"It's great to be able to keep in contact with so many people with the click on  the button."

Explanation:

The questions above is related to the article entitled "Social Networking Sites," written by T.C. Henderson. It talks about the preoccupation of people with social networking sites like "Headnovel" and "MyDisgrace."  

Among the choices above, "It's great to be able to keep in contact with so many people with the click on  the button" shows that social networking sites can be impersonal.
