Problem: New York City:

Ecuador, Colombia, Guyana, Peru, and Brazil were the top source countries from South America for legal immigrants to the New York City region in 2013; the Dominican Republic, Jamaica, Haiti, and Trinidad and Tobago in the Caribbean; Egypt, Ghana, and Nigeria from Africa; and El Salvador, Honduras, and Guatemala in Central America. Amidst a resurgence of Puerto Rican migration to New York City, this population had increased to approximately 1.3 million in the metropolitan area as of 2013.

Out of all nations in Central America, which provided the most legal immigrants in 2013?
---
A: El Salvador


Problem: Madrasa:

There is disagreement whether madaris ever became universities. Scholars like Arnold H. Green and Seyyed Hossein Nasr have argued that starting in the 10th century, some medieval Islamic madaris indeed became universities. George Makdisi and others, however, argue that the European university has no parallel in the medieval Islamic world. Darleen Pryds questions this view, pointing out that madaris and European universities in the Mediterranean region shared similar foundations by princely patrons and were intended to provide loyal administrators to further the rulers' agenda. Other scholars regard the university as uniquely European in origin and characteristics.

When did some madaris become considered unlike traditional colleges?

Problem: Aircraft carrier:

As "runways at sea", aircraft carriers have a flat-top flight deck, which launches and recovers aircraft. Aircraft launch forward, into the wind, and are recovered from astern. The flight deck is where the most notable differences between a carrier and a land runway are found. Creating such a surface at sea poses constraints on the carrier – for example, the fact that it is a ship means that a full-length runway would be costly to construct and maintain. This affects take-off procedure, as a shorter runway length of the deck requires that aircraft accelerate more quickly to gain lift. This either requires a thrust boost, a vertical component to its velocity, or a reduced take-off load (to lower mass). The differing types of deck configuration, as above, influence the structure of the flight deck. The form of launch assistance a carrier provides is strongly related to the types of aircraft embarked and the design of the carrier itself.

What design feature do aircraft carriers feature to hinder launching and recovering aircraft?

A: unanswerable


Problem: Great power:

Early writings on the subject tended to judge states by the realist criterion, as expressed by the historian A. J. P. Taylor when he noted that "The test of a great power is the test of strength for war." Later writers have expanded this test, attempting to define power in terms of overall military, economic, and political capacity. Kenneth Waltz, the founder of the neorealist theory of international relations, uses a set of five criteria to determine great power: population and territory; resource endowment; economic capability; political stability and competence; and military strength. These expanded criteria can be divided into three heads: power capabilities, spatial aspects, and status.

What three groups can political capacity be divided into?
