Include Multimedia to Clarify Claims Practice Test

Yuki argues that the school library should stay open one hour later. She shares two statistics (how many students stay after school and how many books are checked out after 3:00), but she only says the numbers out loud. She wants the audience to believe the demand is high. Which multimedia would best strengthen her evidence?

Emma gives a 3-minute persuasive presentation arguing that the school should start composting cafeteria waste. She explains what composting is, lists three steps (collect scraps, mix with leaves, turn the pile), and claims it could cut cafeteria trash by “almost half,” but she uses only a title slide and then speaks with no other visuals, data, or examples. Which change would best add multimedia that clarifies her process and strengthens her claim?
