Explanation:

Parvati's argument in favor of using cell phones in class is valid and sufficient. The evidence she presents is strong - she claims that cell phones are useful research tools that enable us to find the right piece of information. She also provides specific examples and even explains a situation in her class where cell phones were used. This makes her argument convincing, because she supports her claim with solid evidence.
