automobiles

by crazy4gmat » Tue Nov 11, 2008 10:42 am
An advertisement designed to convince readers of the great durability of automobiles manufactured by the Deluxe Motor Car Company cites as evidence the fact that over half of all automobiles built by the company since 1970 are still on the road today, compared to no more than a third for any other manufacturer.
Which of the following, if true, most strongly supports the advertisement’s argument?
(A) After taking inflation into account, a new Deluxe automobile costs only slightly more than a new model did in 1970.
(B) The number of automobiles built by Deluxe each year has not increased sharply since 1970.
(C) Owners of Deluxe automobiles typically keep their cars well maintained.
(D) Since 1970, Deluxe has made fewer changes in the automobiles it manufactures than other car companies have made in their automobiles.
(E) Deluxe automobiles have been selling at relatively stable prices in recent years.

Why not D?

D convinces future buyers that only few changes have been made to the reliable automobile vis-a-vis the other company's cars.

Initially even i thot D to be the right answer...but i think B makes more sense.

Since the production capacity has remained almost the same and still more than half of the cars produced since 1970 are on the street today proves tht there are many cars which were produced in tht time that are seen on the street today..proving the durability of the car.

On the other hand in D wht if the production capacity of the company was less in 1970.....and now the production capacity is more....with few changes in the automobile... then it might be possible tht the cars we see on the road today are from the recent lot and not from 1970. thus not proving tht Delux Company car are durable.

I think my reasoning is right.

(A) After taking inflation into account, a new Deluxe automobile costs only slightly more than a new model did in 1970.

Cost is not mentioned

(B) The number of automobiles built by Deluxe each year has not increased sharply since 1970.

hmm...

I would go with B, because it means that the reason we still have half of the cars running today is not because their number increased but they are actually DURABLE



(C) Owners of Deluxe automobiles typically keep their cars well
maintained.

Weakens the argument


(D) Since 1970, Deluxe has made fewer changes in the automobiles it manufactures than other car companies have made in their automobiles.

It is tempting, but changes is till not in our scope


(E) Deluxe automobiles have been selling at relatively stable prices in recent years.

Cost is not mentioned

I think the answer is D.

D) Since 1970, Deluxe has made fewer changes in the automobiles it manufactures than other car companies have made in their automobiles.

If Deluxe has made fewer changes than other companies, that implies the parts that make up the automobiles are more durable.

Logitech,

I don't think your reasoning is sound. The paragraph states that "half of all autos built by the company since 1970 are still on the road today"... your defense of B says, "the reason we still have half the cars running today is not because their number increased, but because they are durable." Who cares about whether production increased in later years? The argument states that there are more cars FROM 1970 than other cars FROM 1970 produced by other manufacturers. [/quote]

I think I was paying attention to "since 1970" It does not mean that they are comparing the cars from 1970.

Logitech,

After re-reading the passage, I agree with you that they mean all cars produced from 1970 through present. But I still don't understand why you think B is correct. Can you further explain the logic?

Which of the following, if true, most strongly supports the advertisement�s argument?


(A) After taking inflation into account, a new Deluxe automobile costs only slightly more than a new model did in 1970.

(B) The number of automobiles built by Deluxe each year has not increased sharply since 1970.

(D) Since 1970, Deluxe has made fewer changes in the automobiles it manufactures than other car companies have made in their automobiles.

It is tempting, but changes is till not in our scope


(E) Deluxe automobiles have been selling at relatively stable prices in recent years.

Cost is not mentioned
lets say the present year is 1980, and the number of cars manufactured each year be 10,10,10,10,10,10,10,10,10,10 from 1970,
total =100; out of them it is very much possible that 50 cars are from the last 5 years and not from the first 5 years
how does this help in evaluating durablity

i will go with D .if i can make a reasonable assumption that less changes to the cars manufactured means the company has not compromised on durability aspect, D will strengthen the argument.Although it is not a great answer, it looks the closest..
Anyone ,please correct me if i have gone wrong somewhere. i have to learn from my mistakes
