Which of these best describes what emily has learned about life when she asks the stage manager at the end of act iii, "do any human beings ever realize life while they live it? -every, every minute? " that death is the only significant event in life that life is fleeting and insignificant that life is full of ordinary, uninteresting moments that we take life for granted rather than valuing every minute

that we take life for granted rather than valuing every minute

Explanation:

What Emily means is that life is fleeting and we often do not value moments that are too special, but we forget that these moments are unique, so when we let those moments pass we are not living fully. For this reason, the best answer to this question is "  that we take life for granted rather than valuing every minute"

the speech this question is referring to is president kennedy's special message to the congress on urgent national needs, may 25, 1961

kennedy responds in a very direct and concrete way to those thinking that communism is a positive system:

"yet their aggression is more often concealed than open. they have fired no missiles; and their troops are seldom seen. they send arms, agitators, aid, technicians and propaganda to every troubled area. but where fighting is required, it is usually done by others--by guerrillas striking at night, by assassins striking alone--assassins who have taken the lives of four thousand civil officers in the last twelve months in vietnam alone--by subversives and saboteurs and insurrectionists, who in some cases control whole areas inside of independent nations." (kennedy)

president kennedy presents communism as cowardly, as a hidden and treacherous weapon that strikes from the shadows like thieves, he represents the system as not even being capable of showing and open and overt attack or confrontation. to finish up the response, he expresses that the system attacks even a country's idependence and freedom.
