Problem: Clothing:

Clothing protects against many things that might injure the uncovered human body. Clothes protect people from the elements, including rain, snow, wind, and other weather, as well as from the sun. However, clothing that is too sheer, thin, small, tight, etc., offers less protection. Clothes also reduce risk during activities such as work or sport. Some clothing protects from specific environmental hazards, such as insects, noxious chemicals, weather, weapons, and contact with abrasive substances. Conversely, clothing may protect the environment from the clothing wearer, as with doctors wearing medical scrubs.

What does clothing protect from things which may injure it?
---
A: the uncovered human body


Problem: Niels Bohr introduced the first quantized model of the atom in 1913, in an attempt to overcome a major shortcoming of Rutherford's classical model. In classical electrodynamics, a charge moving in a circle should radiate electromagnetic radiation. If that charge were to be an electron orbiting a nucleus, the radiation would cause it to lose energy and spiral down into the nucleus. Bohr solved this paradox with explicit reference to Planck's work: an electron in a Bohr atom could only have certain defined energies En
What statement did Bohr make about the nucleus of an atom?

Some NPOs may also be a charity or service organization; they may be organized as a profit corporation or as a trust, a cooperative, or they exist informally. A very similar type of organization termed a supporting organization operates like a foundation, but they are more complicated to administer, hold more favorable tax status and are restricted in the public charities they support. Their mole is not to be successful in terms of wealth, but in terms of giving value to the groups of people they administer to.
What model do NPO's follow instead of being financially successful?
A: unanswerable


Context and question: On October 9, 2006 at 6:00 a.m., the network switched to a 24-hour schedule, becoming one of the last major English-language broadcasters to transition to such a schedule. Most CBC-owned stations previously signed off the air during the early morning hours (typically from 1:00 a.m. to 6:00 a.m.). Instead of the infomercials aired by most private stations, or a simulcast of CBC News Network in the style of BBC One's nightly simulcast of BBC News Channel, the CBC uses the time to air repeats, including local news, primetime series, movies and other programming from the CBC library. Its French counterpart, Ici Radio-Canada Télé, still signs off every night.
Was CBC one of the first or last stations to adopt a 24 hour schedule?
Answer: last


Question: Objections to banning the use of incandescent light bulbs include the higher initial cost of alternatives and lower quality of light of fluorescent lamps. Some people have concerns about the health effects of fluorescent lamps. However, even though they contain mercury, the environmental performance of CFLs is much better than that of light bulbs, mostly because they consume much less energy and therefore strongly reduce the environmental impact of power production. LED lamps are even more efficient, and are free of mercury. They are regarded as the best solution in terms of cost effectiveness and robustness.
Is there an answer to this question: What is regarded as the worst solution in terms of cost effectiveness and robustness?

Answer: unanswerable

In China, urbanization increased as the population grew and as the division of labor grew more complex. Large urban centers, such as Nanjing and Beijing, also contributed to the growth of private industry. In particular, small-scale industries grew up, often specializing in paper, silk, cotton, and porcelain goods. For the most part, however, relatively small urban centers with markets proliferated around the country. Town markets mainly traded food, with some necessary manufactures such as pins or oil. Despite the xenophobia and intellectual introspection characteristic of the increasingly popular new school of neo-Confucianism, China under the early Ming dynasty was not isolated. Foreign trade and other contacts with the outside world, particularly Japan, increased considerably. Chinese merchants explored all of the Indian Ocean, reaching East Africa with the treasure voyages of Zheng He.
What caused urbanization to increase in China?
A:
the population grew
