The sentence of this excerpt that gives a sense of Stephen's reluctance to take part in sports is:
<em>He kept on the fringe of his line, out of sight of his prefect, out of the reach of the rude feet, feigning to run now and then. </em>
This sentence conveys the idea that, although the character is on the brink of getting involved, he does not actually take part. Rather than that, he tries to remain invisible for the ones that are, in fact, involved.
I would say passage 1. Expository text is a non fiction writing meant to inform. It is all facts. The only other one i would consider is passage 3.
