The correct answer is C) The future leader was still a very young man although he joined a war party against the Utes. This sentence has an incorrect structure as it uses the <em>conjunction although </em>where it is not necessary. The second part of the sentence is not subordinated to the first part. In other words, the fact that the leader joined the war party does not depend on the fact that he was very young when he did it.
Nausicaa is worried that rumors may be started about her and a man. Usually as a child, or as a grown woman there would not be many severe consequences, however, Homer clearly states that Nausicaa is of the marrying age and with this comes the responsibility of not only her honor, but the honor of her royal blooded family. This shows that she is a thoughtful girl who is wise and has benevolent intentions.
