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?

Hey Moneymafia100!

Is there some part of this question that is missing? Maybe the options for the multiple choice?

But, pretty much what is happening in this part of the book is, Argo (Odysseus' dog) has seen Odysseus for the first time in a long time, and he is extremely old and weak. When he sees Odysseus he ends up dying, making this one of the saddest parts of the book - all Argo wanted was to see Odysseus once more, and then he would be able to die happy.

Hope I was able to help. And if you do have any multiple choice or bank of options, please let me know so I can further assist you!
