Is it sub 600 ? you have to read in between the lines for this.
C says "Children who do not spend all
of their after-school hours texting friends spend at least some of that time in oral conversation
with other people."
Now the argument says
"When a child is texting his friends and not actually getting on the phone to talk or not interacting in person directly, that child is losing out on interpersonal communication skills
: Therefore, children who spend their spare time texting their friends have less experience in oral communication than other children have."The missing link :
Now the conclusion can hold if the child in his spare time does partially
use oral communication to develop his interpersonal skills when he is not texting. Note: This is required because if we do not assume this, we can never conclude that the children who spend their time texting have less experience in oral communication. Example scenario:- If a child does not text, he might indulge in playing computer games, hence, he would not be better off than those who text. But, if he spends his spare time (even a small amount) in oral communication, he will be better off than those children who spend all their time in texting.
--It's one thing to get defeated, but another to accept it.
