A. Distance education or e-learning offers several advantages. Students participating in e-learning programs are often able to set their own schedules and work at their own pace. The learning experience can be supported by multimedia such as videos, interactive websites, and real-time conferencing with experts from anywhere in the world. Additionally, e-learning programs are less expensive than traditional ones.
B. Jacob and Wilhelm Grimm did not expect to create a children’s collection of fairy tales. Instead, they wanted to preserve Germany’s oral tradition by collecting different stories. Not until several editions of their collection were published did the brothers realize that children were to be a major audience. Once the Brothers Grimm saw this new public, they tried to refine and soften their tales, which had originated centuries earlier as folklore.
C. The five Potter books have sold 250 million copies worldwide in 55 languages, including Latin and Ancient Greek. In Harry Potter and the Half-Blood Prince, J. K. Rowlings uses spells and charms that are largely based on Latin. But one of the most serious spells, Avada Kedavra, may be a variant of «abracadabra». In the Harry Potter series, it is a spell that causes death. Harry Potter is the only one known to have survived it.
D. Critics of the Harry Potter books point out that the main characters who are supposed to be «good» are consistently and regularly portrayed as breaking all manner of ethical rules like those against lying, cheating, and stealing.

E. On Christmas Eve of 1968, NASA astronaut William Anders, while orbiting the moon with the Apollo 8 mission, took a photograph that provided a foundation for the modern green movement. His photo shows a small, blue planet Earth peeking over the horizon of the Moon. The image of a small planet, alone in a vast ocean of space, showed billions of people the fragility of our planet and the importance of preserving and protecting Earth.
F. There are many indoor air pollutants that can be harmful. Indoor air can be up to 100 times more polluted than outdoor air. Organic compounds from some paints, carpets, synthetic fabrics and adhesives are a known health hazard, contributing to the disease known as Sick Building Syndrome. Proper technology can help — open windows to let fresh air in and bad air out.
G. Some people, especially in rural areas, burn their trash in pits or barrels. It seems an easy way to get rid of your garbage, but the smoke it creates has a lot of really unhealthy toxic chemicals. Burning things like foam cups, plastics, and colored and bleached paper in backyards or even fireplaces causes toxic smoke that can spread throughout the neighborhood.
