Answer:
Exogamous marriage
Explanation:
Cate is the daughter of a Senator and the former CEO of a Fortune 500 company. Harry grew up on a farm, tilling the land for a living. They are planning a June wedding. They will have an exogamous marriage. Exogamy is not marrying someone of your own group. Exogamy has two aspects. The biological aspect is marrying a non-blood related individual. Cultural exogamy is marrying outside the group of belonging. Cate is marrying outside her social group and so is doing Harry.
