Problem: Fears decreased when Stalin died in 1953 and Nikita Khruschev emerged as the Soviet Union's new leader. Soon, life in Soviet Armenia began to see rapid improvement. The church, which suffered greatly under Stalin, was revived when Catholicos Vazgen I assumed the duties of his office in 1955. In 1967, a memorial to the victims of the Armenian Genocide was built at the Tsitsernakaberd hill above the Hrazdan gorge in Yerevan. This occurred after mass demonstrations took place on the tragic event's fiftieth anniversary in 1965.
When did Vazgen acquire his position?
The answer is the following: 1955

Problem: Thermographic cameras detect radiation in the infrared range of the electromagnetic spectrum (roughly 90014,000 nanometers or 0.914 m) and produce images of that radiation. Since infrared radiation is emitted by all objects based on their temperatures, according to the black body radiation law, thermography makes it possible to "see" one's environment with or without visible illumination. The amount of radiation emitted by an object increases with temperature, therefore thermography allows one to see variations in temperature (hence the name).
In nanometers, what is the electromagnetic spectrum's range?
The answer is the following: 90014,000

Problem: French cooperation was deemed necessary to the campaign, and Eisenhower encountered a "preposterous situation" with the multiple rival factions in France. His primary objective was to move forces successfully into Tunisia, and intending to facilitate that objective, he gave his support to Francois Darlan as High Commissioner in North Africa, despite Darlan's previous high offices of state in Vichy France and his continued role as commander-in-chief of the French armed forces. The Allied leaders were "thunderstruck" by this from a political standpoint, though none of them had offered Eisenhower guidance with the problem in the course of planning the operation. Eisenhower was severely criticized for the move. Darlan was assassinated on December 24 by Fernand Bonnier de La Chapelle. Eisenhower did not take action to prevent the arrest and extrajudicial execution of Bonnier de La Chapelle by associates of Darlan acting without authority from either Vichy or the Allies, considering it a criminal rather than a military matter. Eisenhower later appointed General Henri Giraud as High Commissioner, who had been installed by the Allies as Darlan's commander-in-chief, and who had refused to postpone the execution.
Who killed Francois Darlan?
The answer is the following: Fernand Bonnier de La Chapelle

Problem: In July 1943, as a result of the American Federation of Musicians boycott of US recording studios, the a cappella vocal group The Song Spinners had a best-seller with "Comin' In On A Wing And A Prayer". In the 1950s several recording groups, notably The Hi-Los and the Four Freshmen, introduced complex jazz harmonies to a cappella performances. The King's Singers are credited with promoting interest in small-group a cappella performances in the 1960s. In 1983 an a cappella group known as The Flying Pickets had a Christmas 'number one' in the UK with a cover of Yazoo's (known in the US as Yaz) "Only You". A cappella music attained renewed prominence from the late 1980s onward, spurred by the success of Top 40 recordings by artists such as The Manhattan Transfer, Bobby McFerrin, Huey Lewis and the News, All-4-One, The Nylons, Backstreet Boys and Boyz II Men.[citation needed]
What a cappella group rose to popularity in 1943?
The answer is the following:
