The spokesman for the Ministry of Transport announced that the ministry has decided to pave roads with underground wiring as an alternative to spreading salt on the ice- and snow-covered roads. However, an official in the Ministry, who opposes the Ministry’s decision, was quoted saying that due to the high initial costs, the project cannot be cost-effective .
Which of the following, if true, most weakens the official's objection to the Ministry’s decision?
(A) Wiring roads has proved to be an effective means of preventing the accumulation of snow.
(B) Recent surveys indicate that ice-covered roads are the number one cause of car accidents in the winter.
(C) Last year, the Ministry of Transport spent a third of its budget on winter road maintenance in fuel, salt and personnel.
(D) Several countries, which have already wired their roads, still use salt as an additional measure.
(E) The price of electricity, on which the underground wiring system runs, has been increasing steadily over the past ten years.
OFFICIAL EXPLANATION
The spokesman for the Ministry of Transport announced that the ministry has decided to pave roads with underground wiring as an alternative to spreading salt on the ice- and snow-covered roads. However, an official in the Ministry, who opposes the Ministry’s decision, was quoted saying that due to the high initial costs, the project cannot be cost-effective .
Which of the following, if true, most weakens the official's objection to the Ministry’s decision?(A) Wiring roads has proved to be an effective means of preventing the accumulation of snow.
Incorrect.
To solve this Conclusion Weakening question, first break down the argument. The first sentence quotes a decision, presenting the Ministry of Transport's position. The next sentence has a reason conjunction (due to) which is followed by the premise (high costs) and then the official's conclusion.
The Ministry's Decision: build roads with underground wiring instead of using salt to clear roads
+
Premise A: there are high-initial costs
=
Official's Conclusion: this project is not cost-effective, i.e., wasteful
Possible assumption: nothing is saved by moving to roads with underground wiring
Weakening Data: ?
You are required to find data that weakens the official's view that the project is wasteful or supports the Ministry's decision. The correct answer could be one that exposes the argument's assumption.
This answer choice neither weakens nor strengthens the official's position as it does not discuss the cost of the project and its effectiveness in relation to that cost. The underground wiring system may be effective but if it costs too much it's not cost-effective.(B) Recent surveys indicate that ice-covered roads are the number one cause of car accidents in the winter.
Incorrect.
This answer choice neither weakens nor strengthens the official's position as it does not discuss the cost of the project, only its importance. According to this, either underground wiring in roads or spreading salt would do, as long as the roads are clear of ice.(C) Last year, the Ministry of Transport spent a third of its budget on winter road maintenance in fuel, salt and personnel.
This answer choice attacks the argument's assumption by showing that a third of the Ministry budget can be saved if the underground wiring is installed in roads. By doing so, the new system isn't just a waste of money - it also saves a fortune spent on road maintenance, a fact which weakens the officials objection.(D) Several countries, which have already wired their roads, still use salt as an additional measure.

Weakening Data: ?
You are required to find data that weakens the official's view that the project is wasteful or supports the Ministry's decision. The correct answer could be one that exposes the argument's assumption.
This answer choice supports the official's view by confirming the assumption that the underground wiring system does not save in expenses. If the roads still need salt to be cleared of ice, the underground wiring system is indeed wasteful. However, you were required to weaken the official's view rather than strengthen it.(E) The price of electricity, on which the underground wiring system runs, has been increasing steadily over the past ten years.
Incorrect.
This answer choice actually strengthens the official as it states that the price of electricity is rising. This makes the option of wiring roads more expensive. However, you were meant to weaken the official's objection by showing that the wiring system is not as wasteful as the official claims it to be.
