Which set of lines in this excerpt from w. b. yeats's "an irish airman foresees his death" suggests that the speaker's choice to become an airman in the war was influenced by his perception of the futility of life? i know that i shall meet my fate somewhere among the clouds above; those that i fight i do not hate, those that i guard i do not love; my country is kiltartan cross, my countrymen kiltartan's poor, no likely end could bring them loss or leave them happier than before. nor law, nor duty bade me fight, nor public men, nor cheering crowds, a lonely impulse of delight drove to this tumult in the clouds; i balanced all, brought all to mind, the years to come seemed waste of breath, a waste of breath the years behind in balance with this life, this death.

Read this excerpt from i never had it made. "it's all that ought to count," he replied. "but it isn't. maybe one of these days it will be all that counts. that is one of the reasons i've got you here, robinson. if you're a good enough man, we can make this a start in the right direction. but let me tell you, it's going to take an awful lot of courage." he was back to the crossroads question that made me start to get angry minutes earlier. he asked it slowly and with great care. "have you got the guts to play the game no matter what happens? " "i think i can play the game, mr. rickey," i said. the next few minutes were tough. branch rickey had to make absolutely sure that i knew what i would face. beanballs would be thrown at me. i would be called the kind of names which would hurt and infuriate any man. i would be physically attacked. could i take all of this and control my temper, remain steadfastly loyal to our ultimate aim? which is the central idea of this excerpt?
