The island country of Donia is severely polluted by nitrogen dioxide from automobile emissions. Because the vast majority of automobiles in Donia are owned by people who live in the capital city, the pollution is particularly heavy there. In order to significantly reduce the population's exposure to nitrogen dioxide, the Donian government is considering a plan to mandate that catalytic converters, devices designed to reduce such emissions, be installed on every automobile in the country.
Which of the following, if true, most strongly argues against the likelihood that implementing the plan would accomplish the Donian government's goal?
A. Nitrogen dioxide is not the major source of pollution to which residents of Donia are exposed.
B. The number of automobiles in Donia is unlikely to decline significantly in the foreseeable future.
C. The government's plan to mandate catalytic converters is likely to be strongly opposed by some members of the Donian legislature.
D. Most automobile trips in Donia's capital city are too short for the catalytic converter to reach its effective working temperature.
E. The average life of an automobile used in the capital city is shorter than the average life of a car that is mostly used outside it.

Question type: weaken the plan
Plan: Mandate catalytic converters on every car in the country to significantly reduce exposure to nitrogen dioxide.
Premise(s): The vast majority of cars are in the capital city. Catalytic converters are designed to reduce nitrogen dioxide emissions.
A. Nitrogen dioxide is not the major source of pollution to which residents of Donia are exposed.
The plan is not to reduce all pollution, it is to reduce exposure to nitrogen dioxide. This is out of scope. Eliminate.
B. The number of automobiles in Donia is unlikely to decline significantly in the foreseeable future.
How would this weaken the plan? Eliminate.
C. The government's plan to mandate catalytic converters is likely to be strongly opposed by some members of the Donian legislature.
This doesn't make it a bad plan. Eliminate.
D. Most automobile trips in Donia's capital city are too short for the catalytic converter to reach its effective working temperature.
If the vast majority of cars are in the capital, and most trips in the capital are too short for the catalytic converter to have the desired impact,...oh, that's not good for the plan! Keep it.
E. The average life of an automobile used in the capital city is shorter than the average life of a car that is mostly used outside it.
Out of scope, as there's nothing in the argument to suggest that vehicle age is an important factor. Eliminate.
Answer choice D.
