An automotive warranty claim occurs when a passenger car, sport-utilit

Chetan2u

I have slight reservation on choice B. Author has derived the conclusion based on relationship between warranty claims and manufacturing defects. Author cites evidence as survey of auto mechanics revealed that, for the years 2005-2014, nearly three times as many warranty claims were performed on sport-utility vehicles. Based on this, author concludes that sports-utility vehicle is more susceptible than light trucks.

So, any choice that leads me to believe this conclusion can very well strengthen the argument.

You said in your analysis that choice C doesn't talk about the comparison with light trucks. But it is also true at the same time that choice B doesn't talk of comparison.

Choice B merely states their ratio of total vehicle running on road. how this information can lead me to say that sports-utility vehicle is more susceptible.

Choice C states that number of warranty claims increased between so.. and so.. . This can tell some thing about the relation of warranty claims performed actually on sports-utility.

Could u kindly elaborate this?

An automotive warranty claim occurs when a passenger car, sport-utility vehicle, or light truck malfunctions because of a manufacturing defect. A survey of auto mechanics revealed that, for the years 2005-2014, nearly three times as many warranty claims were performed on sport-utility vehicles than were performed on light trucks. It follows logically, then, that sport-utility vehicles are more susceptible to manufacturing defects than are light trucks.

Which of the following, if true, most strengthens the argument made above?

A. Warranty claims on sport-utility vehicles are, on average, more expensive to perform than are those on light trucks..........expense or money does not affect the argument. OFS
B. Light trucks account for more than half the vehicles on the road..........This indicates that Sport vehicles are less in number but still claims are more implying that they are more susceptible to defects.
C. The number of warranty claims for sport-utility vehicles increased steadily each year between 2005 and 2014...........whether claims increase steadily or irregularly is not a point of concern. OFS
D. Passenger cars account for only 10% of all warranty claims.............passenger cars is completely out of scope.
E. 40% of sport-utility vehicles involved in one warranty claim required a second warranty claim..........second claim requirement because of first one cannot accounted for additional defect of vehicle. this option is not very clear.

Hi Chetan,

Any better way to Kill option D. I understand that option B is a better representation, but sport utility vehicle may be more susceptible to manufacturing defects not only because on the basis of volume produce (option B) but also on the basis of make (option C).

Any thoughts...

Choices A and E are weaken choices. Choices D and C are OUT OF SCOPE.

B makes most sense.

Hi,

Premise : An automotive warranty claim occurs when a passenger car, sport-utility vehicle, or light truck malfunctions because of a manufacturing defect. A survey of auto mechanics revealed that, for the years 2005-2014, nearly three times as many warranty claims were performed on sport-utility vehicles than were performed on light trucks.

Conclusion: that sport-utility vehicles are more susceptible to manufacturing defects than are light trucks.

Prephrase : if both SUV and light trucks account for same number of vehicles on road or light trucks are more than SUV in use then conclusion will hold. Otherwise the data presentation in argument will be wrong.

A. Warranty claims on sport-utility vehicles are, on average, more expensive to perform than are those on light trucks.
Ou of scope. The argument talks about number of claims not amount

B. Light trucks account for more than half the vehicles on the road.
matches with our prephrase , therefore supports conclusion. Lets say there are 100 vehicles on the road in which 51 trucks and 49 SUV and ,as given ,number of claims of SUV are 3 times of truck , clearly shows SUVs are more susceptible to defects.


C. The number of warranty claims for sport-utility vehicles increased steadily each year between 2005 and 2014.
This information has been given n the argument , therefore doesn't add any value to the conclusion

D. Passenger cars account for only 10% of all warranty claims.
Passenger cars are out of scope as comparision is between SUV and trucks

E. 40% of sport-utility vehicles involved in one warranty claim required a second warranty claim
Out of scope

need clear explanation for option E
if 40% of sport-utility vehicles involved in one warranty claim required a second warranty claim- same vehicles are prone to malfunction thus requires second warranty claim-shows suv are more prone to malfunction.

Type - strengthens
Boil it down - nearly three times as many warranty claims were performed on sport-utility vehicles than were performed on light trucks. It follows logically, then, that sport-utility vehicles are more susceptible to manufacturing defects than are light trucks.
- But our assumption is that number of SUVs is not significantly more than number of light trucks

A. Warranty claims on sport-utility vehicles are, on average, more expensive to perform than are those on light trucks. - ISWAT - we are only concerned about the number of warranty claims
B. Light trucks account for more than half the vehicles on the road. - Correct - So the remaining portion(less than 50%) accounts for passenger car and SUVs and thus SUVs form a smaller proportion of the total vehicles
C. The number of warranty claims for sport-utility vehicles increased steadily each year between 2005 and 2014. - Irrelevant
D. Passenger cars account for only 10% of all warranty claims. - Irrelevant
E. 40% of sport-utility vehicles involved in one warranty claim required a second warranty claim - Irrelevant

Answer B

An automotive warranty claim occurs when a passenger car, sport-utility vehicle, or light truck malfunctions because of a manufacturing defect. A survey of auto mechanics revealed that, for the years 2005-2014, nearly three times as many warranty claims were performed on sport-utility vehicles than were performed on light trucks. It follows logically, then, that sport-utility vehicles are more susceptible to manufacturing defects than are light trucks.

