Answer:
According to one version of the story, Laius, king of Thebes, was warned by an oracle that his son would slay him. ... Continuing on his way, Oedipus found Thebes plagued by the Sphinx, who put a riddle to all passersby and destroyed those who could not answer. Oedipus solved the riddle, and the Sphinx killed herself.
Explanation:
Okay so
passage 1: Passage one has a mostly positive tone. Allow me to explain. The words used can set a peaceful, calm mood and allow you to paint a beautiful picture in your mind. Words such as bobbed, lapped and quaint suggest calm movements and an enjoyable environment. However Passage 2 is mostly negative in tone. This scene, unlike passage 1 sets a miserable, dark mood, and seems like an unlikely place to be comfortable in. Words such as ragged, frigid, slapped and weathered suggests a worn raft, cold waters, and miserable conditions, perhaps life threatening. Therefore, it is negative in tone. To sum up everything previously stated, passage 1 has a mostly positive tone, whereas passage 2 is mostly negative.
hope that helped :]
