Task: Question Answering
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: Reed started studying protozoa and was more interested in the predatorial behaviors of protozoa, while Brad wanted to know more about other types of protozoa, suck as grazers and decomposers. 
Question: Which person learned less about protozoa that consume dead organic matter?
Output (English): Reed.
