Hi VeritasKarishma


https://gmatclub.com/forum/an-automotiv ... l#p2196110


IN this question:
why is option E incorrect?
If the sport cars involved in warranty claims require another warranty claim, can't we say it strengthens the conclusion that SC are more susceptible to manufacturing defects than LT.


Also would the following Assumption be a valid one:

Passage : nearly three times as many warranty claims were performed on sport-utility vehicles than were performed on light trucks.

We are only talking about claims that were performed and then we are concluding about manufacturing defect susceptibility.

What if the manufacturing defects in light trucks are not reported for claims as they cheaper to repair or the claims lead to loss of their final bonus.

So assumption: The manufacturing defect damage in light trucks does not cause any loss when reported for warranty claims.


A. Warranty claims on sport-utility vehicles are, on average, more expensive to perform than are those on light trucks.
This was slightly on the lines of my Pre-Thinking.
But I eliminated this option because we don't whether light trucks are very cheap or just cheaper in relation to light trucks.
Am I correct in my reasoning for this option elimination.


Looking forward to your reply.

Hello VeritasKarishma
Thank you for all these initiatives for helping us out. I wanted your assistance in evaluate questions. My current approach to Evaluate question is that the correct choice when true would strengthen and when not true would weaken the argument. But I have encountered questions in which the correct choice just strengthens the argument but the negation doesnt weaken.
https://gmatclub.com/forum/truesave-is- ... 72955.html is an example. In this question, my instincts said C must be the answer but following the process, I wasnt able to reach the answer. In addition, A also seemed a strong contender. Request your help on this.


Hey singh8891,

Here are a couple of posts on Evaluate questions:

https://www.veritasprep.com/blog/2016/0 ... reasoning/
https://www.veritasprep.com/blog/2016/0 ... s-part-ii/

This should help you get an idea on how to deal with them.

Here is a discussion on the question you mentioned:

Hey Guys,

I am travelling this week hence the responses might be a bit slow. Will try to keep up as much as possible.
Things will settle down next week onwards.

Hey Staphyk,

Different strategies work for different people. For some, reading the question stem first works. It helps them evaluate the argument as required. For others, it doesn't add a lot of value. You will need to figure out what works best for you but both strategies seem to work for different people so it is not a big distinction. Either is fine.
No matter what the question is, you should figure out what the conclusion/plan/proposal etc of the argument is. Then depending on what the question stem asks for, figure out your next step.

Can you please comment on this one - https://gmatclub.com/forum/in-a-recent- ... l#p2194617 . I am in a dilemma between option C vs. D

As always, you're the best. Thank you.

Hello VeritasKarishma Ma'am,

I have posted a small query to the same question on above forum after reviewing your answer. Thanks for the detail. I still had a small inch of doubt between C and D and hence I turned to you.
If you get time, will it be possible for you to review the same and let me know if the line-of-thinking what I have followed is proper?

Link: https://gmatclub.com/forum/in-a-recent- ... l#p2195011

The answer was correct, but I need to see if I got it correct for the right reasons.




Thanks & Regards,
Rishav

Hello VeritasKarishma Ma'am,
Thanks a lot for answering my previous query.

I was confused between few questions on strengthening where an option of comparison was given:
For example,
Consider the following set of questions ( MGMAT and OG ) :

1) https://gmatclub.com/forum/officials-of ... 12027.html

2) https://gmatclub.com/forum/the-heavy-tr ... 42147.html


Now if we consider the #1 question, we see that option E and option D both seem to strengthen and I was somewhat able tending to E, which eventually came out as right answer

Consider #2, we see that the correct answer Option C, ( since the other options do not come close and easy to draw conclusion)


Generally, it takes a bit time for me to rule out an option which compares the scenario/plan to another city/situation and this is a delta which usually takes time to choose the one of the prospective answers.

Is there a way or methodical logic that we can apply to rule out options which are based on comparison as in both the above cases, we saw that the answer differences were subtle.

I hope I am clear in my query, thanks in advance!!

Hey Rishav,

The distinction between the two questions is very clear - In the first one, the causation is not established.
A causation in a similar setting does strengthen the argument.

Say, city A is planning to establish plan X to achieve Y.
Other cities, which are similar to city A, did establish X to achieve Y and did achieve Y with it.
This does strengthen the possibility that establishing X will achieve Y in city A too.

This is what happens in the second question.

In the first question, the causation is not established. Did implementing suspension cause a decrease in the number of flagrant fouls in the similar league? We don't know. Perhaps the similar league has less aggressive players and hence lower incidence of flagrant fouls than the Youth Hockey League.
Since the causation is not established in option (D), it doesn't strengthen our argument.

Oh!! I did not get this in my first attempt!! Many thanks.

Just to re-iterate:
A similar league suspends players for committing flagrant fouls; this league has a relatively low incidence of flagrant fouls when compared with the Youth Hockey League.

So the bold part means that the incidence of fouls are low but the suspension might not be the cause of it.

