Hi there, so what i know is:
as détente broke down, progress on nuclear arms control stalled completely. As their relationship continued to erode, it became clear that both the U.S. and the Soviet Union had overestimated the extent to which détente would contribute to an agreeable and peaceful end of the Cold War.

I hope this helps! And remember to always give me feedback if I got it incorrect, I promise I will make up for my mistakes :-)

World war 1 broke out in 1914 because a group of Serbian nationalists (The Black Hand) assassinated the duke of Austria-Hungary. Austria -Hungary threatened Serbia with a bunch of wishes that they wanted Serbia to due for them. Due to the treaty between Serbia and Russia, Serbia said no. Germany, who had a treaty with Austria-Hungary threatened to attack if Russia mobilized its army. Russia did and Germany invaded Belgium. This brought Great Britain and France into the war.
The answer is false. Because it says English officials when it was French representatives. Are you taking American History in Oddessyware? I'm doing the same thing and just finished First Political Party.
New evidence is discovered & Oversights and errors are corrected
Thats what i personally think because new opinions have to be backed with evidence, while if a piece of evidence is lost or stolen, it doesn't change the arguments because even though it is lost or stolen, there ought to be copies of the original object, but im not sure about new technology being applied to evidence, but it can go either or, its a 50/50 because new technology can enhance historical discoveries, or find new ones, but applying new technology as evidence has to be backed up with facts as to why it should be applied
