Despite improvements in treatment for asthma, the death rate form 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.
22. 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 sufferers to avoid more beneficial measures.
(E) Ten years ago bronchial inhalers were not available as an asthma treatment.
23. Which one of the following is an assumption on which the argument depends?
(A) Urban pollution has not doubled in the past decade.
(B) Doctors and patients generally ignore the role of allergies in asthma.
(C) Bronchial inhalers are unsafe, even when used according to the recommended instructions.
(D) The use of bronchial inhalers aggravates other diseases that frequently occur among asthma sufferers and that often lead to fatal outcomes even when the asthma itself does not.
(E) Increased urban pollution, improved recording of asthma deaths, and the use of bronchial inhalers are the only possible explanations of the increased death rate due to asthma.
Question Type: Except (Strengthen). Look for AC that doesnt strengthen AC.
Conclusion: Not urban pollution, Not lack of accurate records but inhalers are the cause of increased death.
22) My AC is A.
. Explanation below:
A) Not sure this doesnt strengthen so dont bootout.
B) If records are accurate then it strengthen conclusion [not lack of accurate records] but something else.
C) Inhalers cause lung to be more sensitive. This implies inhaler could be cause for increase death.
D) Not sure. Dont boot out.
E) Strengthen argument. Causal argument.
Between A and D, i boot D out: temporary solutions prevents users from seeking a more benificial/permanent solution. So it could strengthen the argument.
23) My AC is E
. Explanation below:
A) Negate A. Not sure. So dont bootout AC.
B) Negate B. Doctors and patients dont ignore role of allergies. Conclusion inhaler are cause of death still holds true.
C) Negate C. Bronchial inhalers are safe. Conclusion still holds true.
D) Negate D. Bron inhalers dont aggragate other diseases. Conclusion that Inhalers not increased pollution or better records still hold true.
E) Negate E. Inc. urban poll, improv. recording, and bron inhalers ARENT only possible explanations. Then the conclusion doenst hold true.
Negate AC A. Urban pollution has doubled. Still conclusion holds true.
