Answer:
I think the central idea of the passage is that the family Otzi's father is common in Europe.
Explanation:
My justification for my answer is that his DNA kind of matched the one of the people living in the Neolithic Age. This shows that maybe he was a descendant of those people.
I think the first answer is wrong because people of the Neolithic Age were from the past and I don't think DNA existed by then.
And the think the second is wrong because his mother's family was just rare it wasn't complex.
Finally the last is wrong because the DNA wasn't so hard to test it was also easy to compare it because there were other samples to be compared with.
That leaves us with the last answer as correct.
