Correct Option D

1990 editorial:
Premise: Local pay phone calls have cost a quarter apiece ever since the 1970s,
when a soft drink from a vending machine cost about the same.
The price of a soft drink has more than doubled since,
Conclusion: so, phone companies should be allowed to raise the price of pay phone calls too.
Editorial assumption: cost of Phone call and manufacturing of soft drink is same.

Which one of the following, if true, most weakens the editorial’s argument?

(A) A pay phone typically cost less than a soft-drink machine in the 1970s.
Wrong: supports the premise, but doesn’t give any strong reason to weaken the concluded argument.

(B) Due to inflation, the prices of most goods more than doubled between the 1970s and 1990.
Flaw: this gives more information about Inflation and price increase, if inflation would have impacted, it would have impacted all manufacturing segment approximately equally

(C) Government regulation of phone call prices did not become more stringent between the 1970s and 1990.
Flaw: Passage doesn’t discuss about Government regulation, and if does why Government regulation limit to only phone calls, it also makes argument strong, Now government regulation can be removed and bring to reasonable cost as per contemporary market situation

(D) Between the 1970s and 1990 the cost of ingredients for soft drinks increased at a greater rate than the cost of telephone equipment.
Correct: shows a crucial difference between the two commodities that form the basis for the author's analogy, and therefore weakens the argument

(E) Technological advances made telephone equipment more sophisticated between the 1970s and 1990.
Flaw: it only gives details about telephone equipment, on other side also raise a doubt, by technological advance was not able to bring same effect to soft drink machine, here comparison demeans the purpose.

70s, phone call cost = cost of soft drink
90s, 2 X phone call cost = cost of soft drink
=> phone call cost should be 2 times more.

The fallacy here is that author is not considering whether the two( phone call price, soft drink price) are independent or connected events. If they are not co-related there is no way one can influence the other.


(A) A pay phone typically cost less than a soft-drink machine in the 1970s.
Equipment cost is irrelevant to the argument. Eliminate

(B) Due to inflation, the prices of most goods more than doubled between the 1970s and 1990.
Prices of other products are irrelevant to the argument. Eliminate

(C) Government regulation of phone call prices did not become more stringent between the 1970s and 1990.
The data is inadequate and may or may not influence the argument. Eliminate

(D) Between the 1970s and 1990 the cost of ingredients for soft drinks increased at a greater rate than the cost of telephone equipment.
This can give the reason why the price of the soft drink rose when compared to phone equipment. Also, this is in line with our analysis. Keep

(E) Technological advances made telephone equipment more sophisticated between the 1970s and 1990.
This instead of weakening actually strengthen the argument. Eliminate

Hence, D is the best answer choice.
