Problem: Mexico City:

The city grew as the population did, coming up against the lake's waters. As the depth of the lake water fluctuated, Mexico City was subject to periodic flooding. A major labor draft, the desagüe, compelled thousands of Indians over the colonial period to work on infrastructure to prevent flooding. Floods were not only an inconvenience but also a health hazard, since during flood periods human waste polluted the city's streets. By draining the area, the mosquito population dropped as did the frequency of the diseases they spread. However, draining the wetlands also changed the habitat for fish and birds and the areas accessible for Indian cultivation close to the capital.

How many Indians helped build the infrastructure?

A: thousands


Problem: Asphalt:

The word asphalt is derived from the late Middle English, in turn from French asphalte, based on Late Latin asphalton, asphaltum, which is the latinisation of the Greek ἄσφαλτος (ásphaltos, ásphalton), a word meaning "asphalt/bitumen/pitch", which perhaps derives from ἀ-, "without" and σφάλλω (sfallō), "make fall". Note that in French, the term asphalte is used for naturally occurring bitumen-soaked limestone deposits, and for specialised manufactured products with fewer voids or greater bitumen content than the "asphaltic concrete" used to pave roads. It is a significant fact that the first use of asphalt by the ancients was in the nature of a cement for securing or joining together various objects, and it thus seems likely that the name itself was expressive of this application. Specifically Herodotus mentioned that bitumen was brought to Babylon to build its gigantic fortification wall. From the Greek, the word passed into late Latin, and thence into French (asphalte) and English ("asphaltum" and "asphalt").

In what language is asphalte used for synthetically occurring bitumen soaked limestones?

Problem: Roman Republic:

The assembly of the tribes (i.e. the citizens of Rome), the Comitia Tributa, was presided over by a consul, and was composed of 35 tribes. The tribes were not ethnic or kinship groups, but rather geographical subdivisions. The order that the thirty-five tribes would vote in was selected randomly by lot. Once a measure received support from a majority of the tribes, the voting would end. While it did not pass many laws, the Comitia Tributa did elect quaestors, curule aediles, and military tribunes. The Plebeian Council was identical to the assembly of the tribes, but excluded the patricians (the elite who could trace their ancestry to the founding of Rome). They elected their own officers, plebeian tribunes and plebeian aediles. Usually a plebeian tribune would preside over the assembly. This assembly passed most laws, and could also act as a court of appeal.

Who would be responsible for the election of a plebeian tribune?
---
A: a plebeian


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

Unlike in Westminster style legislatures or as with the Senate Majority Leader, the House Majority Leader's duties and prominence vary depending upon the style and power of the Speaker of the House. Typically, the Speaker does not participate in debate and rarely votes on the floor. In some cases, Majority Leaders have been more influential than the Speaker; notably Tom DeLay who was more prominent than Speaker Dennis Hastert. In addition, Speaker Newt Gingrich delegated to Dick Armey an unprecedented level of authority over scheduling legislation on the House floor.

What did Tom Delay give Dick Armey the authority over on the House floor?
