hii carcass i have doubt in the following question
A bullet train travels in excess of 150 miles per hour. Therefore, if a train travels slower than 150 miles per hour, it is not a bullet train.
Which of the following most closely parallels the reasoning used in the argument above?
A) An orange ripens only on the vine. If it ripens on the vine, then it is not an orange.
B) Newspapers are often read by more than one person. Therefore, magazines are also likely to be read by more than one person.
C) An earthquake of 5.0 or above on the Richter scale causes massive damage. If there is not massive damage, then the earthquake did not attain a 5.0 or above.
D) A supersonic plane travels at speeds in excess of Mach 1. If it is not supersonic, then it will travel at speeds below Mach 1.
E) Fluoride generally prevents cavities. If there are no cavities, then there was no fluoride used.

its explaination is as follows:
C
To answer this parallel-the-reasoning question, you have to break down the original argument, and then find an answer choice that mimics it exactly. In this case, the argument says a bullet train travels in excess of 150 miles per hour (if A, then B). Therefore, if a train travels less than 150 miles per hour, then it is not a bullet train (if not B, then not A). Now all you have to do is find an answer choice that mimics that reasoning exactly. Choice A, broken down, reads, “if A, then B … so if B, then not A.” This isn’t it. Eliminate it. Choice B breaks down to “if A, then B … therefore C will also cause B.” That’s not it either. Choice C breaks down to “if A, then B … therefore if not B, then not A.” This is the best answer. Choice D might seem tempting because it also has to do with a fast means of transportation, but what counts here is the reasoning: if A, then B … if not A, then not B. This is close, but no cigar. Choice E is also appealing; you may even think it mimics the argument exactly. But there’s a trick. The first half of the sentence reads, “Fluoride generally prevents cavities” (if A then B). Note that the B part is about the prevention—not the presence—of cavities. So the second half, “If there are no cavities, there was no fluoride,” actually breaks down to “if B, then not A.”


doubt- i think in e also if a(flouride) then b(cavities) and if not b(not cavities) then not a(not flouride) is valid...so it is creating confusion in my mind..please help me :(

I admit my set is a bit tough and it should have done in the last stage of your preparation.

The key here is to stay really focus on, there is nothing in there to be confused dude :)

E) Fluoride generally prevents cavities. If there are no cavities, then there was no fluoride used.

If NO cavities, then fluorid IS present

If YES cavities, NO flouride.....so we have NO/YES or YES/NO

back to our question we have : YES bullet YES > 150 or NO 150 - NO Bullet ...so we have YES/YES or NO/NO do you see the difference ???

We have no a mix up of YES and NO but a reasoning in which we have a YES / YES coupled or NO /NO

In C we have just this so is the correct answer.

I hope is clear now to you :)

Hey Carcass ,
thanks a lot ... very useful collection.

Need help on Q5. Answer choice C and D.... please elaborate.

A bullet train travels in excess of 150 miles per hour. Therefore, if a train travels slower than 150 miles per hour, it is not a bullet train.
Which of the following most closely parallels the reasoning used in the argument above?
A) An orange ripens only on the vine. If it ripens on the vine, then it is not an orange.
B) Newspapers are often read by more than one person. Therefore, magazines are also likely to be read by more than one person.
C) An earthquake of 5.0 or above on the Richter scale causes massive damage. If there is not massive damage, then the earthquake did not attain a 5.0 or above.
D) A supersonic plane travels at speeds in excess of Mach 1. If it is not supersonic, then it will travel at speeds below Mach 1.
E) Fluoride generally prevents cavities. If there are no cavities, then there was no fluoride used.

Glad to help you.

The reasoning is this: if A, then B; therefore if not B, then not A.

D instead is if A, then B; if not A, then not B

Notice the difference. In D you should have if it travel at speeds below Mack 1, the it is not supersonic plane, and not the other way around.

So C is the answer

Thanks a lot Carcass.
It helps .
Can you please refer some more useful link/collection of similar questions dealing with "the type of reasoning/parallel reasoning"....I'm making mistake in identifying the pattern...few more questions would help.

