Read the following passage and choose the option (A, B, C or B) that best answers each of the questions below. One of the most obvious negative aspects of social networking is losing face- to-face contact with other people. Teens are sitting around with their phone in their hands all day long, tapping messages onto screens instead of communicating with real people. Many teenagers feel more comfortable with virtual friends than with real ones. The majority think that it is easier to chat on the Internet because they lack communication skills. It is also true that parents often have no knowledge about what their kids do with their phones or computer. Crosby says that, "While kids are plugged in to social media, only about 40% of parents are involved themselves." And because parents don't know the full picture, they also don't know how to deal with a teenager's potential overuse of social media and might not even be aware that a problem exists. Therefore, social networking can be much more immediately engaging with the teenager's life than parents are, and this fact makes virtual communication feels more "real" than face-to-face communication.
