Every year many people become ill because of airborne mold spores in their homes. After someone becomes ill, specialists are often hired to eradicate the mold. These specialists look in damp areas of the house, since mold is almost always found in places where there is substantial moisture. If one wishes to avoid mold poisoning, then, one should make sure to keep all internal plumbing in good condition to prevent leakage that could serve as a breeding ground for mold.

Which of the following is an assumption on which the argument depends?


A. Mold cannot grow in dry areas.
B. Most homeowners know enough about plumbing to determine whether theirs is in good condition.
C. Mold itself does not create moisture.
D. No varieties of mold are harmless.
E. Mold spores cannot be filtered from the air.

C has to be the answer.

A cannot be the answer because it is clearly stated in the passage that "mold is almost always found in places where there is substantial moisture " , so choice A (Mold cannot grow in dry areas) is not an assumption but a fact .

I THOUGHT IT WAS B BUT B IS MORE RELATED TO THE CONCLUSION THAN TO THE ARGUMENT.

Here's my take, someone please feel free to correct me if I am incorrect in any of my thinking: Hopefully some of you will get a better idea of why the INCORRECT answers are wrong.

D and E are both outside of the scope of the argument. D is dealing with a variety of mold, which in the passage you see no mention of. E involves filtering spores from the air, which is again not mentioned in the argument

Now with A:
"Mold can grow in dry areas", if you take the contrapositive of this statement you are left with "Mold can not grow in dry areas". If you were to use the contrapositive to attack the argument, would the argument crumble, no.

Why, because the argument states "since mold is almost always found in places where there is substantial moisture." Almost always does not count for always (100%).

With B:
The argument states "one should make sure to keep all internal plumbing in good condition to prevent leakage that could serve as a breeding ground for mold.

While the possible answer B states "most homeowners know enough about plumbing to determine whether theirs is in good condition"

Difference : The argument uses "internal plumbing" while the possible answer of B usues "plumbing"... need to be careful with reading.

Left with the answer C:
Mold itslef does not create moisture
->by taking the contrapositive of this your left with "mold itself DOES create moisture". This is where you are able to break the argument and make it crumble.

Argument assumes that "mold is almost always found in places where there is substantial moisutre". Assumes moisutre is the effect of the mold. But if mold is the effect of the moisutre it makes the argument crumble.

Last statement in the argument : "one should make sure to keep all internal plumbing in good condition to prevent leakage that could serve as a breeding ground for mold."

This assumes B - Most homeowners know enough about plumbing to determine whether theirs is in good condition.

is that correct?

CR in my words : Molds cause problem. Expert come and eradicate it. They look in moist places. So, to avoid mold, avoid moist places.
Assumption : Molds form in moist places

Quote:

Mold cannot grow in dry areas.

No varieties of mold are harmless.

Mold spores cannot be filtered from the air.

Answer = A. Because if mold themselves create moisture, then conclusion fails.
B - Third party - Eliminate. This is wrong because it is not necessary that they themselves know. They can ask others experts to ensure plumbing is in good condition.
C - Eliminate - This is not assumption, this is conclusion.... Tricky though.....
D - Third party - Eliminate
E - Out of scope - Eliminate
Answer A.

Re: CR-Mold [#permalink] New post 16 May 2008, 09:12
First of all you need to get to the conclusion of the sentence before answering the question.

Fact/Premise: Every year many people become ill because of airborne mold spores in their homes.
Fact/Premise: After someone becomes ill, specialists are often hired to eradicate the mold. Fact/Premise: These specialists look in damp areas of the house,
Fact/Premise: : since mold is almost always found in places where there is substantial moisture.
Conclusion: If one wishes to avoid mold poisoning, then, one should make sure to keep all internal plumbing in good condition to prevent leakage that could serve as a breeding ground for mold.

Now there is an assumption which is not implied in this passage is "Mold are found in damp places and faulty plumbing is reason for that". What if there is some other reason for damp, specially what if Mold can create damp areas.

A: Mold itself does not create moisture.
Exactly attacking the assumption.

B: Most homeowners know enough about plumbing to determine whether theirs is in good condition.
Even if homeowners does not know plumbing they can take proactive help from professionals.

