In Dunn's article, the passage where I learned something new is on page 279 where he states that his friend and his team had discovered antibiotic-resistant bacteria in flies that congregate around pig farms. . Dunn overlooks the study's nuances; perhaps the actual number and types of tests performed, so that the non-scientific reader can understand the magnitude of the problem.2. The role of the questions in Dunn's article is to persuade the reader to think about their own role or responsibility in the flies' behavior. The first question he asks is: "Where do houseflies pick up these other bacteria, the ones they return to us in vomit, feces and footprints?" This question is at the heart of its main idea. He poses a second question about the discovery made by his friend named Coby, on pig farms, asking: But why do flies on pig farms tend to have antibiotic-resistant bacteria? Drawing attention once again to the current problem that we humans are largely responsible for the dangers that flies pose to our planet.
