Problem: With the rapid growth of industrial workers in the auto factories, labor unions such as the American Federation of Labor and the United Auto Workers fought to organize workers to gain them better working conditions and wages. They initiated strikes and other tactics in support of improvements such as the 8-hour day/40-hour work week, increased wages, greater benefits and improved working conditions. The labor activism during those years increased influence of union leaders in the city such as Jimmy Hoffa of the Teamsters and Walter Reuther of the Autoworkers.
Who was the labor leader of the Teamsters?
The answer is the following: Jimmy Hoffa

Problem: At Princeton, the physicist Robert R. Wilson encouraged Feynman to participate in the Manhattan Project—the wartime U.S. Army project at Los Alamos developing the atomic bomb. Feynman said he was persuaded to join this effort to build it before Nazi Germany developed their own bomb. He was assigned to Hans Bethe's theoretical division and impressed Bethe enough to be made a group leader. He and Bethe developed the Bethe–Feynman formula for calculating the yield of a fission bomb, which built upon previous work by Robert Serber.
What was the purpose of the Bethe-Feynman formula?
The answer is the following: calculating the yield of a fission bomb

Problem: The newer micro-USB receptacles are designed for a minimum rated lifetime of 10,000 cycles of insertion and removal between the receptacle and plug, compared to 1,500 for the standard USB and 5,000 for the mini-USB receptacle. Features intended to accomplish include, a locking device was added and the leaf-spring was moved from the jack to the plug, so that the most-stressed part is on the cable side of the connection. This change was made so that the connector on the less expensive cable would bear the most wear instead of the more expensive micro-USB device. However the idea that these changes did in fact make the connector more durable in real world use has been widely disputed, with many contending that they are in fact, much less durable.
What are the newer micro-USB receptacles designed for?
The answer is the following: a minimum rated lifetime of 10,000 cycles of insertion

Problem: On 11 July, Nasser replaced Amer with Mohamed Fawzi as general commander, over the protestations of Amer's loyalists in the military, 600 of whom marched on army headquarters and demanded Amer's reinstatement. After Nasser sacked thirty of the loyalists in response, Amer and his allies devised a plan to topple him on 27 August. Nasser was tipped off about their activities and, after several invitations, he convinced Amer to meet him at his home on 24 August. Nasser confronted Amer about the coup plot, which he denied before being arrested by Mohieddin. Amer committed suicide on 14 September. Despite his souring relationship with Amer, Nasser spoke of losing "the person closest to [him]". Thereafter, Nasser began a process of depoliticizing the armed forces, arresting dozens of leading military and intelligence figures loyal to Amer.
How did Amer react to being confronted about planning a coup?
The answer is the following:
suicide
