Problem: Party leaders of the United States House of Representatives:

The roles and responsibilities of the minority leader are not well-defined. To a large extent, the functions of the minority leader are defined by tradition and custom. A minority leader from 1931 to 1939, Representative Bertrand Snell, R-N.Y., provided this "job description": "He is spokesman for his party and enunciates its policies. He is required to be alert and vigilant in defense of the minority's rights. It is his function and duty to criticize constructively the policies and programs of the majority, and to this end employ parliamentary tactics and give close attention to all proposed legislation."

How defined are the roles of majority leader?

Problem: Uranium:

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.

What is the NIOSH uranium exposure standard over an 8-hour workday?
---
A: 0.2 mg/m3

Problem: Mandolin:

Another family of bowlback mandolins came from Milan and Lombardy. These mandolins are closer to the mandolino or mandore than other modern mandolins. They are shorter and wider than the standard Neapolitan mandolin, with a shallow back. The instruments have 6 strings, 3 wire treble-strings and 3 gut or wire-wrapped-silk bass-strings. The strings ran between the tuning pegs and a bridge that was glued to the soundboard, as a guitar's. The Lombardic mandolins were tuned g b e' a' d" g". A developer of the Milanese stye was Antonio Monzino (Milan) and his family who made them for 6 generations.

Who was the developer of the Milanese mandolin?

A: Antonio Monzino

Problem: Norfolk Island:

As early as 1794, Lieutenant-Governor of New South Wales Francis Grose suggested its closure as a penal settlement, as it was too remote and difficult for shipping and too costly to maintain. The first group of people left in February 1805, and by 1808 only about 200 remained, forming a small settlement until the remnants were removed in 1813. A small party remained to slaughter stock and destroy all buildings, so that there would be no inducement for anyone, especially from other European powers, to visit and lay claim to the place. From 15 February 1814 to 6 June 1825 the island was abandoned.

How many people died on Norfolk Island by 1808?
