The answer has to having one spouse because mono- means one and although most of these answer choices talk about only have one blank. Monogamy by definition is the practice or state of being married to one person at a time. Also you can cross the answer choices about believing in one God and believing in a single form of government because the passage or excerpt isn't talking about religion nor government. It talks about being married and a relationship between a man or a woman. (it might have been about a man. I'm not 100% sure whether it's from a guy or girl's point of view)
