知音聽力 Interstellar Clouds - 英檢

請教關於知音聽力這題

正確答案是C

不過我不太懂為什麼

script 感覺是說生命出現的太突然了

要構成生命出現條件應該要花更多時間

但是答案看起來卻是已經花太多時間了

希望會的人可以解答一下

萬分感謝!!

script

Some argued that there just wasn't enough time;

time between when earth cooled and when life

emerged; that... uh... that complex self

replicating cells could not have developed that quickly.
