‘No, I think it’s pretty easy, Nick, It all depends.”’
Why did the father add “It all depends” after he answered his son’s question?
【正确答案】：

WHEN THE FATHER SAYS THAT DYING IS PRETTY EASY, HE MIGHT BE THINKING ABOUT THE SELF-MURDERED HUSBAND. BUT WHEN HE REFLECTS ON THE WIFE'S MIRACLE SURVIVAL OF THE VIOLENT PAIN IN THE WHOLE PROCESS OF BIRTH, HE ADDS THE FINAL SENTENCE: DYING IS BOTH HARD AND EASY, IT ALL DEPENDS ON INDIVIDUALS. 

【题目解析】：当父亲说死亡很容易时，他是针对自杀的丈夫来讲的。但是当他想到妻子能忍受生产的剧痛并奇迹般生还时，他又补充道：死亡因人而异，对珍惜生命的人来说死亡是困难的，因为他们能历经磨难而生还，而对自杀的人来说却很简单。
