Exercise 1 - solution

Arabica does best with:
- Altitude: usually cultivated at 1,200 to 1,500 m
- Temperature: average of 15 to 24 C (tolerates cold, not frost)
- Rainfall: 1.2 to 1.8 m a year, evenly distributed

Why "must be grown at 1,200 to 1,500 m" is too strong: that range is where arabica is usually cultivated, not a limit. The article says some plantations grow it from sea level up to 2,800 m.
