Transportation planning shapes urban life most directly through accessibility—the ease with which people can reach jobs, education, healthcare, services, and social activities. When transit networks, walking and biking paths, and station locations are designed to connect neighborhoods to opportunities, people from diverse backgrounds can participate in labor markets and community life, which promotes integration. If planning prioritizes expanding reliable transit and safe connections in underserved areas, segregation can be reduced because access to opportunities becomes more evenly distributed. On the other hand, gaps in transportation access can reinforce segregation by limiting where people can work or access essential services. While air quality, housing prices, and economic growth are also affected by transport, the core influence of transportation planning is on who can reach what, i.e., accessibility and the potential for social integration.

Free trade opens markets and invites more players into competition. That greater competitive pressure forces firms to cut costs, improve quality, and innovate, which pushes resources toward their most productive uses and tends to raise overall efficiency. It doesn’t eliminate every inefficiency—there can be adjustment costs and lingering distortions—but the main effect is to boost competition and potential efficiency gains. It also doesn’t guarantee government price controls; instead, free trade often reduces reliance on such interventions while governments may still regulate in other ways.

The key idea tested here is how welfare programs blend federal standards with state control. SNAP is funded by the federal government and the federal agency sets the rules, benefits, and eligibility framework, but states run the program day to day—processing applications, determining eligibility within those rules, and distributing benefits to recipients. So funding comes from the top, but administration and implementation happen at the state level. TANF works differently: it’s a block grant from the federal government to states, giving states a fixed pool of funds to use as they see fit within broad federal requirements. States decide how to design their welfare-to-work programs, set eligibility within those federal guidelines, and administer the benefits, with the federal government providing the money and the overarching rules. So the statement aligns with this structure: SNAP is federally funded but state-administered; TANF is a federal block grant to states with discretion.

Understanding how social policy is categorized helps here. Medicare is a social policy program—the health insurance program for many seniors and disabled people, financed by payroll taxes and premiums. Contributory programs are the social insurance side, funded by workers’ contributions. Noncontributory programs are means-tested aid financed by general revenues. The tax expenditure system, however, isn’t a category of social policy itself; it’s a financing mechanism that uses the tax code—through deductions, exclusions, and credits—to subsidize policy goals without direct spending. It supports social objectives, but it isn’t a stand-alone policy category, which is why this item identifies it as not belonging to the policy categories.
