Read the excerpt from The Republic by Plato.

Let us then consider, first of all, what will be their way of life, now that we have thus established them. Will they not produce corn, and wine, and clothes, and shoes, and build houses for themselves? And when they are housed, they will work, in summer, commonly, stripped and barefoot, but in winter substantially clothed and shod. They will feed on barley-meal and flour of wheat, baking and kneading them, making noble cakes and loaves; these they will serve up on a mat of reeds or on clean leaves, themselves reclining the while upon beds strewn with yew or myrtle. And they and their children will feast, drinking of the wine which they have made, wearing garlands on their heads, and hymning the praises of the gods, in happy converse with one another. And they will take care that their families do not exceed their means; having an eye to poverty or war.

Read the excerpt from Utopia by Sir Thomas More.

Throughout the island they wear the same sort of clothes, without any other distinction except what is necessary to distinguish the two sexes and the married and unmarried. The fashion never alters, and as it is neither disagreeable nor uneasy, so it is suited to the climate, and calculated both for their summers and winters. Every family makes their own clothes; but all among them, women as well as men, learn one or other of the trades formerly mentioned.

Which rhetorical device do both Plato and More use in these excerpts?

They use kairos by establishing the importance of addressing their arguments now.
They use ethos by providing examples of how their suggestions have been successful.
They use pathos by stressing emotional language to convince others to agree with them.
They use logos by describing the practical importance and benefits of their arguments.
