TSA Original Paper 1 · Question 35 · Weakening Arguments
SaveCity planners have proposed converting a central car park into a public green space with trees, gardens, and pedestrian areas. They argue this will improve air quality in the city centre, which currently exceeds safe pollution levels. Studies show that urban trees can absorb significant amounts of nitrogen dioxide and particulate matter. The car park is used by approximately 300 vehicles daily, and removing it will reduce traffic in the immediate area. Similar projects in other cities have created popular community spaces while contributing to pollution reduction. Environmental groups have strongly supported the proposal, citing the urgent need to address air quality in urban areas.
Which one of the following, if true, most weakens the above argument?
