Official Solution:
City planner: Our city center will not be adequately revitalized simply by expanding residential space in the form of high-priced condominiums. The condominium sales will most likely be insufficient unless incentives for investment in local small business are offered. 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.
Which of the following, if true, most weakens the reasoning in the argument above?
A. When several nearby cities recently attempted to revitalize their city centers by expanding luxury residential space, small businesses rushed to take advantage of the new market, significantly contributing to the success of the revitalization projects.
B. In a statewide survey of buyers and potential buyers of luxury condominiums, the majority of respondents indicated that they do not consider proximity to service industries to be the most important factor when choosing a residence.
C. The city council's recent attempt to attract new restaurants to the city center was largely unsuccessful.
D. An increase in luxury condos would substantially increase property tax revenue in the city center.
E. Before small businesses could open near the proposed luxury condominiums, significant investment would be needed to rebuild the infrastructure and retail spaces in the area.
Conclusion (what must be shown): “The city council must be aggressive in drawing new service-industry small businesses to the center; otherwise, the revitalization will fail.”
Reasoning chain:
- Adding luxury condominiums alone is unlikely to be sufficient.
- Sales will reach the needed level only if small-business incentives are offered.
Key assumption: Small businesses will not move in spontaneously once luxury condos appear; they require council incentives. Knock out this assumption and the prescription collapses.
Evaluate the choices (seek the statement that most undermines the assumption):
(A) Nearby cities added luxury condos and businesses rushed in unprompted, leading to successful revitalizations.
This directly contradicts the assumption that incentives are needed. If the same dynamic could occur here, the council’s “aggressive” action is unnecessary. Strongly weakens → Correct.
(B) Luxury-condo buyers say proximity to services is not their top concern.
This mildly weakens (suggests sales might succeed even without businesses), but it does not show that businesses will show up by themselves. Impact is limited—less than (A).
(C) A recent (apparently timid) attempt to lure restaurants failed.
Implies stronger action is needed, bolstering the planner. Strengthens / irrelevant.
(D) Higher property-tax revenue from condos alone.
Financial upside does not touch the need-for-businesses link. Irrelevant.
(E) Large infrastructure investments would precede small-business openings.
Makes it harder for businesses to arrive unaided, reinforcing the planner’s stance. Strengthens.
