Which sentence demonstrates no flaws in logic? a) people who oppose this requirement don’t understand that if we don’t start making service-hours a requirement that in the future, charities will run out of volunteers and stop serving those in need—possibly resulting in a rise in our nation’s crime rate! b) i would also ask people who oppose a service-hour requirement for graduation to realize that doing service hours also increases a student’s gpa over time! c) it is vital that we keep this from happening by making students learn to serve others now while they are still young and impressionable. d) in short, there are no real downfalls to requiring service hours as a graduation requirement.
