Read the excerpt below from the poem “Ulysses” by Alfred, Lord Tennyson, and answer the question that follows. Old age hath yet his honour and his toil;Death closes all; but something ere the end,Some work of noble note, may yet be done,Not unbecoming men that strove with Gods.The lights begin to twinkle from the rocks:The long day wanes: the slow moon climbs: the deepMoans round with many voices. Come, my friends,‘Tis not too late to seek a newer world.Push off, and sitting well in order smiteThe sounding furrows; for my purpose holdsTo sail beyond the sunset, and the bathsOf all the western stars, until I die.It may be that the gulfs will wash us down:It may be we shall touch the Happy Isles, And see the great Achilles, whom we knew.Tho’ much is taken, much abides; and tho’We are not now that strength which in old daysMoved earth and heaven; that which we are, we are;One equal temper of heroic hearts,Made weak by time and fate, but strong in willTo strive, to seek, to find, and not to yield.
