Analogy Solved: Sonora : Mexico :: Idaho : United States

The analogy follows a state-to-country relationship:

• Sonora is a state in Mexico (northwestern, capital Hermosillo).
• Idaho is a state in the United States (Pacific Northwest, capital Boise).

Therefore: Sonora is to Mexico as Idaho is to the United States.

Parallel Comparisons

• Both are large, mountainous, resource-rich states
• Both border the US/Mexico border region (Sonora directly; Idaho indirectly via Pacific Northwest)
• Both have significant agricultural and mining sectors
• Both have relatively low population density compared to national averages
• Both have distinct regional identities within their countries

The structure "A is to B as C is to D" tests relational reasoning. Here, the relation is "is a state/province of".
