GMAT Critical Reasoning (CR) | QOTD: City planner: Our city center will not be adequately

The city planner's conclusion is stated in the last sentence: "The city council must be aggressive in drawing new restaurants, laundries, childcare facilities, and other service industries to the city center; otherwise, the revitalization project will surely fail." How does the city planner arrive at thisconclusion?

• In the first sentence, the city planner essentially asks, "If we only expand residential space in the form of high-priced condominiums, will our city center be adequately revitalized?" The answer, according the city planner, is, "No. Offering expanded residential space in the form of high-priced condominiums is not enough to revitalize the city center."
• So if condominium sales will most likely be insufficient on their own, what else is needed? According to the author, the condominium sales will only sufficiently revitalize the city center if incentives for investment in local small business are also offered. In other words, high-priced condos are not enough; in order revitalize the city center, we need both high-priced condos AND incentives for investment in local small business.
• Restaurants, laundries, childcare facilities, and other service industries are examples of local small businesses. Thus, the author implies that the city council must be aggressive in drawing small businesses to the city center by offering incentives for investment in such businesses.
• If the city council is NOT aggressive in attracting small businesses to the city center, the city center will not be successfully revitalized. The author implies that the revitalization project will only be successful if high-priced condos are offered AND if small businesses are attracted to the city center.
