Task: Question Generation
Input (English): Background Paragraph: Protozoa generally feed by engulfing and digesting other organisms. As consumers, they have various roles in food chains and webs. Some are predators. They prey upon other single-celled organisms, such as bacteria. In fact, protozoa predators keep many bacterial populations in check. Other protozoa are herbivores. They graze on algae. Still others are decomposers. They consume dead organic matter. There are also parasitic protozoa that live in or on living hosts. For example, the protozoan that causes malaria lives inside a human host. For their part, protozoa are important food sources for many larger organisms, including insects and worms. 
Story: Students learned about protozoa in school this week. Dan and Jim were interested and read more on the subject. Dan read more about predatory protozoa, while Jim read more about herbivore protozoa.
Output (English): Which student read less about protozoa preying upon bacteria?
