In the second paragraph of the passage, the writer uses sentence variety to structure the paragraph and add impact to the description of the Australian outback. The first sentence is a short, punchy dialogue that sets the scene and introduces the pilot. The second sentence is a longer, more descriptive sentence that uses sensory details to paint a vivid picture of the environment. The third sentence is a short, fragmented sentence that emphasizes the physical discomfort of the narrator. The fourth sentence is a longer sentence that provides more information about the location and time of year. Together, these sentences create a rhythm and flow that draw the reader into the story and help them visualize the setting.
