Farmers who use genetically engineered plants on a large scale are at great financial risk because at any time a study could be published that would undermine what little confidence consumers have in genetically engineered foods. It is unwise for farmers to grow such crops. They do not fetch a high enough price to compensate for the risk. Which one of the following most accurately expresses the conclusion of the argument as a whole? ['A study could come out at any time that would greatly undermine public confidence in genetically engineered foods.', 'A farmer who grows genetically engineered crops on a large scale is taking a financial risk.', 'It is not prudent for a farmer to grow genetically engineered crops.', 'The price paid for genetically engineered crops does not compensate for the financial risk farmers incur by growing them.']
