Which term describes a couple living together in a committed romantic relationship without formal marriage?

• A. Linked Lives
• B. Cohabitation
• C. Organ Reserve
• D. Choice Overload

Answer: (B)

Understanding how intimate partners organize their living arrangements when not married. Cohabitation describes a couple living together in a committed romantic relationship without formal marriage. This term specifically captures the scenario of sharing a home and a partnership without entering into marriage, which is exactly what the item is describing. Linked lives refers to how people’s life paths and outcomes influence one another within families over time, a broader social concept rather than a living arrangement. Organ reserve is a biological term about the body's capacity to respond to stress and aging, not related to relationship status. Choice overload describes a cognitive phenomenon where too many options hinder decision-making, again unrelated to how couples structure their relationship. So the best fit for a couple living together in a committed relationship without formal marriage is cohabitation.
