QUES: A person can be exposed to uranium (or its radioactive daughters, such as radon) by inhaling dust in air or by ingesting contaminated water and food. The amount of uranium in air is usually very small; however, people who work in factories that process phosphate fertilizers, live near government facilities that made or tested nuclear weapons, live or work near a modern battlefield where depleted uranium weapons have been used, or live or work near a coal-fired power plant, facilities that mine or process uranium ore, or enrich uranium for reactor fuel, may have increased exposure to uranium. Houses or structures that are over uranium deposits (either natural or man-made slag deposits) may have an increased incidence of exposure to radon gas. The Occupational Safety and Health Administration (OSHA) has set the permissible exposure limit for uranium exposure in the workplace as 0.25 mg/m3 over an 8-hour workday. The National Institute for Occupational Safety and Health (NIOSH) has set a recommended exposure limit (REL) of 0.2 mg/m3 over an 8-hour workday and a short-term limit of 0.6 mg/m3. At levels of 10 mg/m3, uranium is immediately dangerous to life and health.
At what level of exposure doesn't uranium become imminently dangerous to health?

ANS: unanswerable

QUES: Buddhism provides many opportunities for comparative study with a diverse range of subjects. For example, Buddhism's emphasis on the Middle way not only provides a unique guideline for ethics but has also allowed Buddhism to peacefully coexist with various differing beliefs, customs and institutions in countries where it has resided throughout its history. Also, its moral and spiritual parallels with other systems of thoughtfor example, with various tenets of Christianityhave been subjects of close study. In addition, the Buddhist concept of dependent origination has been compared to modern scientific thought, as well as Western metaphysics.
Buddhist concept of dependent origination has been compared to what modern thought?

ANS: scientific

QUES: After 1870, the new railroads across the Plains brought hunters who killed off almost all the bison for their hides. The railroads offered attractive packages of land and transportation to European farmers, who rushed to settle the land. They (and Americans as well) also took advantage of the homestead laws to obtain free farms. Land speculators and local boosters identified many potential towns, and those reached by the railroad had a chance, while the others became ghost towns. In Kansas, for example, nearly 5000 towns were mapped out, but by 1970 only 617 were actually operating. In the mid-20th century, closeness to an interstate exchange determined whether a town would flourish or struggle for business.
In what year were the homestead laws passed?
