The key idea here is how Conservative policy in the 1980s–1990s framed the family and welfare. The approach emphasized the nuclear family as the main source of support and aimed to reduce welfare dependence by encouraging self-help and personal responsibility. Policies during this period pushed people to work, limited welfare provision, and promoted individual and family responsibility over state provision. That makes the statement about strengthening nuclear families through self-help and reduced reliance on welfare the best fit, because it directly reflects the era’s emphasis on the family as the core unit of support and on cutting welfare reliance. The other options describe approaches—expanding welfare, relying on extended families, or universal basic income—that aren’t aligned with the Conservative stance of that time.
