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.

Clearly A,C,E are irrelevant or will weaken the argument

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

Consider the opposite

The number of automobiles built by Deluxe each year has increased sharply since 1970. The argument points out that the durability of the cars is based on the longevity of the car. If they made only 1000 cars from 70-2000 and 200K in 2001-2005 and 100K cars are on the market, Is that durability caused by longevity? No.

Hence this is a good choice, even though this is more like a assumption. Assumptions are nothing but unstated premises that will strengthen the conclusion or needed for the conclusion to be valid, because with out the assumption the conclusion will fall apart.

D is saying that few changes have been done by Deluxe. sort of supports the argument. But not entirely because the durability in the argument is based on the longevity and not how many changes. Just because Deluxe chose not to change much over a long time does not mean that lack of changes (not lack of repairs/recalls) for a long time means longevity.

I will go for B as well.

An advertisement designed to convince readers of the great durability of automobiles manufactured by the Deluxe Motor Co 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 strengthens the argument

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 in the argument. We are taking about durability and number of vehicles on road. This one is out of scope.

B. The number of automobiles built by deluxe each year has not increased sharply since 1970
Suppose the company build 1,000 units each year till 2005(70,000 - Total) ,then 10,000 units each year till 2012(total 70,000) and the life of vehicle is only 5 years, then we can say the argument is invalid, as the evidence is deceiving(number of vehicles on road will be half of the vehicles manufactured since 1970). By saying that the number of units have not sharply increased, we can eliminate this possibility. So this is the correct option.

C. Owners of deluxe automobiles typically keep their cars well maintained
So deluxe automobile got lucky. This doesn't undermine the evidence.

D. Since 1970, Deluxe has made few changes in the automobiles it manufactures than other car companies have made in their automobiles.
The argument is about durability. If they are still using same parts and the consumer is accepting, still there argument and evidence holds true.

E. Deluxe automobiles have been selling at relatively stable prices in recent years.
Again, out of scope.

I am not convinced with the reasoning presented for option B. Rest all can be eliminated easily.

Explanation:
---------------------------
(A) After taking inflation into account, a new Deluxe automobile costs only slightly more than a new model did in 1970. ---> Irrelevant. We have to focus on durability.

(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. ---> What owners do is not important for the conclusion; what manufacturers do is important.

(D) Since 1970, Deluxe has made fewer changes in the automobiles it manufactures than other car companies have made in their automobiles. ---> When I looked at option D, it was a clear no-no for me. There could be other reasons why automobiles by Deluxe motor are still on roads. Only because they are still on road does not mean that they are durable. IMO, any product's life is directly proportional to how you treat it. Anyone can keep a car running for several years by getting it serviced regularly. But then how come Deluxe Motor is still in business? Though their automobiles may not be durable, they might be very fuel efficient. Who knows?

(E) Deluxe automobiles have been selling at relatively stable prices in recent years. ---> Not convincing. A stable price of a product does not guarantee that the product is durable. Moreover, how many years should actually be considered as ‘recent’?
---------------------------

My option choice is B. Though I could easily discard all but B by process of elimination, I'm not convinced about its reasoning.

I know what matters finally is answer but if you have the correct and convincing reasoning, nothing better than that!

Eagerly waiting for some concrete reasoning…

I am highly confused between B and D.
B- Production hasn't increased is a clear indication that the old cars are still on the roads.
D- Has not made many changes means that it has less chances of improving something and hence more durable.


D - It mentions DC makes fewer changes than it's competitors. These changes could all be related to durability, or maybe these changes aren't related to durability at all. If it's the first option, then DC cars were not durable, but if it's the latter, then they are reliable. This premise leaves us hanging, so B is the better option.

You can also try to negate B, and say that Deluxe did make more cars than they did in the 70s.
Well, if they are manufacturing more cars than before, more Deluxe cars will be on the road, and it severely impacts the conclusion that Deluxe Cars are more reliable.

Hope this helps.

Choice A, the cost is irrelevant to the durability issue.
C seems like a weaken answer.
E, the selling price is irrelevant to the durability issue
It's between B and D. But in D, made few changes does not seem to have anything to do with durability.

I guess I am going with B.

IMO D.

I think that B is offbeat.
The number of automobiles built by Deluxe each year has not increased sharply since 1970. - fine. but are they durable?

D says: they did little modification- it means that car requires less modification hence cars are indeed durable.

The potential changes made are not relevant. If B were false and they produced more cars then that might explain why more cars are on the road now. Since B eliminates this is a possibility (and therefore strengthens the argument), it is the correct choice.

By POE, I was confused between C and D and chose D with the following reasoning:

A. Cost is no way related to the durability.
B. Number is irrelevant here. The argument mentions "half of all the cars built".
E. Similar to A.

Between C and D, D mentions that since there have been fewer changes in the car, this supports the conclusion that more cars on the road is because of durability.

IMO B..........

since The number of automobiles built by Deluxe each year has not increased sharply since 1970 it means that the number of automobiles built by the company is still on the road, so ultimately it strengthens the agrument.

rest everyother choice, I feel is out of scope.

Advertiemnt says that half of all automobiles built by the company since 1970 are on road that support the fact of the durability of Delux automobiles.We should be looking for a statment that supports the durability.
A,B,C,E does not support.

D. Since 1970 Delux has made fewer changes to it automobiles it manufactures concludes that delux cars were durable and there was little to change.

I go with D.

Appreciate if some one could explain it a little better.

In B, there is a valid point to be made. They have not increased their production volume. May be other car manufacturers have decreased their volume; so this is unclear. Hence, B may be out.
In D, we are comparing with other automakers. Further note that deluxe has not made any dramatic changes to affect positively their durability. Hence, I go with D.

thanks.
initially went with D
i believe B is the answer, because B means --> we still have half of the cars running today is not because their number has been increased rather they are actually DURABLE?

IMO D.

all other companies might have changed their models so probably consumers changed them quickly. But Deluxe company didnt change anything so there is a chance that users might not have gone for the new models (new models dont have anything new since no changes).

Thanks.
