a. a native american farmer plants a field of corn.
b. a french king pays for a naval voyage to africa.
c. an inca craftsperson prays at a christian church.
d. an italian merchant sells expensive horses in asia.

The correct answer is C. An Inca craftperson praying at a Christian church would only have been possible after the start of the Columbian Exchange.

Explanation:

Columbian Exchange is the process that took place between the 15th and 16th centuries when agricultural products and other foods of the New World (the American continent) were introduced in the Old World (Europe, Africa and Asia) and vice versa. A more extensive definition also includes technological and cultural advances, demography and even diseases.

The term was first used by the American historian Alfred Crosby in 1972 in his book The Columbian Exchange.

As Christianity was a cultural process developed in the Old World, the fact that a member of the Inca society was praying in a Christian church could only have happened after the Columbian Exchange.
