Answer to Question 1

Black surfaces absorb the radiation incident on them. If the radiation is too
intense, it overwhelms the surface and the majority can be reflected. In this case, it can
appear white.

Answer to Question 2

Sometimes the Sun doesn't shine through clouds for days on end. This can
impact the output of solar hot water for household use. In addition, windmills depend on the
wind, which must be above a certain speed in order for the mill to generate electricity. If the
wind speed is below the threshold for substantial times, this can affect the availability of that
wind energy. In order to meet these exigencies, backup sources are necessary.

Dogs have been used in studies to detect various cancers in human subjects. They have been trained to sniff breath samples from humans that were collected by having them breathe into special tubes. These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).
