasional "blaze", stripe, or "star" of white fur on their chest or underside.". Can you tell me what it is?

[A]: countershading

[Q]: I know that the answer to the question "What do the Galois groups of certain types of field extensions associated with?" is in "for any constant c. Matrix groups over these fields fall under this regime, as do adele rings and adelic algebraic groups, which are basic to number theory. Galois groups of infinite field extensions such as the absolute Galois group can also be equipped with a topology, the so-called Krull topology, which in turn is central to generalize the above sketched connection of fields and groups to infinite field extensions. An advanced generalization of this idea, adapted to the needs of algebraic geometry, is the etale fundamental group.". Can you tell me what it is?

[A]: field extensions

[Q]: I know that the answer to the question "what is the last place of business mentioned?" is in "These Christmas music marathons typically start during the week before Thanksgiving Day and end after Christmas Day, or sometimes extending to New Year's Day. Afterwards, the stations usually resume their normal music fare. Several stations begin the holiday format much earlier, at the beginning of November. The roots of this tradition can be traced back to the beautiful music and easy listening stations of the 1960s and 1970s.". Can you tell me what it is?

[A]: stations

[Q]: I know that the answer to the question "What is significant about the systeM?" is in "New claims on Antarctica have been suspended since 1959 although Norway in 2015 formally defined Queen Maud Land as including the unclaimed area between it and the South Pole. Antarctica's status is regulated by the 1959 Antarctic Treaty and other related agreements, collectively called the Antarctic Treaty System. Antarctica is defined as all land and ice shelves south of 60 S for the purposes of the Treaty System. The treaty was signed by twelve countries including the Soviet Union (and later Russia), the United Kingdom, Argentina, Chile, Australia, and the United States. It set aside Antarctica as a scientific preserve, established freedom of scientific investigation and environmental protection, and banned military activity on Antarctica. This was the first arms control agreement established during the Cold War.". Can you tell me what it is?