Thanks, I was earlier seeing that as a causation!!

Yes, our minds tend to automatically assume a causation here even though it isn't mentioned. We need to be wary of this during the test.

Hi VeritasKarishma,

Can you please take a look at this - https://gmatclub.com/forum/necessity-fo ... 69128.html

Kindly let me know if E seems to you as a weakener based on CPA chick's reasoning quoted herein -
Yeah I agree with E 100%. If low performers can find other ways to climb the ladder (sycophancy, etc), then high performance resulting from a need for personal growth is NOT necessary for a successful career. But if low performers are weeded out then the only way to climb the ladder is to be a high performer.

What is the source for this question??? This is clearly the argument: "Need for personal growth is therefore an essential part of one’s career." Option "D" is completely out of scope for this argument. Even if D were true, so what? What does charity have to do with one's career?


I had similar reasoning and went ahead with E. Even though I know this is not an official question I am curious to know your thoughts on this one.

Thanks as always.

Regards,
Gladi

I am not convinced with this CR question at all. It doesn't make a lot of sense to me. What is the source?

Hello @VeritasPrepKarishma ma'am,

Regarding the question:

https://gmatclub.com/forum/psychologist ... 46659.html


I get why other options are strengtheners that is they really show that photographic memory is not a virtue that scientists show and with this thinking I came up with option D.

Though as per the discussions of the forum, they say it's a mild strengthener but I dont think so.

I believe it is a mild weakener.

The author says that due to media reports and " ill informed scientists" and based on this logic, the author say that photographic memory is kind of overhyped.

Don't we need to assume that the scientists thesis have to have sound credibility on the thesis of photogenic memory

I think this assumption is needed so that author counters this.

Option D thus falls short as it says it is already discredited and hence the author's reasoning is unnecessary or less relevant.

Am I correct with this line of reasoning? Please help.

Regards,
Rishav

Hello VeritasKarishma Ma'am,

Regarding this question: https://gmatclub.com/forum/many-athlete ... 20390.html

I have a small doubt.

Could you please explain:
"Measured continuously after exercise, however, the blood lactate levels of athletes who inhale pure oxygen are practically identical, on average, to those of athletes who breathe normal air."

The statement in the passage says on an average. Now
Let's call lactate level as BL and respective averages as:

Average with Oxygen = (BL1 + BL2+ BL3)/ 3

Average w/o Oxygen = ( BL1' + BL2') / 2
( Considering different sampling space)

Now considering above, we might come up with numbers such that the blood lactate levels on average looks same but they are not same as the sample itself is different as in take BL1 = BL2 = BL3 = 4 and BL1' = BL2' = 6, we get same numbers as lactate levels on average but the levels differ, then how we say A is an answer?

Based on the above reasoning, what am I missing here? Please help, thanks in advance!

Rishav

Hi VeritasKarishma

https://gmatclub.com/forum/a-newly-disc ... 32998.html

IN this question, I have a slight doubt in option B.
When we negate an assumption, the conclusion should completely be destroyed.
We are not looking to weaken the conclusion after negating the option.

The conclusion: The painting must have been completed between 1507 and 1509.

Premise: Coin not minted before 1507
Painting material not used after 1509

Option B: Michelangelo did not work on the painting over the course of several years.

Negated: Michelangelo did work on the painting over the course of several years.
Several years can be from 2 to many years. So can't we say that there is a possibility that the painting may have been completed by 1509. After all 1507 to 1509 (2years is also several years)
I totally agree that the negated statement weakens the conclusion.
But does it break it? I don't think so.

Would love to hear your opinion on this issue.

Thank you !

Hello VeritasKarishma Ma'am,

Regarding this question: https://gmatclub.com/forum/many-athlete ... 20390.html

I have a small doubt.

Could you please explain:
"Measured continuously after exercise, however, the blood lactate levels of athletes who inhale pure oxygen are practically identical, on average, to those of athletes who breathe normal air."

The statement in the passage says on an average. Now
Let's call lactate level as BL and respective averages as:

Average with Oxygen = (BL1 + BL2+ BL3)/ 3

Average w/o Oxygen = ( BL1' + BL2') / 2
( Considering different sampling space)

Now considering above, we might come up with numbers such that the blood lactate levels on average looks same but they are not same as the sample itself is different as in take BL1 = BL2 = BL3 = 4 and BL1' = BL2' = 6, we get same numbers as lactate levels on average but the levels differ, then how we say A is an answer?

Based on the above reasoning, what am I missing here? Please help, thanks in advance!

Regards,
Rishav


Hey Rishav,

All biological measurements will vary from one person to another. When we say the temperature of human body is 98.6, it is an average number. The normal body temperature for people may vary from 98 to 99 or even more.
The blood lactate level will also be an average. So BL1 will be different from BL2 which will be different from BL3. Similarly, BL1' will be different from BL2'.
If the averages in the two cases are the same, it means there is no statistical difference when pure oxygen is inhaled in the blood lactate level.
