What time is it? That simple question probably is asked more
often today than ever. In our clock‐studded, cell‐phone society,
the answer is never more than a glance away, and so we can
blissfully partition our daysinto eversmaller incrementsfor ever
5 more tightly scheduled tasks, confident that we will always
know it is 7:03 P.M.
Modern scientific revelations about time, however, make
the question endlessly frustrating. If we seek a precise
knowledge of the time, the elusive infinitesimal of “now”
10 dissolves into a scattering flock of nanoseconds. Bound by the
speed of light and the velocity of nerve impulses, our
perceptions of the present sketch the world as it was an instant
ago—for all that our consciousness pretends otherwise, we can
never catch up.
15 Even in principle, perfect synchronicity escapes us. Relativity
dictates that, like a strange syrup, time flows slower on moving
trains than in the stations and faster in the mountains than in
the valleys. The time for our wristwatch or digital screen is not
exactly the same as the time for our head.
20 Our intuitions are deeply paradoxical. Time heals all
wounds, but it is also the great destroyer. Time is relative but
also relentless. There is time for every purpose under heaven,
but there is never enough.

No texto, a pergunta “What time is it?” (L. 1), inserida no debate da ciência moderna sobre a noção de tempo,
corrobora a crença de que a passagem do tempo é uma garantia de renovação para a humanidade.

representa a obsessão dos seres humanos pelo controle da vida com auxílio do relógio.
revela o esforço empreendido pelas pessoas na distribuição das tarefas ao longo do dia.
mostra o descompasso e a imprecisão relativos à percepção do presente e do passado.
Gabarito:
mostra o descompasso e a imprecisão relativos à percepção do presente e do passado.
No texto, lemos que "presos à velocidade da luz e à velocidade dos impulsos nervosos, nossas percepções do presente esboçam o mundo como era há um instante atrás" (" Bound by the speed of light and the velocity of nerve impulses, our perceptions of the present sketch the world as it was an instant ago"). Por isso, a pergunta "What time is it?" mostra o descompasso e a imprecisão relativos à percepção do presente e do passado (alternativa E).
