Problem: Please answer a question about the following article about On the Origin of Species:
Chapter I covers animal husbandry and plant breeding, going back to ancient Egypt. Darwin discusses contemporary opinions on the origins of different breeds under cultivation to argue that many have been produced from common ancestors by selective breeding. As an illustration of artificial selection, he describes fancy pigeon breeding, noting that "[t]he diversity of the breeds is something astonishing", yet all were descended from one species of rock pigeon. Darwin saw two distinct kinds of variation: (1) rare abrupt changes he called "sports" or "monstrosities" (example: ancon sheep with short legs), and (2) ubiquitous small differences (example: slightly shorter or longer bill of pigeons). Both types of hereditary changes can be used by breeders. However, for Darwin the small changes were most important in evolution.
Which evolutionary changes were the most important to Darwin?
A: the small changes

These symmetries are represented by functions. Each of these functions sends a point in the square to the corresponding point under the symmetry. For example, r1 sends a point to its rotation 90° clockwise around the square's center, and fh sends a point to its reflection across the square's vertical middle line. Composing two of these symmetry functions gives another symmetry function. These symmetries determine a group called the dihedral group of degree 4 and denoted D4. The underlying set of the group is the above set of symmetry functions, and the group operation is function composition. Two symmetries are combined by composing them as functions, that is, applying the first one to the square, and the second one to the result of the first application. The result of performing first a and then b is written symbolically from right to left as

What sends a point in the square to the relating point under the symmetry? 
Answer: functions


Problem: The Eritrean highway system is named according to the road classification. The three levels of classification are: primary (P), secondary (S), and tertiary (T). The lowest level road is tertiary and serves local interests. Typically they are improved earth roads which are occasionally paved. During the wet seasons these roads typically become impassable. The next higher level road is a secondary road and typically is a single-layered asphalt road that connects district capitals together and those to the regional capitals. Roads that are considered primary roads are those that are fully asphalted (throughout their entire length) and in general they carry traffic between all the major towns in Eritrea.
What are the three levels of road classification in Eritrea?
The answer is the following: primary (P), secondary (S), and tertiary (T)


New Haven has a variety of museums, many of them associated with Yale. The Beinecke Rare Book and Manuscript Library features an original copy of the Gutenberg Bible. There is also the Connecticut Children's Museum; the Knights of Columbus museum near that organization's world headquarters; the Peabody Museum of Natural History; the Yale University Collection of Musical Instruments; the Eli Whitney Museum (across the town line in Hamden, Connecticut, on Whitney Avenue); the Yale Center for British Art, which houses the largest collection of British art outside the U.K., and the Yale University Art Gallery, the nation's oldest college art museum.[citation needed] New Haven is also home to the New Haven Museum and Historical Society on Whitney Avenue, which has a library of many primary source treasures dating from Colonial times to the present.
What is the name of the museum that specifically focus on a single inventor located the city?
the Eli Whitney Museum


Input: Namibia
Up to 1990, English, German and Afrikaans were official languages. Long before Namibia's independence from South Africa, SWAPO was of the opinion that the country should become officially monolingual, choosing this approach in contrast to that of its neighbour South Africa (which granted all 11 of its major languages official status), which was seen by them as "a deliberate policy of ethnolinguistic fragmentation." Consequently, SWAPO instituted English as the sole official language of Namibia though only about 3% of the population speaks it as a home language. Its implementation is focused on the civil service, education and the broadcasting system. Some other languages have received semi-official recognition by being allowed as medium of instruction in primary schools. It is expected of private schools to follow the same policy as state schools, and "English language" is a compulsory subject. As in other postcolonial African societies, the push for monolingual instruction and policy has resulted in a high rate of school drop-outs and of individuals whose academic competence in any language is low.

There was a high rate of what due to monolingual instruction?
Output: school drop-outs


Problem: Please answer a question about the following article about MP3:
A sample rate of 44.1 kHz is almost always used, because this is also used for CD audio, the main source used for creating MP3 files. A greater variety of bit rates are used on the Internet. The rate of 128 kbit/s is commonly used, at a compression ratio of 11:1, offering adequate audio quality in a relatively small space. As Internet bandwidth availability and hard drive sizes have increased, higher bit rates up to 320 kbit/s are widespread.
As technology advances, what is another higher bit rate that is beginning to spread?
A:
320 kbit/s
