Problem: Houston:

Though Houston is the largest city in the United States without formal zoning regulations, it has developed similarly to other Sun Belt cities because the city's land use regulations and legal covenants have played a similar role. Regulations include mandatory lot size for single-family houses and requirements that parking be available to tenants and customers. Such restrictions have had mixed results. Though some have blamed the city's low density, urban sprawl, and lack of pedestrian-friendliness on these policies, the city's land use has also been credited with having significant affordable housing, sparing Houston the worst effects of the 2008 real estate crisis. The city issued 42,697 building permits in 2008 and was ranked first in the list of healthiest housing markets for 2009.

Besides parking requirements, what land use regulations does Texas have?

Problem: By 6000 BCE predynastic Egyptians in the southwestern corner of Egypt were herding cattle and constructing large buildings. Subsistence in organized and permanent settlements in predynastic Egypt by the middle of the 6th millennium BCE centered predominantly on cereal and animal agriculture: cattle, goats, pigs and sheep. Metal objects replaced prior ones of stone. Tanning of animal skins, pottery and weaving were commonplace in this era also. There are indications of seasonal or only temporary occupation of the Al Fayyum in the 6th millennium BCE, with food activities centering on fishing, hunting and food-gathering. Stone arrowheads, knives and scrapers from the era are commonly found. Burial items included pottery, jewelry, farming and hunting equipment, and assorted foods including dried meat and fruit. Burial in desert environments appears to enhance Egyptian preservation rites, and dead were buried facing due west.
Which direction were large buildings built to face?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
All police officers in the United Kingdom, whatever their actual rank, are 'constables' in terms of their legal position. This means that a newly appointed constable has the same arrest powers as a Chief Constable or Commissioner. However, certain higher ranks have additional powers to authorize certain aspects of police operations, such as a power to authorize a search of a suspect's house (section 18 PACE in England and Wales) by an officer of the rank of Inspector, or the power to authorize a suspect's detention beyond 24 hours by a Superintendent.
What can only Superintendent-ranked UK officers do?
A: authorize a suspect's detention beyond 24 hours


Context and question: Although some indigenous peoples of the Americas were traditionally hunter-gatherers—and many, especially in Amazonia, still are—many groups practiced aquaculture and agriculture. The impact of their agricultural endowment to the world is a testament to their time and work in reshaping and cultivating the flora indigenous to the Americas. Although some societies depended heavily on agriculture, others practiced a mix of farming, hunting, and gathering. In some regions the indigenous peoples created monumental architecture, large-scale organized cities, chiefdoms, states, and empires.
What were many of the indigenous people of the Americas traditionally?
Answer: hunter-gatherers


Question: Boston has been a noted religious center from its earliest days. The Roman Catholic Archdiocese of Boston serves nearly 300 parishes and is based in the Cathedral of the Holy Cross (1875) in the South End, while the Episcopal Diocese of Massachusetts, with the Cathedral Church of St. Paul (1819) as its episcopal seat, serves just under 200 congregations. Unitarian Universalism has its headquarters on Beacon Hill. The Christian Scientists are headquartered in Back Bay at the Mother Church (1894). The oldest church in Boston is First Church in Boston, founded in 1630. King's Chapel, the city's first Anglican church, was founded in 1686 and converted to Unitarianism in 1785.

QUES: Antigonus II, a student of Zeno of Citium, spent most of his rule defending Macedon against Epirus and cementing Macedonian power in Greece, first against the Athenians in the Chremonidean War, and then against the Achaean League of Aratus of Sicyon. Under the Antigonids, Macedonia was often short on funds, the Pangaeum mines were no longer as productive as under Philip II, the wealth from Alexander's campaigns had been used up and the countryside pillaged by the Gallic invasion. A large number of the Macedonian population had also been resettled abroad by Alexander or had chosen to emigrate to the new eastern Greek cities. Up to two thirds of the population emigrated, and the Macedonian army could only count on a levy of 25,000 men, a significantly smaller force than under Philip II.

How large was the Macedonian army under the Antigonids?
What is the answer?
ANS:
25,000 men
