The supply of iron ore, the most important component in steelmaking, has been steadily declining in Marco city. This has forced steel manufacturing units in Marco city to source iron ore from far off mines leading to an increase in their transportation costs. Because transportation costs make up a large chunk of the total cost of steelmaking, the steel
manufacturers in Marco city have had no option but to increase the selling price of their steel. This has, in turn, led to an increase in the retail price of utensils and other articles of daily use made of steel. Since the retail consumers now have to pay more for these steel items, while their earnings remain unchanged, they have decided to cut down on their nonessential expenditure such as that on movie tickets. This has led movie theatres in Marco city to reduce their ticket prices.
Which of the following provides the most support for the assertion that the prices of movie tickets in Marco city will continue to decline in future?
(A) The people of Marco city will not be willing to cut down their expenditure on eating out.
(B) After the inauguration of the Goldport Bridge, expected to happen very soon, the transportation costs to Marco city will be halved.
(C) There are no blockbuster movies with stellar star casts lined up for release anytime soon.
(D) The supply of iron ore to Marco city is expected to go down even more in the near future.
(E) Residents of Marco city view movie tickets as non-essential items of expenditure.
Official Explanation
Answer: D
This argument consists of a series of cause and effects, wherein the effect of one event becomes the cause of another event. The last item in this chain is the reduction of movie ticket prices by movie theatres in Marco City. So, one entire chain of cause and effect has ended with movie theatres lowering their ticket prices. Now, why will the movie theatres lower their ticket prices even further? Only if the cycle of cause and effect were to start all over again and continue on and on. Since the cycle starts with the decline in supply of iron ore to Marco city, for the cycle to continue the supply of iron ore has to keep on decreasing in future as well. D states this and is the correct answer.
(A) Unless we are told whether the expenditure on eating out is essential or non-essential expenditure, this point will be irrelevant to the argument.
(B) This should actually weaken the argument by suggesting that the impact of reduced iron ore supply could be absorbed by the reduction in transport cost.
(C) The presence of blockbuster movies is outside the scope of the argument.
(D) The correct answer.(E) Even if this is so, the movie ticket prices should stabilize at their new low prices. Why should they go down further?
