Final answer:
The indications of practical benefits such as social security and escaping an unhappy marriage align with instrumental reasons for staying single or remarrying.
Step-by-step explanation:
The paragraph hints at instrumental reasons for staying single or getting remarried, such as social security and the escape from an unhappy marriage. Instrumental reasons pertain to the practical benefits or utilities such as financial security or personal safety that can be derived from being single or making choices regarding remarriage. This contrast with emotional or normative reasons, which would relate more to feelings, love, and cultural expectations, respectively.
Moreover, when we consider the given options, it stands to reason that the benefits such as social security and escaping an unhappy marriage, which are practical and utilitarian in nature, align with instrumental reasons.
