Which of the following best explains the success of the central African rainfall-prediction technique of observing the waxing crescent Moon?
A) When the Moon is aligned in a U-shape, it can hold more water, so there is more rain. When it is tilted, it can hold less, so the weather is drier.
B) When the Moon is in Capricorn, there is always more tempestuous weather, while when in Pisces, it is just plain rainy.
C) Clouds cover part of the Moon's surface, so the smaller the crescent, the more likely it is to rain.
D) The Moon's orientation varies seasonally, and so does the weather.
E) The Moon causes the tides and affects the weather.
D
Process of Science: Assume we have data indicating a strong positive correlation between acupuncture treatments and recovery of patients from, say, cocaine addiction. However, let's also assume that every hypothesis we have for a mechanism of action (i.e., how acupuncture could work to help cure addiction) can be shown to be false. The patients, however, all claim to know that the acupuncture is what cured them. Which of the following conclusions are supported by our data?
