□ he tested the water and found that it was polluted.
□ he made other products, like soap and molasses, out of unwanted crops.
□ he tested the soil and found that nitrogen needed to be added.
□ he changed the cells and dna of the crops.

Explanation:

George Washington Carver used agricultural chemistry to support Black Southern farmers by analyzing soil nutrient deficiencies (specifically identifying nitrogen needs) and developing alternative uses for surplus/unwanted crops to create marketable products, increasing farmers' income and crop sustainability. The other options are incorrect: he did not focus on water pollution testing, and genetic modification of crop DNA was not a practice in his era.

• He made other products, like soap and molasses, out of unwanted crops.
• He tested the soil and found that Nitrogen needed to be added.
