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.

the passages claims great durability due to the evidence that 50% of all manufactured cars since 1970 are still on road compared with 33% of the other manufacturers. 

(A) After taking inflation into account, a new Deluxe automobile costs only slightly more than a new model did in 1970. 
out of scope, it is about durability and not price(B) The number of automobiles built by Deluxe each year has not increased sharply since 1970. 
this answer is teasing and close, but I think you can not conclude that a stable output streghtens the fact of durability. ( C) Owners of Deluxe automobiles typically keep their cars well maintained. 
weakens since it cites that due to maintaince and not durability the cars are still on road(D) Since 1970, Deluxe has made fewer changes in the automobiles it manufactures than other car companies have made in their automobiles. 
Yes, because they claim to produce cars with great durability and quality since 1970 until now, this strenghtens the argument!(E) Deluxe automobiles have been selling at relatively stable prices in recent years. 
out of scope, it is about durability and not price

i also picked D....if at all B is correct please explain me the reason...

I also picked D. But i think author wants to prove that though the automobile
numbers are not proportionally increased since 1970 , still the half of that company's cars are on the road to prove it's design durability and more.

A - not concerned. 

B - how does it matter. 

C - it would weaken the argument. 

D - right answer.  The company hasn't made any changes to the model since 1970 and there still the cars manufactures in 1970 are still on the road.  That means that the cars are durable since then. 

E - not concerned again.

I picked D. I used the Assumption Negation Technique I think.  If D wasn't true, it would mean they HAVEN'T made fewer changes to their cars relative to their competitors since the 70's.  They made the same amount of changes or more. 

Also, these could have been changes for the worse, or better... we don't know and we can't prove it.  But if they have made alot of changes to their cars, then maybe 100% of the >50% of cars that are still on the road are all from the 70's.  maybe they sold millions of durable cars in the 70's and only a few hundred thousand in the 80's until 2007.  and maybe all the cars from the 80s and 90's and 2000's all blew up.  follow my logic??  i hope i am correct on this questioni put a lot of thought into it!

spooky, B falls apart if the other manufacturers started producing less number of cars.  This can very well be a reason of less number of other cars on the road and nothing to do with the durability of the cars of this particular company.

I pick B - the fact that the company hasn't increased the number of automobiles drastically indicates that the older automobiles are still running fine, thereby stregthening the 'durability' angle..

Nice explanation. 

We cannot go with D because, D assumes that changing features is some way affecting durability.  That need not be the case.  A company for example might change the paint of the automobiles a thousand times without either increasing or decreasing durability.
