Article: During the Cold War between the Soviet Union and the United States, huge stockpiles of uranium were amassed and tens of thousands of nuclear weapons were created using enriched uranium and plutonium made from uranium. Since the break-up of the Soviet Union in 1991, an estimated 600 short tons (540 metric tons) of highly enriched weapons grade uranium (enough to make 40,000 nuclear warheads) have been stored in often inadequately guarded facilities in the Russian Federation and several other former Soviet states. Police in Asia, Europe, and South America on at least 16 occasions from 1993 to 2005 have intercepted shipments of smuggled bomb-grade uranium or plutonium, most of which was from ex-Soviet sources. From 1993 to 2005 the Material Protection, Control, and Accounting Program, operated by the federal government of the United States, spent approximately US $550 million to help safeguard uranium and plutonium stockpiles in Russia. This money was used for improvements and security enhancements at research and storage facilities. Scientific American reported in February 2006 that in some of the facilities security consisted of chain link fences which were in severe states of disrepair. According to an interview from the article, one facility had been storing samples of enriched (weapons grade) uranium in a broom closet before the improvement project; another had been keeping track of its stock of nuclear warheads using index cards kept in a shoe box.

Question: What was the expenditure of the Material Protection, Control, and Accounting Program between 1993 and 2005?
Ans: US $550 million

Article: Between the third and fourth sessions the pope announced reforms in the areas of Roman Curia, revision of Canon Law, regulations for mixed marriages involving several faiths, and birth control issues.

Article: In a five-to-four decision, the Supreme Court struck down the impositions of the death penalty in each of the consolidated cases as unconstitutional. The five justices in the majority did not produce a common opinion or rationale for their decision, however, and agreed only on a short statement announcing the result. The narrowest opinions, those of Byron White and Potter Stewart, expressed generalized concerns about the inconsistent application of the death penalty across a variety of cases but did not exclude the possibility of a constitutional death penalty law. Stewart and William O. Douglas worried explicitly about racial discrimination in enforcement of the death penalty. Thurgood Marshall and William J. Brennan, Jr. expressed the opinion that the death penalty was proscribed absolutely by the Eighth Amendment as "cruel and unusual" punishment.

Question: Along with Marshall, who believed that the Eighth Amendment forbade the death penalty?
Ans: William J. Brennan, Jr.

Article: Major reductions in the cost of lighting occurred with the discovery of whale oil and kerosene. Gas lighting was economical enough to power street lights in major cities starting in the early 1800s, and was also used in some commercial buildings and in the homes of wealthy people. The gas mantle boosted the luminosity of utility lighting and of kerosene lanterns. The next major drop in price came about with the incandescent light bulb powered by electricity.

Question: What type of lighting was powered by electricity?
Ans:
incandescent light
