Problem: Uranium:

During the later stages of World War II, the entire Cold War, and to a lesser extent afterwards, uranium-235 has been used as the fissile explosive material to produce nuclear weapons. Initially, two major types of fission bombs were built: a relatively simple device that uses uranium-235 and a more complicated mechanism that uses plutonium-239 derived from uranium-238. Later, a much more complicated and far more powerful type of fission/fusion bomb (thermonuclear weapon) was built, that uses a plutonium-based device to cause a mixture of tritium and deuterium to undergo nuclear fusion. Such bombs are jacketed in a non-fissile (unenriched) uranium case, and they derive more than half their power from the fission of this material by fast neutrons from the nuclear fusion process.

What does non-fissile mean?
---
A: unenriched

Problem: Gamal Abdel Nasser:

Nasser also attempted to maintain oversight of the country's civil service to prevent it from inflating and consequently becoming a burden to the state. New laws provided workers with a minimum wage, profit shares, free education, free health care, reduced working hours, and encouragement to participate in management. Land reforms guaranteed the security of tenant farmers, promoted agricultural growth, and reduced rural poverty. As a result of the 1962 measures, government ownership of Egyptian business reached 51 percent, and the National Union was renamed the Arab Socialist Union (ASU). With these measures came more domestic repression, as thousands of Islamists were imprisoned, including dozens of military officers. Nasser's tilt toward a Soviet-style system led his aides Boghdadi and Hussein el-Shafei to submit their resignations in protest.

What was the expression of Nasser's reforms on the street?
---
A: repression

Problem: The Blitz:

These decisions, apparently taken at the Luftflotte or Fliegerkorps level (see Organisation of the Luftwaffe (19331945)), meant attacks on individual targets were gradually replaced by what was, for all intents and purposes, an unrestricted area attack or Terrorangriff (Terror Attack). Part of the reason for this was inaccuracy of navigation. The effectiveness of British countermeasures against Knickebein, which was designed to avoid area attacks, forced the Luftwaffe to resort to these methods. The shift from precision bombing to area attack is indicated in the tactical methods and weapons dropped. KGr 100 increased its use of incendiaries from 1328 percent. By December, this had increased to 92 percent. Use of incendiaries, which were inherently inaccurate, indicated much less care was taken to avoid civilian property close to industrial sites. Other units ceased using parachute flares and opted for explosive target markers. Captured German air crews also indicated the homes of industrial workers were deliberately targeted.

What was one of the reasons for unrestricted area attacks?
---
A: inaccuracy of navigation

Problem: Dell:

In the shrinking PC industry, Dell continued to lose market share, as it dropped below Lenovo in 2011 to fall to number three in the world. Dell and fellow American contemporary Hewlett Packard came under pressure from Asian PC manufacturers Lenovo, Asus, and Acer, all of which had lower production costs and willing to accept lower profit margins. In addition, while the Asian PC vendors had been improving their quality and design, for instance Lenovo's ThinkPad series was winning corporate customers away from Dell's laptops, Dell's customer service and reputation had been slipping. Dell remained the second-most profitable PC vendor, as it took 13 percent of operating profits in the PC industry during Q4 2012, behind Apple Inc.'s Macintosh that took 45 percent, seven percent at Hewlett Packard, six percent at Lenovo and Asus, and one percent for Acer.

What industry was getting smaller?
---
A:
PC
