Nine bean plants were grown in varying amounts of light. Mark thinks that, if the light is too intense, a bean plant will not grow as
high.
Is Mark's prediction correct?
Yes; the tallest plants were the ones that got the weakest light.
No; some plants grew just as well while getting very strong light.
Yes, when the light was too strong the plants did not grow as well.
No: plants that got the strongest light were also the ones that grew best.
