A year ago, I got correction for "a starting member", not "a starting lineup", so I think the first sentence should be "Is Ji-sung Park in the starting lineup?" as "starting lineup" is a group, not an individual. What do you think?
Also. "great goal" should be corrected to "a great goal", isn't it?
Jihun : Is Ji-sung Park a starting lineup?
Bora : Yes, he is doing well. Ji-sung, Go!
Jihun : Wow! Did you see? It was great goal.
Bora : Haha! His goal celebration is very funny!
