A scientist investigates and suggests this relationship is only partly true. Which of the following best describes what the scientist discovered?
A) Most of the money saved by using ethanol is used by charitable organizations that feed the poor.
B) The process of making ethanol also produces antibiotics to help prevent human diseases.
C) Although corn prices have risen, much more corn is being planted, and corn used for ethanol production still yields useful food products.
D) Ethanol production uses part of corn not used to feed either animals or humans.
