Wheat was one of the first plant crops that humans domesticated. In the process of domestication, the wild form of wheat was eventually changed into a form more suited to human agricultural practice. Early farmers most likely used seeds only from wheat plants with — A) larger grains that could produce more food per plant B) taller stems that could block sunlight from weeds growing at ground level C) larger flowers that could be sold for additional income D) thinner stems that could endure heavy winds
