This question tests your ability to strengthen an argument by identifying evidence that supports the conclusion. Strengthening an argument involves providing information that makes the conclusion more likely to be true given the premises. The argument concludes that switching to compostable cutlery caused the reduction in landfill waste and recommends expansion, based on the observed decrease after the change. A vulnerability is that other factors, like concurrent campaigns or inconsistent implementation, might have contributed to the reduction instead. Choice B strengthens the argument by linking consistent compliance with compostable cutlery to larger waste reductions, supporting causation. In contrast, choice A is a distractor that introduces an alternative cause, such as the reusable bottle campaign, which could explain the reduction independently. Choice C is irrelevant, as cost differences do not address the causal impact on waste reduction.

This question tests your ability to strengthen an argument by identifying evidence that supports the conclusion. Strengthening an argument involves providing information that makes the conclusion more likely to be true given the premises. The argument concludes that installing protected bike lanes on the remaining major corridors will reduce bicycle-car collisions citywide, based on a decline in collisions on three specific corridors after installation. A vulnerability is that the three corridors may not be representative of the city as a whole, or other factors might have influenced the decline, making generalization uncertain. Choice E strengthens the argument by providing evidence from comparable cities where widespread installation led to citywide reductions, even with constant traffic, supporting the causal link and broader applicability. In contrast, choice B is a distractor that weakens the argument by suggesting the corridors were selected for high collision rates, making them unrepresentative. Choice D is irrelevant, as resident support for infrastructure does not address collision reduction effectiveness.

This question tests your ability to strengthen an argument by identifying evidence that supports the conclusion. Strengthening an argument involves providing information that makes the conclusion more likely to be true given the premises. The argument concludes that planting trees throughout the city will reduce overall summer heat, based on lower temperatures on downtown streets with new trees. A vulnerability is that the downtown results may not generalize citywide, or other changes could have contributed to the cooling. Choice D strengthens the argument by providing evidence from similar cities where widespread tree planting led to citywide temperature reductions, supporting broader efficacy. In contrast, choice C is a distractor that introduces an alternative cause, like lighter paving, which could explain the cooling independently. Choice A is irrelevant, as pedestrian traffic does not address heat reduction causation.

This question tests your ability to strengthen an argument by identifying evidence that supports the conclusion. Strengthening an argument involves providing information that makes the conclusion more likely to be true given the premises. The argument concludes that the scheduling feature increases engagement and recommends making it mandatory, based on more lessons completed after launch. A vulnerability is that new content or marketing might have driven increases, not the feature. Choice B strengthens the argument by showing greater increases among feature users, linking it to engagement. In contrast, choice C is a distractor that introduces an alternative cause, like new content. Choice A is irrelevant, as preferences do not address engagement causation.

This question tests your ability to strengthen an argument by identifying evidence that supports the conclusion. Strengthening an argument involves providing information that makes the conclusion more likely to be true given the premises. The argument concludes that the tax credit caused the decline in vacant storefronts and recommends increasing it, based on fewer vacancies after offering. A vulnerability is that rent reductions or other factors might have filled storefronts, not the credit. Choice B strengthens the argument by showing most filled storefronts used the credit, linking it to the decline. In contrast, choice A is a distractor that introduces an alternative cause, like lower rents. Choice C is irrelevant, as restaurant counts do not address vacancy causation.

This question tests your ability to strengthen an argument by identifying evidence that supports the conclusion. Strengthening an argument involves providing information that makes the conclusion more likely to be true given the premises. The argument concludes that quarterly check-ins reduce turnover and recommends further investment, based on lower turnover after replacement. A vulnerability is that salary changes or varying implementation might explain the drop, not check-ins. Choice C strengthens the argument by linking consistent check-ins to larger turnover decreases, supporting causation. In contrast, choice A is a distractor that introduces an alternative cause, like salary increases. Choice E is irrelevant, as industry comparisons do not address internal causation.

This question tests your ability to strengthen an argument by identifying evidence that supports the conclusion. Strengthening an argument involves providing information that makes the conclusion more likely to be true given the premises. The argument concludes that free Friday evenings caused increased shop revenue and recommends extending to Saturdays, based on revenue rise after implementation. A vulnerability is that new merchandise or reviews might have driven revenue, not free admission. Choice B strengthens the argument by showing similar spending per visitor on free evenings, suggesting increased visitors from free admission boosted revenue. In contrast, choice A is a distractor that introduces an alternative cause, like new merchandise, which could explain the increase. Choice E is irrelevant, as attendance comparisons do not address revenue causation.

This question tests your ability to strengthen an argument by identifying evidence that supports the conclusion. Strengthening an argument involves providing information that makes the conclusion more likely to be true given the premises. The argument concludes that the compound reduced pipe corrosion and recommends continuation, based on fewer discolored water complaints after addition. A vulnerability is that staffing or weather might have affected complaints, not corrosion reduction. Choice B strengthens the argument by providing lab evidence of lower corrosion rates, directly supporting the causal link. In contrast, choice C is a distractor that introduces an alternative cause, like more staff handling complaints. Choice A is irrelevant, as taste complaints do not address discoloration causation.

This question tests your ability to strengthen an argument by identifying evidence that supports the conclusion. Strengthening an argument involves providing information that makes the conclusion more likely to be true given the premises. The argument concludes that text reminders reduce no-shows and recommends network-wide implementation, based on a rate drop after starting reminders. A vulnerability is that opt-outs or other changes might bias results, not reflecting true causation. Choice C strengthens the argument by showing lower no-shows among reminder recipients versus opt-outs, directly linking reminders to reductions. In contrast, choice B is a distractor that introduces an alternative cause, like shorter appointments, which could explain the drop. Choice A is irrelevant, as texting plans do not address reminder effectiveness.

This question tests your ability to strengthen an argument by identifying evidence that supports the conclusion. Strengthening an argument involves providing information that makes the conclusion more likely to be true given the premises. The argument concludes that requiring the filtration system at similar factories will reduce regional particulate pollution, based on a decline near one factory after installation. A vulnerability is that weather changes or other measures could have caused the decline, not the system. Choice B strengthens the argument by ruling out weather and other interventions, isolating the system's effect. In contrast, choice C is a distractor that is off-target, as other pollution sources do not address the system's impact on factory emissions. Choice A is irrelevant, as installation costs do not bolster pollution reduction claims.
