B. A surplus of agricultural goods

C. A surplus of manufactured goods

D. A surplus of transportation options

Answer: B. A surplus of agricultural goods is necessary for cities to exist, as urban dwellers must obtain their food from rural workers.

A. Agricultural goods

B. Natural resources

C. Manufactured goods or services

19- Which of the following is an example of urban production?

A. Farming

B. Mining

C. Manufacturing

D. Fishing

Answer: C. Manufacturing is an example of urban production, as city dwellers produce goods or services to exchange for food grown by rural workers.

A. Traffic congestion

B. Noise pollution

C. Well-maintained public parks

D. Air pollution from factories

Answer: C. Well-maintained public parks provide a benefit to the community beyond the immediate users of the park, making it an example of a positive externality.

21- Which of the following is a possible solution to address negative externalities from traffic congestion in a city?

A. Implementing a congestion toll

B. Building more highways

C. Providing free parking in the city center

Answer: A. Implementing a congestion toll can help to reduce the negative externalities associated with traffic congestion by internalizing the cost of driving during peak hours.

A. decreased access to job opportunities

B. Self-Reinforcing Effects Generate Extreme Outcomes

C. Externalities Cause Inefficiency

D. Production Is Subject to Economies of Scale

E. Competition Generates Zero Economic Profit

24- Which of the following is an example of an externality in urban economics?

A. The construction of a new housing development

B. The provision of public transportation

C. The pollution generated by a factory
