The correct answer to this open question is the following.
One area in the text in which the author supports her main point with evidence is when the author decides to make a reference to the article published in the Journal of Social Relationships.
The author comments that in the article published, the issue s that electronic devices such as smartphones, tablets, and more, have changed the way people relate to each other in family environments like having a nice hot dinner in a restaurant.
It is common to be in a restaurant and see the other tables with families that instead of being having warm conversations, they are each other focused on their mobile phones. And that is a shame.
That is why is the article "Turning Off, Dining In," the author refers to the importance of having quality time with the devices turned off in order to have a nice family time, the way it used to be.
