Read the passage. Social media is here to stay. No amount of complaining by a generation who cannot even turn on a computer will change the fact that we live in a social media world. Increasing access to social media for people who are unfamiliar with it or afraid of using it should be the first step toward making the playing field a bit more even for everyone. The author is thinking of adding one of these sentences to the end of the passage. Which sentence contains a fallacy? My hope is that our generation can be the generation to create a path to social media success. Unless everyone in the U.S. including our grandparents can successfully use social media, we will be left behind. Not everyone needs to have the same passion for social media, but access is nonetheless important. Success for beginners, through access, will lead to a more aware and active community of users.
