Read the excerpt from The Republic by Plato. You know, I said, that dyers, when they want to dye wool for making the true sea-purple, begin by selecting their white colour first; this they prepare and dress with much care and pains, in order that the white ground may take the purple hue in full perfection. The dyeing then proceeds; and whatever is dyed in this manner becomes a fast colour, and no washing either with lyes or without them can take away the bloom. But, when the ground has not been duly prepared, you will have noticed how poor is the look either of purple or of any other colour. Yes, he said; I know that they have a washed-out and ridiculous appearance. Then now, I said, you will understand what our object was in selecting our soldiers, and educating them in music and gymnastic; we were contriving influences which would prepare them to take the dye of the laws in perfection, and the colour of their opinion about dangers and of every other opinion was to be indelibly fixed by their nurture and training, not to be washed away by such potent lyes as pleasure—mightier agent far in washing the soul than any soda or lye; or by sorrow, fear, and desire, the mightiest of all other solvents. And this sort of universal saving power of true opinion in conformity with law about real and false dangers I call and maintain to be courage, unless you disagree. Which type of rhetorical device best supports the claim that soldiers need to be well educated and trained? a. ethos, because it shows how dyers have the tenacity to fight b. kairos, because it argues why soldiers need training immediately c. logos, because it discusses how that idea is similar to dyeing wool d. pathos, because it helps people feel protected by their soldiers
