Question

1. hiroshima: city :: nourishment:

racial bias
propaganda
sustenance

Explanation:

The analogy here is about finding a word with a similar meaning (synonym). "Hiroshima" is a type of "city", so we need a word that is a synonym of "nourishment". "Sustenance" means the same as nourishment (something that provides nourishment or support), while "racial bias" is about prejudice and "propaganda" is about spreading ideas, neither related to nourishment.

Answer:

C. sustenance
