Practice Test 7

Keisha presents an inquiry project about whether background music affects studying. She says, “My main finding is that quiet instrumental music helped most students focus.” She then adds, “The critical finding is that lyrics distracted many students,” and she pauses after that sentence. She supports her findings by describing her class survey results and giving one example of a student comment about lyrics being distracting. Keisha speaks clearly, but she keeps her head down and reads every sentence from her slides.

Which technique would most improve Keisha’s delivery without changing her content?

Carlos presents research findings about cafeteria food waste. He states his claim: “The key point is that our cafeteria throws away the most unopened milk cartons.” He supports this by describing how he and a partner counted items in the trash for five days and found an average of 42 unopened cartons per day. Then he spends two minutes describing his favorite lunch, the cafeteria posters, and the color of the trash bins without explaining how those details support his claim. Carlos speaks at an adequate volume and has clear pronunciation, but he only makes eye contact at the very beginning.

Which evaluation best explains the quality of Carlos’s support and delivery?
