question:
Question: Who did the man who won this county in the 1924 election run against in that election? Passage:Along with adjacent Newton County, Searcy is unique among Arkansas counties in being traditionally Republican in political leanings even during the overwhelmingly Democratic "Solid South" era. This Republicanism resulted from their historical paucity of slaves, in turn created by infertile soils unsuitable for intensive cotton farming, and produced support for the Union during the Civil War. These were the only two counties in Arkansas to be won by Alf Landon in 1936, Wendell Willkie in 1940, Charles Evans Hughes in 1916, and even Calvin Coolidge in 1924. In Presidential elections post-1932, Harry S. Truman and Jimmy Carter are the only Democrats to carry the county. In the 1992 election George H. W. Bush won his second-highest margin in the state, and the Republican nominee has received over 60 percent in Presidential elections from 2000 to 2012 inclusive. In 2016, Searcy County voted over 79 percent for Donald Trump, while former Arkansas First Lady Hillary Clinton received just 16 percent.

question:
Question: Which countries signed the Warsaw Pact? Passage:Through the Cold War, the United States, Soviet Union and other countries contemplated the possibility of nuclear warfare. While previous technology had developed to protect the crews of armored vehicles from projectiles and from explosive damage; the possibility of radiation arose. In the NATO countries little if any development took place on defining a doctrine of how to use armed forces without the use of tactical nuclear weapons. In the Soviet sphere of influence the legacy doctrine of operational maneuver was being theoretically examined to understand how a tank-led force could be used even with the threat of limited use of nuclear weapons on prospective European battlefields. The Warsaw Pact arrived at the solution of maneuver warfare while massively increasing the number of anti-tank weapons. To achieve this, Soviet military theorists such as Vasily Sokolovsky (1897-1968) realized that anti-tank weapons had to assume an offensive role rather than the traditionally defensive role of the Great Patriotic War (1941-1945) by becoming more mobile. This led to the development of improved guided anti-tank missiles, though similar design work was being performed in Western Europe and the United States.
