English: This is the official list of questions (and expected answers) that can be asked on the civics portion of the American naturalization test, revised in January of 2019. While most of these questions are supplied with answers, the ones that ask about specific members of the American government are not.
Operation Project 58/58A [1] was a series of 4 nuclear tests conducted by the United States in 1957–1958 at the Nevada Test Site. These tests followed the Operation Plumbbob series and preceded the Operation Hardtack I series. All the tests in Project 58 were one-point safety tests. [2]
Able Archer 83 was a military exercise conducted by NATO that took place in November 1983, as part of an annual exercise.It simulated a period of heightened nuclear tensions between NATO and the Warsaw Pact, leading to concerns that it could have been mistaken for a real attack by the Soviet Union.
The operation consisted of 29 explosions, of which only two did not produce any nuclear yield.Twenty-one laboratories and government agencies were involved. While most Operation Plumbbob tests contributed to the development of warheads for intercontinental and intermediate range missiles, they also tested air defense and anti-submarine warheads with smaller yields.
Operation Roller Coaster [1] was a series of four nuclear tests conducted jointly by the United States and the United Kingdom in 1963, at the Nevada Test Site. [2] The tests did not involve the detonation of any nuclear weapons.
Project 57 was an open-air nuclear test conducted by the United States at the Nellis Air Force Range in 1957, [1] [2] following Operation Redwing, and preceding Operation Plumbbob. The test area, also known as Area 13 , was a 10 miles (16 km) by 16 miles (26 km) block of land abutting the northeast boundary of the Nevada National Security Site .
The United States's Crosstie nuclear test series was a group of 48 nuclear tests conducted in 1967–1968. These tests [ note 1 ] followed the Operation Latchkey series and preceded the Operation Bowline series.
If there is any nuclear yield in the firing, then the test is deemed a failure from a safety standpoint. A successful test will measure only the chemical explosive in the test bomb exploding, which still, of course, blasts the bomb core and causes the core material to be spread over a wide area if the test is in open air, as all the Project 56 ...
