Which statement about genetically modified (GM) foods is false?

• A. Scientists have used genetic modification, in various forms, as a means of improving crop yields, crop quality, and pest resistance for many years.
• B. Genetic modification includes products made by artificial mutagenesis and by non-natural crosses between unrelated spscies.
• C. A major difficulty in labelling foods as GM-free is that it is virtually impossible to measure genetically modified DNA or protein molecules in most food made from GM crops.
• D. The recent decision by McCain foods to stop processing GM potatoes means that they will eventually use less pesticides to produce the potatoes that are required to make fries.
• E. A major environmental concern with GM crops is that engineered genes will escape into the environment, resulting in the origin of superweeds (aggressive undersirable plant species).
