WeakenDiff: Hardest
Logic Breakdown
Passage Summary: Just like fixing your car before it breaks is smart, the city council is smart for hiring an economic adviser, especially since other cities that planned ahead made a lot of money.
Conclusion: The city council deserves praise for hiring a long-term economic development adviser.
Reasoning: Hiring an adviser is a wise investment similar to preventive car maintenance, and other cities that planned for development saw big returns.
Analysis: The columnist relies on an analogy between car maintenance and hiring a consultant, but analogies are only as strong as the similarities between the two things being compared. If hiring an adviser doesn't actually function like 'maintenance'—perhaps because the adviser's suggestions are rarely followed or the cost outweighs the benefit—the argument falls apart. Additionally, the evidence about 'other cities' is vague; we don't know if those cities specifically hired *advisers* or if they did something else entirely. Look for an answer that drives a wedge between the act of hiring this adviser and the guaranteed 'payoff' the author expects.

Unlock Full Passage15.Which one of the following, if true, most weakens the columnist's argument?
Correct Answer
B
By highlighting that this city’s population and economy are much smaller than those of the comparison cities at the time they invested, it undercuts the comparability premise. Returns on economic development planning often depend on scale; this makes the cited evidence a weak predictor for this city, weakening the argument.
