Question 3 of 15
Statement
Several large cities have experienced a rise in respiratory illnesses over the past five years. Health officials believe this may be linked to the increasing number of diesel vehicles on the road. A recent study showed that diesel emissions contain fine particles that can penetrate deep into the lungs, aggravating asthma and other respiratory issues. In response, City A introduced new regulations restricting diesel vehicles in high-traffic areas. After one year, City A reported a 12% drop in hospital admissions for respiratory problems.
Inference:
The diesel vehicle restrictions in City A may have contributed to improved air quality in high-traffic areas.