I have tried to perform a research by tags but nothing came up with CR question with similar reasoning or mimic the argument

They are a minor question type. Try on your own but you should concentrate your study on major question type. weaken, strenghten, assumption and inference.

So do not be so concern about this :wink:

In the second question, the correct answer choice is D.
Smaller class sizes and capital improvements in a school system tend to increase property values in the surrounding community.
Why not option A, which could also be true since its not explicitly mentioned about the increase in the property value.
Can anyone help me with this question.


Read the question,

"Which of the following, if true, provides the town council with the strongest counter to the objection that its plan is unfair?"

Now, go back and look at question 1. Why was it declared unfair?

"....because the majority of the people who would end up paying for the improvements receive no benefit from them."

Consequently, we can conclude that option A would certainly do nothing to alleviate this concern. While it may address the issue of 'fairness', it is not directly dealing with the type of fairness outlined in the objection of question 1. Has to be D.




But how do we know that the surrounding community consists of houses which are valued over $500000 and whose owners will benefit from the property appreciation? It is possible that these houses are not in the surrounding community but they are paying the mentioned tax

Ok :)

Trying to analyze the questions. First one the sixth

Quote:
A recent report determined that although only eight percent of drivers entering Banff National Park possessed yearly entry permits, as opposed to day passes, these drivers represented fifteen percent of all vehicles entering the Park. Clearly, drivers who possess yearly entry permits are more likely to enter Banff National Park on a regular basis than are drivers who do not.

The conclusion drawn above depends on which of the following assumptions?

A) The number of entries to Banff National Park by drivers with yearly entry permits does not exceed the number of yearly entry permits issued by the Park.

B) Drivers who possess yearly entry permits to Banff National Park are more likely to stay longer in the Park than drivers who do not.

C) All drivers with yearly entry permits to Banff National Park entered the Park at least once during the period of the report.

D) Drivers possessing yearly entry permits to Banff National Park are more likely to enter the Park regularly than are drivers who do not.

E) Drivers who entered Banff National Park with yearly permits during the period of the report were representative of the types of drivers who have entered other national parks with similar yearly permits.


From a logic standing point we do know that 8% of those who enter the parlk have a yearly pass and that at the same time they are 50% of all entries. So from this we can infer that in proportion the are the majority of all entries. 8 people out of 16 have a yearly pass VS 8 people who could have a daily, weekly, monthly, semestral pass...we do not know. So the logic here leads me to think what: 8 people enter to visit the park on a regaular basis, more than what the other 8 people do. So, they have an entry at least once

The other options are not rerlated to this logic and to our argument conclusion. Now I hope is more clear. Aside the various strategy you can use to solve asusmption question, one among the others is always effective: must be true for the conslusion of the argument.



Hope is clear


Hi Carcass,
First of all thanks for this great collection. It has a lot of great questions. I have a problem with the explanation for #6 because your explanation says 50% while the question says 15%. So 8% entering 15% does not necessarily mean that they are entering more often than 85% of day pass people. If for instance, C is correct which means that 8% of yearly permit people actually represents 1% of the total yearly pass holders than the arguments that yearly permit people go more often falls apart.

This is why I think C is a better answer especially considering it says 15% not 50%. If its 50% then yes D seems like the logical answer BUT D simply repeats the last sentence of the prompt and ASSUMPTIONS are implied and are not supposed to be explicitly stated in the prompt. Unless the source is OG i'd be very suspect of this OA.

carcass Please ensure me the difficulty level of the ques. bank. In comments, one wrote ''All the questions are above 650 level.'' But you mentioned that difficulty level is sub-600. I am confused

Maybe, you were misled by the tags I used: sub-600 but is only a tag, I could not put more, I wanted to specify also the CR question types.

That said, yes they are from different levels of difficulty. No worries.

Moreover, you have also this one bank https://gmatclub.com/forum/critical-rea ... 12197.html
