Which of the following is a possible effect of being a child of a holocaust survivor experienced by the speaker in the poem “tattoo” by gregg shapiro?
survivor’s guilt
overconfidence
longer-than-normal childhood
depression

The best answer is: survivor's guilt.
This is a bit paradoxical, since the speaker is not a survivor in the strict sense, but the father is, 

But, it's the best answer. For example, the speaker says "If I could trade places with him" - showing that the speaker feels guilty for not taking the place of the father.

It could be anything, recent improvements in technology/telecommunication/internet have increased the pace of globalization.generally, it has something to do with technology. globalization means that people around the world are brought together through technology which speeds things up. so maybe some of those options could be correct. : )
