Read the opening paragraph of a story:
I stepped out of the time machine. Around me, I saw wide-
brimmed hats, smart dresses, and 1940s cars. A
handsome young man stood there, clearly awaiting my
arrival. "Hello," he said. "I'm your grandfather."
Based on this opening paragraph, which of the following outcomes is most
likely?
O
A. It will require the main character to make choices that will affect
the future.
O
B. It will involve deep conflict between the main character and her
grandfather
O
C. There will be a spiritual struggle for the main character.
O
D. The main character will meet herself on the day that she is born.

If he's meeting his grandfather for the first time, then it's likely that he went to the past. So... It could be A (Don't take my full word for it) No matter what happens, he's going to be affecting the future. If he didn't, then it'd be a paradox, and that just gets even more confusing. Considering the grandfather is a "young man", I would say it's safe to assume that he won't be meeting himself while he's there. Answer (A) is inevitable here.
