Sirius found quite a bit about Muggle culture fascinating though . It was while watching the events that Harry wondered what he would be able to compete at . Surely not Gymnastics . He did not have the grace for that . He was an alright swimmer , but nothing that would make him stand out against anyone else .

Question: What might be the reason Harry had no idea what he could compete at ?
Answer: Harry had never participated in any sport so he did n't know what he could do .Harry was the fastest swimmer in town but had never competed .Harry was a true athletic but he did n't know how to compete .Harry was very graceful but he had never done gymnastics .
