The purpose of a marriage during the medieval period is best characterized by which of the following?

it let those in love spend their lives together. religion required it for salvation. it was a means for people to procreate and expand the population. it increased a family's power or wealth.

All of these answers were seemingly correct in my book but I did a little research. Marriage back then was not based on love; most marriages were political arrangements. Husbands and wives were generally strangers until they first met. If love was involved at all, it came after the couple had been married. Even if love did not develop through marriage, the couple generally developed a friendship of some sort. Also, the arrangement of the marriage was based on monetary worth. Which means that the amount of money a girls family possessed will affect the one whom she will be married off to. So your answer is D, to increase a family's power or wealth.

The answer is crop yield.
