Read the passage from "ode on a grecian urn."

fair youth, beneath the trees, thou canst not leave
thy song, nor ever can those trees be bare;
bold lover, never, never canst thou kiss,
though winning near the goal—yet, do not grieve;
she cannot fade, though thou hast not thy bliss,
for ever wilt thou love, and she be fair!

the word from the passage that best defines the topic is

"youth."
"song."
"kiss."
"love."
