skad [1K]

Answer:

Yali´s question: "Why you white man have so much cargo and we New Guineans have so little?"

Explanation:

This question from Yali, a Papua New Guinean political leader, led Diamond to develop his research published as Guns, Germs, and Steel (1997).

The question refers to the word cargo as New Guineans use it, meaning the goods brought by Westerners, which were considered as proof of the white man’s strength.

Yali’s question is actually about the roots of inequality.
