Explanation

The geneticists mentioned are studying a population descended from a rather small number of people a rather long time ago.

Geneticists — who study genes, of course — would be interested in how this population changed over time (mutated) and became different from one another (diversity). Note that none of the other answers are logical at all.

Hence options diversity, mutation are best fit!

Was difficult to narrow down between diversity/revivification. Please explain.

Shouldn't the answer be B. revivification and F. rejuvenation as Iceland has been able to repopulate from less than 1000 ancestors? That doesn't seem diverse.

fell for B/F since the citizens are descendants of those who survived from the illness. Hmm.. is it because we don't know if they survived through rejuvenation or they were just immune to it from the first place? If applied the same logic, answer choices diversity and mutation are hard to narrow.
