Practice Question
Question No.: 36
Page: 129
Difficulty:

Certain messenger molecules fight damage to the lungs from noxious air by telling the muscle cells encircling the lungs’ airways to contract. This partially seals off the lungs. An asthma attack occurs when the messenger molecules are activated unnecessarily, in response to harmless things like pollen or household dust.

Which of the following, if true, points to the most serious flaw of a plan to develop a medication that would prevent asthma attacks by blocking receipt of any messages sent by the messenger molecules referred to above?

(A) Researchers do not yet know how the body produces the messenger molecules that trigger asthma attacks.
(B) Researchers do not yet know what makes one person’s messenger molecules more easily activated than another’s.
(C) Such a medication would not become available for several years, because of long lead times in both development and manufacture.
(D) Such a medication would be unable to distinguish between messages triggered by pollen and household dust and messages triggered by noxious air.
(E) Such a medication would be a preventative only and would be unable to alleviate an asthma attack once it had started

+1 D

Clearly if we the new medication blocks the receipt of ANY messages sent by the messenger molecules, it might not be able to differentiate between what is harmful and harmless. This is the flaw in the plan and has been mentioned correctly in option D.

Which of the following, if true, points to the most serious flaw of a plan to develop a medication that would prevent asthma attacks by blocking receipt of any messages sent by the messenger molecules referred to above

There is no conclusion in the stimulus...it is all premises. The "conclusion" in any plan of action is the objective of the plan, and the "premises" are the steps of the plan. In this case, the conclusion would be to develop a medication that prevents asthma attacks, and the premises are the statements in the stimulus and that the medication would prevent the receipt of messages sent by the messenger molecules.

Answer choice A is out of scope. Knowing how the messages are formed is not relevant. We are only interested in them being transmitted or blocked.

Answer choice B is also out of scope. We are comparing messages being sent by messenger molecules in general, and not differences amongst people.

Answer choice C is irrelevant. Having some lead time does not make the plan flawed.

Answer choice D correctly indicates a potential problem: while perhaps it would prevent asthma attacks from relatively harmless molecules like dust, it could also result in serious injury by allowing for intake of harmful air. This is a flaw in a plan that is designed to help people.

Answer choice E is out of scope. We are talking about preventing asthma attacks, not stopping them once they have started.

I hope this helps!!!

Exactly!
The argument put forth (to develop a medication that would prevent asthma attacks by blocking receipt of any messages sent by the messenger molecules) disregards any potential disadvantage or side effects of doing so.
The biggest assumption here is that following the suggestion will have no negative consequences.
Option D introduces a potential negative consequence and thus weakens the argument.

Hope that helps,
Ajeeth

It seems like D to me as well. Without knowing the source of activation of messenger molecules the medication can block messages in case of noxious air causing damage to lungs.

THE PLAN CAN ONLY FAIL IF ----THOUGH IT DOES STOP ASTHMATIC ATTACK, BUT INHIBITS THE FUNCTIONING OF THE NOXIOUS AIR COUNTER MECHANISM OF THE HUMAN BODY....
SURE WE HAVE ELIMINATED THE DRAW BACK --- BUT AT THE EXPENSE OF ELIMINATING THE VERY EXISTENCE OF THE - COUNTER NOXIOUS AIR POISONING MECHANISM ITSELF....... ANSWER "D"................

Type - Flaw
Boil it down - Plan to develop asthama medication that would prevent asthma attacks by blocking receipt of any messages sent by the messenger molecules
Pre-Thkining - What if the medication will also block receipt of any messages sent during the case of noxious air ?

(D) Such a medication would be unable to distinguish between messages triggered by pollen and household dust and messages triggered by noxious air. Correct answer

If message is blocked one of it's positive effects will also be blocked. Hence D is the correct choice.

Premise: The plan is to develop a medication that would prevent asthma attacks by blocking receipt of any messages sent by the messenger molecules.

Pre-thinking:
This is absurd because you don't want all the messages to the messenger molecules to be blocked. You only want the harmless messages to be blocked. For example, if there is carbon monoxide in the vicinity, then I want the messenger molecules to get activated and protect my lungs so that my life can be saved.

So the flaw in the plan is that it is preventing all messages from reaching the messenger molecules. D says the same thing in different words.
