Question: Uranium-235 was the first isotope that was found to be fissile. Other naturally occurring isotopes are fissionable, but not fissile. On bombardment with slow neutrons, its uranium-235 isotope will most of the time divide into two smaller nuclei, releasing nuclear binding energy and more neutrons. If too many of these neutrons are absorbed by other uranium-235 nuclei, a nuclear chain reaction occurs that results in a burst of heat or (in special circumstances) an explosion. In a nuclear reactor, such a chain reaction is slowed and controlled by a neutron poison, absorbing some of the free neutrons. Such neutron absorbent materials are often part of reactor control rods (see nuclear reactor physics for a description of this process of reactor control).
Try to answer this question if possible: What does a neutron poison absorb?
Answer: free neutrons
Question: Society in the Japanese "Tokugawa period" (Edo society), unlike the shogunates before it, was based on the strict class hierarchy originally established by Toyotomi Hideyoshi. The daimyo, or lords, were at the top, followed by the warrior-caste of samurai, with the farmers, artisans, and traders ranking below. In some parts of the country, particularly smaller regions, daimyo and samurai were more or less identical, since daimyo might be trained as samurai, and samurai might act as local lords. Otherwise, the largely inflexible nature of this social stratification system unleashed disruptive forces over time. Taxes on the peasantry were set at fixed amounts which did not account for inflation or other changes in monetary value. As a result, the tax revenues collected by the samurai landowners were worth less and less over time. This often led to numerous confrontations between noble but impoverished samurai and well-to-do peasants, ranging from simple local disturbances to much bigger rebellions. None, however, proved compelling enough to seriously challenge the established order until the arrival of foreign powers.
Try to answer this question if possible: What group were considered to be at the top of the Strict Class Hierarchy?
Answer: The daimyo, or lords
Question: On 25 February 1954, Naguib announced his resignation after the RCC held an official meeting without his presence two days prior. On 26 February, Nasser accepted the resignation, put Naguib under house arrest, and the RCC proclaimed Nasser as both RCC chairman and prime minister. As Naguib intended, a mutiny immediately followed, demanding Naguib's reinstatement and the RCC's dissolution. While visiting the striking officers at Military Headquarters (GHQ) to call for the mutiny's end, Nasser was initially intimidated into accepting their demands. However, on 27 February, Nasser's supporters in the army launched a raid on the GHQ, ending the mutiny. Later that day, hundreds of thousands of protesters, mainly belonging to the Brotherhood, called for Naguib's return and Nasser's imprisonment. In response, a sizable group within the RCC, led by Khaled Mohieddin, demanded Naguib's release and return to the presidency. Nasser was forced to acquiesce, but delayed Naguib's reinstatement until 4 March, allowing him to promote Amer to Commander of the Armed Forces—a position formerly occupied by Naguib.
Try to answer this question if possible: Who did Nasser promote to armed forces commander?
Answer: Amer
