Read the excerpt from Parvati's argument in favor of using cell phones in class. Today's cell phones are not just phones; they are little computers. That means they are effective research tools. Students can use them to access dictionaries, encyclopedias, and other reference materials. They can search for articles, videos, and images. In my civics class, our teacher even held mock elections, and we voted using our cell phones. What is the best evaluation of Parvati's evidence? It is irrelevant and insufficient, because she discusses using computers rather than phones. It is irrelevant and insufficient, because her evidence relies solely on her own experience. It is relevant and sufficient, because she gives convincing examples of how phones support classwork. It is relevant and insufficient, because she provides general reasons without specific examples.
