In the context of "The Pearl" by John Steinbeck, Kino is particularly worried when he spots b. the trackers. The trackers pose a significant threat to him and his family as they are hunting for him due to the events that unfold after the discovery of the pearl. The trackers represent danger and a sense of impending doom for Kino, making them a primary source of his anxiety.
