Jorge, I need your help! (‚ve just taken a class at Oaksterdam, and we bought your books for the class and referred to them for our take-home final exam.

The question (‚m wondering about went as follows:

Cannabis plant cultings root best at:

a) 85°F and 65% humidity

b) 60°F and 65% humidity

cl 95°F and 75% humidity

d) 90°F and 50% humidity.

None of them appeared right to me, but the cor­rect answer was supposedly a). What would you have put down?
