Explanation:
In the essay "Outsmart Your Smartphone", the author Vickie Milazzo supports and strengthens her claim by openly recognizing how smartphones and social media can be fun and relaxing sometimes.
With lines like "Smartphone apps make it fun and easier than ever to read our friends’ status updates and to see the photos they’ve posted" and "it’s like experiencing hugs all day long.", she admits how smartphones can be fun and interesting.
The author adds these counter arguments because it is evident and true that sometimes smartphones can be helpful to users. She then reminds the readers of the bad effects of using too much of smart phones with lines like "F acebook and T witter won’t be evaluating your work performance and probably can’t qualify you for a raise either".
In this way, she supports and strengthens her claim by openly recognizing the importance of smartphones as well as reminding the readers of its drawbacks.
