Based on the picture how might england have used the black legend to motivate and justify its colonization of north america?

This picture would justify English colonization in North America because it portrays the Spanish colonizers as inhumane. In the picture, it states that the Spanish are "Burning a Peruvian to make him tell where the gold is." This picture shows Spanish conquistadores burning an individual alive in order to retrieve information. This was probably seen negatively by many European citizens.

The English used this type of propaganda to their advantage. The English would discuss how the Spanish were colonizing just to hurt Native Americans. However, the English were trying to portrary their mission as one in which they would convert the Native Americans to Christianity using peaceful means.

The answer is  "Two allied nations enforce economic sanctions on a country until its government changes a key policy."

Explanation:

Here we see a foreign policy move coordinated with a partner, none of the two allied nations acts alone in imposing sanctions on the third nation. Among options shown here, this is the best possible example of a multilateral policy.
