Read the excerpt from the odyssey. but when he knew he heard odysseus' voice nearby, he did his best to wag his tail, nose down, with flattened ears, having no strength to move nearer his master. and the man looked away, wiping a salt tear from his cheek: but he hid this from eumaeus. which theme do these lines support? loyalty and fidelity are precious traits. overconfidence can lead one to danger. making snap judgments is often very unwise. love and family make a homecoming worthwhile.

The right answer is the A) Loyalty and fidelity are precious traits.

Explanation: Just to elaborate a little on the answer, it can be added that this famous excerpt relates the moment in which Argos, Odysseus's dog, recognized him after years of absence. Argos was by then an old dog, so he did not have much strength left, but he managed to thump his tail, drop his ears, and nuzzle in recognition of his master's presence, which he perceived through his voice. This precious gesture moved Odysseus to tears.
