The U.S. Government feared that Japanese Americans would be more loyal to Japan in comparison to the United States and could engage in espionage or sabotage efforts in the United States. This was not justified and is considered unconstitutional given that this was the targeting of a specific racial group for detention based upon nothing other than their ethnicity. In a report, ordered by the Carter Administration, it was found that there was little evidence of illegal activity by Japanese-American communities against the state and that these were purely racially motivated policies.
Article V (5) is the part of the Constitution in which explains how to amend the Constitution. The article states "The Congress, whenever two thirds of both houses shall deem it necessary, shall propose amendments to this Constitution, or, on the application of the legislatures of two thirds of the several states, shall call a convention for proposing amendments, which, in either case, shall be valid to all intents and purposes, as part of this Constitution, when ratified by the legislatures of three fourths of the several states, or by conventions in three fourths thereof, as the one or the other mode of ratification may be proposed by the Congress; provided that no amendment which may be made prior to the year one thousand eight hundred and eight shall in any manner affect the first and fourth clauses in the ninth section of the first article; and that no state, without its consent, shall be deprived of its equal suffrage in the Senate."
D. Breakup of Soviet Union in 1991. This caused areas of land to be unclaimed, which new countries then formed in.
Maybe while we wait for the questioner to provide the options, we can do a little general discussion here about what it means to use a primary source. Primary sources are things that come from persons directly involved in the events or lives being studied. So, any diary entries or letters of George Washington himself would count as primary sources. So would any official proclamations or letters or government documents that came from Washington's pen as president. Or the testimony of contemporaries of his who lived or worked with him would also count as primary source accounts.
So if you're looking for a historian's use of primary sources, look for the ways in which he's using historical material directly connected to the life of the person being studied. In fact, if you were able to look at a set of the false teeth George Washington wore, that would be a primary source too. They have a set at the Mount Vernon home/museum. And by looking at those actual dentures, you'd see they weren't made out of wood like the old (false) story says!
