Problem: Paris:

Paris in its early history had only the Seine and Bievre rivers for water. From 1809, the Canal de l'Ourcq provided Paris with water from less-polluted rivers to the north-east of the capital. From 1857, the civil engineer Eugene Belgrand, under Napoleon III, oversaw the construction of a series of new aqueducts that brought water from locations all around the city to several reservoirs built atop the Capital's highest points of elevation. From then on, the new reservoir system became Paris' principal source of drinking water, and the remains of the old system, pumped into lower levels of the same reservoirs, were from then on used for the cleaning of Paris' streets. This system is still a major part of Paris' modern water-supply network. Today Paris has more than 2,400 km (1,491 mi) of underground passageways dedicated to the evacuation of Paris' liquid wastes.

Who was Eugene Belgrand under?

A: Napoleon III

Problem: Capacitor:

The simplest model capacitor consists of two thin parallel conductive plates separated by a dielectric with permittivity . This model may also be used to make qualitative predictions for other device geometries. The plates are considered to extend uniformly over an area A and a charge density = Q/A exists on their surface. Assuming that the length and width of the plates are much greater than their separation d, the electric field near the centre of the device will be uniform with the magnitude E = /. The voltage is defined as the line integral of the electric field between the plates

In an ideal model of a capacitor, what must be assumed about the size of the plates?
---
A: much greater than their separation d

Problem: Royal assent:

Special procedures apply to legislation passed by Tynwald, the legislature of the Isle of Man. Before the lordship of the Island was purchased by the British Crown in 1765 (the Revestment), the assent of the Lord of Mann to a bill was signified by letter to the governor. After 1765, royal assent was at first signified by letter from the Secretary of State to the governor; but, during the British Regency, the practice began of granting royal assent by Order in Council, which continues to this day, though limited to exceptional cases since 1981.

What is the legislature of the Isle of Women?
---
A: unanswerable

Problem: Affirmative action in the United States:

The first appearance of the term 'affirmative action' was in the National Labor Relations Act, better known as the Wagner Act, of 1935.:15 Proposed and championed by U.S. Senator Robert F. Wagner of New York, the Wagner Act was in line with President Roosevelt's goal of providing economic security to workers and other low-income groups. During this time period it was not uncommon for employers to blacklist or fire employees associated with unions. The Wagner Act allowed workers to unionize without fear of being discriminated against, and empowered a National Labor Relations Board to review potential cases of worker discrimination. In the event of discrimination, employees were to be restored to an appropriate status in the company through 'affirmative action'. While the Wagner Act protected workers and unions it did not protect minorities, who, exempting the Congress of Industrial Organizations, were often barred from union ranks.:11 This original coining of the term therefore has little to do with affirmative action policy as it is seen today, but helped set the stage for all policy meant to compensate or address an individual's unjust treatment.[citation needed]

Who was able to review complaints about possible worker discrimination?
---
A:
National Labor Relations Board
