Problem: Red:

Red played an important role in Chinese philosophy. It was believed that the world was composed of five elements: metal, wood, water, fire and earth, and that each had a color. Red was associated with fire. Each Emperor chose the color that his fortune-tellers believed would bring the most prosperity and good fortune to his reign. During the Zhou, Han, Jin, Song and Ming Dynasties, red considered a noble color, and it was featured in all court ceremonies, from coronations to sacrificial offerings, and weddings.

How many elements did the Chinese philosophers think the world was made of?

A: five

Problem: Serological methods are highly sensitive, specific and often extremely rapid tests used to identify microorganisms. These tests are based upon the ability of an antibody to bind specifically to an antigen. The antigen, usually a protein or carbohydrate made by an infectious agent, is bound by the antibody. This binding then sets off a chain of events that can be visibly obvious in various ways, dependent upon the test. For example, "Strep throat" is often diagnosed within minutes, and is based on the appearance of antigens made by the causative agent, S. pyogenes, that is retrieved from a patients throat with a cotton swab. Serological tests, if available, are usually the preferred route of identification, however the tests are costly to develop and the reagents used in the test often require refrigeration. Some serological methods are extremely costly, although when commonly used, such as with the "strep test", they can be inexpensive.
What does the binding set off that will result in something visibly obvious in various ways?

Answer: a chain of events

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Eritrea's ethnic groups each have their own styles of music and accompanying dances. Amongst the Tigrinya, the best known traditional musical genre is the guaila. Traditional instruments of Eritrean folk music include the stringed krar, kebero, begena, masenqo and the wata (a distant/rudimentary cousin of the violin). The most popular Eritrean artist is the Tigrinya singer Helen Meles, who is noted for her powerful voice and wide singing range. Other prominent local musicians include the Kunama singer Dehab Faytinga, Ruth Abraha, Bereket Mengisteab, Yemane Baria, and the late Abraham Afewerki.
What instrument does Yemane Baria play?
A: unanswerable

Context and question: Usually a Presbyterian church will not have statues of saints, nor the ornate altar more typical of a Roman Catholic church. Instead, one will find a "communion table," usually on the same level as the congregation. There may be a rail between the communion table and the "Chancel" behind it, which may contain a more decorative altar-type table, choir loft, or choir stalls, lectern and clergy area. The altar is called the communion table and the altar area is called the Chancel by Presbyterians. In a Presbyterian (Reformed Church) there may be an altar cross, either on the communion table or on a table in the chancel. By using the "empty" cross, or cross of the resurrection, Presbyterians emphasize the resurrection and that Christ is not continually dying, but died once and is alive for all eternity. Some Presbyterian church buildings are often decorated with a cross that has a circle around the center, or Celtic cross. This not only emphasized the resurrection, but also acknowledges historical aspects of Presbyterianism. A baptismal font will be located either at the entrance or near the chancel area. Presbyterian architecture generally makes significant use of symbolism. You may also find decorative and ornate stained glass windows depicting scenes from the bible. Some Presbyterian churches will also have ornate statues of Christ or Graven Scenes from the Last Supper located behind the Chancel. St. Giles Cathedral ( Church Of Scotland- The Mother Church of Presbyterians) does have a Crucifix next to one of the Pulpits that hangs alongside. The image of Christ is more of faint image and more modern design.
What did Presbyterian churches have in them?
Answer: communion table

Question: Urban anthropology is concerned with issues of urbanization, poverty, and neoliberalism. Ulf Hannerz quotes a 1960s remark that traditional anthropologists were "a notoriously agoraphobic lot, anti-urban by definition". Various social processes in the Western World as well as in the "Third World" (the latter being the habitual focus of attention of anthropologists) brought the attention of "specialists in 'other cultures'" closer to their homes. There are two principle approaches in urban anthropology: by examining the types of cities or examining the social issues within the cities. These two methods are overlapping and dependent of each other. By defining different types of cities, one would use social factors as well as economic and political factors to categorize the cities. By directly looking at the different social issues, one would also be studying how they affect the dynamic of the city.
Is there an answer to this question: What division of anthropology is concerned with poverty?

Answer: Urban

Question: Since genomes are very complex, one research strategy is to reduce the number of genes in a genome to the bare minimum and still have the organism in question survive. There is experimental work being done on minimal genomes for single cell organisms as well as minimal genomes for multi-cellular organisms (see Developmental biology). The work is both in vivo and in silico.
Is there an answer to this question: What do scientists want a silico to do in the experiment?

Answer:
