01 If a coastal city loses sea trade but develops tourism, which conclusion about population distribution is reasonable?
Answer and explanation
Correct answer: B. The decline of one economic function may be partly offset by another.
Explanation: B is correct. Losing sea trade may reduce some port-related jobs, but tourism can create work in hotels, restaurants, transport, and other services. These opportunities may help retain residents or attract new ones, although they do not guarantee that the city’s population will grow.
