"Give a man a fish and you feed him for a day; teach a man to fish and you feed him for a lifetime." Translate this proverb into Mandarin and briefly explain.
Explain why a strong correlation would be found between weekly sales of firewood and weekly sales of cough drops over a 1-year period. Would it imply that fires cause coughs?
In this case, people tend to buy more firewood to heat up the house in cold weather and cold weather more easily leads people to catch colds and have sore throats and thus buy more cough drops. No, it would not imply that fires cause coughs because correlation does not imply causation.
