Problem: Please answer a question about the following article about Namibia:
Whites (mainly of Afrikaner, German, British and Portuguese origin) make up between 4.0 and 7.0% of the population. Although their percentage of population is decreasing due to emigration and lower birth rates they still form the second-largest population of European ancestry, both in terms of percentage and actual numbers, in Sub-Saharan Africa (after South Africa). The majority of Namibian whites and nearly all those who are mixed race speak Afrikaans and share similar origins, culture, and religion as the white and coloured populations of South Africa. A large minority of whites (around 30,000) trace their family origins back to the German settlers who colonized Namibia prior to the British confiscation of German lands after World War One, and they maintain German cultural and educational institutions. Nearly all Portuguese settlers came to the country from the former Portuguese colony of Angola. The 1960 census reported 526,004 persons in what was then South-West Africa, including 73,464 whites (14%).
Whites make up how much of Namibia's population?
A: 4.0 and 7.0%
Problem: Please answer a question about the following article about Northwestern University:
Like other American research universities, Northwestern was transformed by World War II. Franklyn B. Snyder led the university from 1939 to 1949, when nearly 50,000 military officers and personnel were trained on the Evanston and Chicago campuses. After the war, surging enrollments under the G.I. Bill drove drastic expansion of both campuses. In 1948 prominent anthropologist Melville J. Herskovits founded the Program of African Studies at Northwestern, the first center of its kind at an American academic institution. J. Roscoe Miller's tenure as president from 1949 to 1970 was responsible for the expansion of the Evanston campus, with the construction of the lakefill on Lake Michigan, growth of the faculty and new academic programs, as well as polarizing Vietnam-era student protests. In 1978, the first and second Unabomber attacks occurred at Northwestern University. Relations between Evanston and Northwestern were strained throughout much of the post-war era because of episodes of disruptive student activism, disputes over municipal zoning, building codes, and law enforcement, as well as restrictions on the sale of alcohol near campus until 1972. Northwestern's exemption from state and municipal property tax obligations under its original charter has historically been a source of town and gown tension.
Under what Bill did enrollments surge after the war?
A: G.I. Bill
Problem: Please answer a question about the following article about Bird migration:
Migratory birds may use two electromagnetic tools to find their destinations: one that is entirely innate and another that relies on experience. A young bird on its first migration flies in the correct direction according to the Earth's magnetic field, but does not know how far the journey will be. It does this through a radical pair mechanism whereby chemical reactions in special photo pigments sensitive to long wavelengths are affected by the field. Although this only works during daylight hours, it does not use the position of the sun in any way. At this stage the bird is in the position of a boy scout with a compass but no map, until it grows accustomed to the journey and can put its other capabilities to use. With experience it learns various landmarks and this "mapping" is done by magnetites in the trigeminal system, which tell the bird how strong the field is. Because birds migrate between northern and southern regions, the magnetic field strengths at different latitudes let it interpret the radical pair mechanism more accurately and let it know when it has reached its destination. There is a neural connection between the eye and "Cluster N", the part of the forebrain that is active during migrational orientation, suggesting that birds may actually be able to see the magnetic field of the earth.
What is Cluster N?
A: the part of the forebrain that is active during migrational orientation
Problem: Please answer a question about the following article about Paper:
The pulp papermaking process is said to have been developed in China during the early 2nd century AD, possibly as early as the year 105 A.D., by the Han court eunuch Cai Lun, although the earliest archaeological fragments of paper derive from the 2nd century BC in China. The modern pulp and paper industry is global, with China leading its production and the United States right behind it.
Which court eunuch was associated with the papermaking process?
A:
Cai Lun
