While researching a topic, a student has taken the following notes:
<ul> <li>Baleen whales filter feed using comb-like plates.</li> <li>The plates are made of keratin, the same material as fingernails.</li> <li>Whales swallow large volumes of seawater.</li> <li>The seawater is then expelled through the baleen.</li> <li>Krill and small fish remain trapped on the baleen and are swallowed.</li> </ul> The student wants to summarize how baleen feeding works for an audience unfamiliar with it. Which choice most effectively uses relevant information from the notes to accomplish this goal?Which choice most effectively makes the student's point?
