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 has 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 inhalers 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 inhalers make the lungs more sensitive to irritation by airborne pollen.
(D) By temporarily relieving the symptoms of asthma, inhalers encourage sufferers to avoid more beneficial measures.
(E) Ten years ago bronchial inhalers were not available as an asthma treatment.

我不懂的有两点
1 是答案为什么说a是削弱，populations doubled 与death rates没有关系，跟explanations 1 也没有关系哇
2  E 选项是什么意思？

A) does not support the argument. It might not weaken it, either.

E) simply correlated the increase of the death rate with the arrival of the inhaler, thus a stengthener.
