Despite improvements in treatment for asthma, the death rate from this disease has doubled during the past decade from its previous rate. Two possible explanations for this increase have been offered. First, the recording of deaths due to asthma has become more widespread and accurate in the past decade than it had been previously. Second, there had been an increase in urban pollution. However, since the rate of deaths due to asthma has increased dramatically even in cities with long-standing, comprehensive medical records and with little or no urban pollution, one must instead conclude that the cause of increased deaths is the use of bronchial inhaler by asthma sufferers to relieve their symptoms.
Each of the following, if true, provides support to the argument EXCEPT”
(A) Urban populations have doubled in the past decade.
(B) Records of asthma deaths are as accurate for the past twenty years as for the past ten years.
(C) Evidence suggests that bronchial inhalers make the lungs more sensitive to irritation by airborne pollen.
(D) By temporarily relieving the symptoms of asthma, inhalers encourage suffers to avoid more beneficial measures.
(E) The years ago bronchial inhalers were not available as an asthma treatment.
A is the correct answer.
Why A can't support the argument.
According to A, the populations have doubled in the past decade, if the number of people die from using of inhaler is 4 times the figure before, then the conclusoin of the passage still stand. (the death rate form asthma has doubled during the past decade from its previous rate.)
I can't figure out where am I wrong. thank you responding!!!
