Read the comment from a group member during a discussion about whether or not people need to exercise more.'I think it all depends on the people. Some people eat too many bad foods and also don't exercise enough. They gain weight. Other people go to the gym and probably spend too much time there. Also, other people exercise just enough.'What are the key ideas of the comment?

After a person speaks in a group discussion, every member should be able to review what was said. Also, a member should be able to give their own ideas that pertain to what the previous speaker said. The ideas should link together. In this case, the discussion would flow smoothly.
