During the three months following this imposition, Marvel Automobile Company’s share of the Calistan market declined substantially even though its monthly sales within Calistan remained constant at the level reached in the last month of the ten-month period.

Marvel's sales remained constant while its share decreased, so the whole industry's sales increase. It means other companies' sales increase.
A for me

Let me try..!!!

Let say there are three manufactures in the Calistan,Marvel and other two ,B and A.
Let say total market MONTHLY sales of NEW CARS is 100 cars and this figure has remained constant for 10 month period(each month only 10 cars were sold).

Now Marvel has launched new cars and its share has increased, now Marvel share could only increase if share of A and B decreases (As the total market sales of NEW CARS is of 100, and to increase one's share we need to decrease the shares of other vendors )

Now, standards were imposed on new cars..

Now the share of Marvel has fallen, this can only happen EITHER if Marvel produce less cars and other vendors produce more cars (IF the total cars remain 100) OR Marvel produce same no. of cars and other vendors produce more cars than Marvel (The total no. of cars go BEYOND 100)

(A) The total monthly sales within Calistan of new cars by companies other than Marvel Automobile Company decreased over the three months following the imposition of the emission standards. >>> over the three months following the imposition >>> Already discussed above >>> Correct
(B) Over the three months before the imposition of the emission standards, the combined market share of companies other than Marvel Automobile Company selling new cars in Calistan decreased. >>> "Over the three months before the imposition" >>> We are here talking about the 10 month period, and we have seen in the 10 month period, the market share of other vendors have to decrease, if Marvel's share has to increase
(C) If the emission standards had not been imposed, Marvel Automobile Company would have lost an even larger share of the number of new cars sold in Calistan than, in fact, it did.>>> MAY be True >>> We cannot comment on the condition, which is not mentioned in the argument.
(D) A decrease in the total monthly sales of new cars within Calistan will occur if
the emission standards remain in effect. >>> MAY be True >>> "if the emission standards remain in effect" >>> This "if" clause here is the catch..!!
(E) Since the imposition of the emission standards, Marvel Automobile Company’s average profit on each new car sold within Calistan has increased. >>> Profit can increase as it will not affect and market share can still decrease. >>> CAN be true

OA Plz.

What was the source..I would not like to see these kinda on my test day..!!

Answer is A.

(A) The total monthly sales within Calistan of new cars by companies other than Marvel Automobile Company decreased over the three months following the imposition of the emission standards.
--- This cannot be true. As the stimulus clearly mentions share of Marvel Automobile company decreased during this period. This can be possible only by greater sales of cars by companies other than Marvel. Hence a potential contender.

(B) Over the three months before the imposition of the emission standards, the combined market share of companies other than Marvel Automobile Company selling new cars in Calistan decreased. --- This has to be TRUE. Before the imposition of standards if the market share of Marvel Automobile was increasing, then the share of other has to decrease. Hence potential loser.

(C) If the emission standards had not been imposed, Marvel Automobile Company would have lost an even larger share of the number of new cars sold in Calistan than, in fact, it did.
--- This can be OR CANNOT be true. Hence a potential loser.

(D) A decrease in the total monthly sales of new cars within Calistan will occur if
the emission standards remain in effect. ---Cannot predict. Hence can be or cannot be true. Hence a potential loser.

(E) Since the imposition of the emission standards, Marvel Automobile Company’s average profit on each new car sold within Calistan has increased. --- It can be or cannot be true. Discussion is regarding sale and market share. not related to profit.