Which of the following, if true, most strengthens the argument made above?

A. Warranty claims on sport-utility vehicles are, on average, more expensive to perform than are those on light trucks. -We are not worried about the cost.
B. Light trucks account for more than half the vehicles on the road. -Correct. If the trucks account for more than 50% of the total vehicles, then smaller % of vehicle type having greater # of issues will surely suggest that the vehicle type with smaller % is dangerous.
C. The number of warranty claims for sport-utility vehicles increased steadily each year between 2005 and 2014. -We already know this from the argument.
D. Passenger cars account for only 10% of all warranty claims. -Irrelevant
E. 40% of sport-utility vehicles involved in one warranty claim required a second warranty claim. -Irrelevant

Premises:
Warranty claim occurs because of a manufacturing defect
Nearly three times as many warranty claims were performed on SUVs than on light trucks.

Conclusion: SUVs are more susceptible to manufacturing defects than are light trucks.

Note that the argument talks about the absolute number of warranty claims performed, not proportion. The first thing that comes to mind is that if there are many more SUVs than light trucks, there would be many more warranty claims on SUVs.
We need to strengthen the conclusion that "SUVs are more susceptible to manufacturing defects than are light trucks"

A. Warranty claims on sport-utility vehicles are, on average, more expensive to perform than are those on light trucks.

Cost is not discussed in the argument.
If some people don't claim warranty, they could belong to either category - light trucks or sport utility vehicle.
One factor is cost, another could be laziness, yet another could be unavailability of a dealer close by etc.
Hence, more expensive SUV claims may not be a valid reason to have more SUV warranty claims. And yes, just because SUV claims are "more expensive", it doesn't mean that light truck warranty claims are cheap.

B. Light trucks account for more than half the vehicles on the road.

This means that number of SUVs is certainly less than the number of light trucks. But we have more warranty claims of SUV. So this certainly gives more credit to the conclusion that SUVs are more susceptible to manufacturing defects than are light trucks. Say if there are 40 SUVs and 55 light trucks, we still see 10 SUV warranty claims as against 5 of light trucks. So it seems that SUVs are more susceptible to manufacturing defects than are light trucks.

C. The number of warranty claims for sport-utility vehicles increased steadily each year between 2005 and 2014.

The fact that number of warranty claims for SUVs is increasing steadily doesn't matter. We know that number of warranty claims of SUVs has been higher.

D. Passenger cars account for only 10% of all warranty claims.

Irrelevant

E. 40% of sport-utility vehicles involved in one warranty claim required a second warranty claim.

This has no impact on our argument. Every warranty claim could be counted as a manufacturing defect. SUVs suffer from more warranty claims - whether the claims are on the same vehicle or different vehicles only, doesn't matter. More warranty claims does imply more manufacturing defects, even if they are in the same vehicle.

Answer (B)

If there are more light trucks that SUVs n yet claims of SUVs are more, then conclusion strengthens.

Hence B

VeritasKarishma

I eliminated B because it merely says Light trucks account for more than half the vehicles on the road. We don't know whether this piece of information is valid for the 2005-2014 timeline on which the argument is based.
It could be possible that light trucks have become frequent on the road only recently (say, since 2018).
On what basis do we assume that what we see today on the road is representative of what it was during 2005-14?

D, on the other, tells me there has been a steady increase in warranty claims for SUVs between 2005-2014, which rules out the possibility of any anomalous year (for example : a certain defective machinery in a manufacturing plant resulted in a large batch of defective SUVs in 2013, contributing to a significant majority of the claims for the years 2005-2014, although the other years have been mostly claim-free).
This option sounds more convincing to me because it shows evidence of a general trend during the timeline in question.

Where am I going wrong in my reasoning?

Thanks

A. Incorrect. There is no comparison of expenses.
B. Correct. If there are more number of light trucks than SUV and still SUV has more warranty claims, it is indeed true that sport-utility vehicles are more susceptible.
C. Incorrect. We are talking of comparing between light trucks and SUV.
D. Incorrect. Passenger cars is not relevant.
E. Incorrect. A weakener rather than a strengthener.

(B) Light trucks account for more than half the vehicles on the road.
is given as a general statement, a fact.
We can expect it to be true during 2005-2014 time period too.

As for (C) (not D), even if the warranty claims have been increasing steadily, how does it support that SUV's are more susceptible to defects? Perhaps number of SUVs has been increasing steadily that is why the claims have been increasing. The point is the comparison between SUVs and light trucks and this option does not help us.

Option (B) tells us that there are many more light trucks (so fewer SUVs) but fewer claims on light trucks. So it does seem that SUVs are more susceptible to manufacturing defects.

Answer (B)

this was a fairly easy one we have to stick to claim that makes us understand that the trucks are less suspectable than suv thus can be only naturally followed if trucks are more then they aren't getting more complaintaints then thay aren't so damaging ..