C: Mold cannot grow in dry areas.
Passage is concerned about where mold lives and not about how mold grows.

D: No varieties of mold are harmless.
Harmless or harmful this has no relevance at all.

E: Mold spores cannot be filtered from the air.
Even if they can be filtered but that does not attack the conclusion.

I will go with A.

That is the crux of CR. You have to insure whether or not conclusion is present in passage or not. In case it is present you can be asked following types of questions:
Strengthen, Weaken, Assumption etc.

However if conclusion is not present, then you can be asked:
what is conclusion, inference, etc.

remember guys, in am assumption question, if reversing an answer choice, destroys the conclusion, its the correct assumption.

so in this question if u are stuck between A and B, lets reverse them.

A) Mould causes moisture. This means that looking after plumbing won't make a difference and destroys the conclusion. So the original answer choice should be a correct assumption.

B) Owners do not know how to diagnose plumbing problems. This does not destroy the conclusion, since the conclusion states that "one must make sure that plumbing is in good order", which can be done by hiring a plumber, right?

so the answer must be A

Which of the following is an assumption on which the argument depends?

A. Mold itself does not create moisture. ->irrelevant
B. Most homeowners know enough about plumbing to determine whether theirs is in good condition. ->not fully convincing
C. Mold cannot grow in dry areas. -> perfect.Negate this argument .The argument falls apart.The purpose of the argument is how to remove moisture.That itself falls apart when we say mold can grow in dry places.
D. No varieties of mold are harmless. ->I dont see any link
E. Mold spores cannot be filtered from the air. -> irrelevant.


I go for (C).OA plsss?

I'd pick A.

Quote:

If one wishes to avoid mold poisoning, then, one should make sure to keep all internal plumbing in good condition to prevent leakage that could serve as a breeding ground for mold.

Which of the following is an assumption on which the argument depends?


Argument says that ‘to prevent leakage’ is necessary condition for ‘avoiding mold poisoning’ (note that it says nothing whether it is sufficient). So we need assumption that confirms that ‘preventing leakage’ is indeed necessary.


A. Mold itself does not create moisture. (here it is. If mold created moisture by itself, then clearly preventing leakage would be pointless, and thus won’t be necessary to avoid poisoning)

B. Most homeowners know enough about plumbing to determine whether theirs is in good condition. (how much they really know about plumbing is irrelevant to conclusion)

C. Mold cannot grow in dry areas. (the argument does not assume that. The conclusion would still be true if mold could grow in dry areas as well. Perhaps it grows there, but at slower rate or in lesser amount that in moist places. So preventing leakage still makes sense.)

D. No varieties of mold are harmless. (the argument does not assume that. There might be harmless ones as weel as dangerous)

E. Mold spores cannot be filtered from the air. (the argument does not assume that. Even if mold can be filtered from air, the moist places could still hold danger)

Premise: Since mold is almost always found in places where there is substantial moisture
Conclusion: If one wishes to avoid mold poisoning, then, one should make sure to keep all internal plumbing in good condition to prevent leakage that could serve as a breeding ground for mold.
The argument assumption either supports the conclusion or validates the premise.

A. Mold itself does not create moisture. [Hold it]
B. Most homeowners know enough about plumbing to determine whether theirs is in good condition. [What most homeowners know – irrelevant]
C. Mold cannot grow in dry areas.[this contradicts the argument – eliminate it]
D. No varieties of mold are harmless. [varieties of mold not discussed– eliminate it]
E. Mold spores cannot be filtered from the air. [Mold spores alterations out of scope– eliminate it]

Answer: A

A for me too. The reason why C is wrong because the argument's logic is causal. The correct answer must address the causal relationship. Option C doesn't address this causal relationship. Here's why:

C. Mold cannot grow in dry areas


My explanation: Even if Mold can grow in dry areas, the argument is claiming that if you avoid leakage, then you will avoid mold poisoning. So where is this causal relationship in option C? In option A, however, it says that "Mold itself does not create moisture." This option directly addresses the causal relationship, and so this is our answer.

Hope this helps!
