Question

gathering evidence for one side of an argument
most teens believe that their social networking sites have little impact, positive or negative, on their social and emotional welfare. approximately 70 - 80 percent of respondents reported that their use of social media does not generally influence their self - worth, self - confidence, how popular they feel, or their level of empathy felt for others.
fifteen to 30 percent of teens stated that social networking did have a positive effect on their social and emotional well - being - they reported feeling less shy, more outgoing, more self - confident, more popular, more sympathetic to others, and better about themselves.
a much smaller percentage of respondents, approximately 5 percent, reported that social media made them feel more depressed, less popular, less confident, and worse about themselves.

• impact of social media on teens well - being,

which detail supports an argument that technology brings some teens together because it improves their social lives?
“most teens believe that their social networking sites have little impact, positive or negative, on their social and emotional welfare.”
“fifteen to 30 percent of teens... reported feeling less shy, more outgoing, more self - confident, more popular”
“approximately 5 percent, reported that social media made them feel more depressed”

Explanation:

The argument is that technology (social networking) brings teens together by improving their social lives. The second option shows positive social - related impacts (less shy, more outgoing etc.) which directly support the idea of improvement in social lives. The first option says there is little impact (so it doesn't support the argument of improvement) and the third option shows a negative impact (depression).

Answer:

"Fifteen to 30 percent of teens... reported feeling less shy, more outgoing, more self - confident, more popular"
