Read the passage:
"I don't think I like boys," answered the Swallow. "Last summer, when I was staying on the river, there were two rude boys, the miller's sons, who were always throwing stones at me. They never hit me, of course; we swallows fly far too well for that, and besides, I come from a family famous for its agility, but still, it was a mark of disrespect."
Which provides the best evidence that the Swallow is boastful?
"I don't think I like boys," answered the Swallow.
"They never hit me, of course."
"Last summer, when I was staying on the river . . ."
"It was a mark of disrespect."
