The farmer observed more tomatoes on the plants with his fertilizer.
They were also bigger than the other plants. The supply company
claims the farmer’s study is invalid. What scientific reason does the
company have to make this claim?
A. The farmer’s study did not include data on
the height of the plants.
B. The farmer did not promote his fertilizer to
enough companies to receive an offer.
C. The farmer needed a chemist to write out the
chemical formula
D. The farmer’s study should have included a
larger sample of plants and multiple fertilizers
