问题    A question that health conscious consumers may ask when buying produce is whether they are free of pesticides. But currently, there is no federal standard for pesticide free "organically grown" foods grown without synthetic pesticides or fertilizers. The result, says U.S. Senate Agriculture Committee Chairman Patrick Leahy, is that consumers "too often see confusing and unsubstantiated claims such as ’ organically grown’ and ’ natural’ ".
   Currently, 22 states have some kind of certification program or at least requirements for third party certification. Look for the words "certified organically grown" or similar wording. In most cases, that means that no synthetic pesticides have been used in three years and that no synthetic fertilizers have been used in two or three years. Even if your State does not have its own program, you may have seen organically grown produce in the marketplace. If you want to know exactly what that means, ask the store’ s manager or the produce buyer about how the store’ s "organic" produce was grown.
   Legislation to establish a natural standard for organically grown produce is making its way through Congress. The US. Department of Agriculture would be responsible for the certification program. The legislation also would establish standards for processed foods claiming organic ingredients. But in the meantime, if you want to be certain that the produce you eat is pesticide free, you have two options. You can buy your fruits and vegetables from someone you know or you can grow your own.
What is the main idea of the text?

选项 A、organically grown foods are nutritious.
B、how to buy organically grown foods.
C、what does organically grown foods mean?
D、a general standard should be established to regulate the organically grown produce.

答案D
