Task: Question Generation
Input (English): Background Paragraph: As for the public health or food safety concern, organic foods are intended to be healthy, free of contaminations and free from agents that could cause human diseases. Organic milk is meant to have no chemical residues to consumers, and the restrictions on the use of antibiotics and chemicals in organic food production has the purpose to accomplish this goal. Although dairy cows in both organic and conventional farming practices can be exposed to pathogens, it has been shown that, because antibiotics are not permitted as a preventative measure in organic practices, there are far fewer antibiotic resistant pathogens on organic farms. This dramatically increases the efficacy of antibiotics when/if they are necessary. 
Story: Two farmers sold their produce and milk on a large nearby market. John practiced organic farming and also produced organic milk, while Danny sold non-organic produce and milk.
Output (English): Which farmer sold fewer foods free of contaminations?
