Question: Read each of the passage and answer the question that follows it.
The problem of traffic congestion in Athens has been testing the ingenuity of politicians and town planners for years. But the measures adopted to date have not succeeded in decreasing the number of cars on the road in the city centre. In 1980, an odds and evens number-plate legislation was introduced, under which odd and even plates were banned in the city centre on alternate days, thereby expecting to halve the number of cars in the city centre. Then in 1993 it was decreed that all cars in use in the city centre must be fitted with catalytic converters; a regulation had just then been introduced, substantially reducing import taxes on cars with catalytic converters, the only condition being that the buyer of such a ‘clean’ car offered for destruction a car at least 15 years old.
Which one of the following options, if true, would best support the claim that the measures adopted to date have not succeeded?
Option 1 talks about the rise in the number of cars by purchasing second cars in the 1980s.
Many more cars were added as certain families without a car previously became first time car owners in the mid-1990s as mentioned in option 2.
Further on, post-1993, many people exchanged their 15 year old cars with ‘clean (with catalytic converters)’ cars from open market instead of getting their old cars destroyed, again adding to number of cars in Athens (option 3).
Therefore, all three options support that the measures taken, (cars with odd-even number plate driving on alternate days, destroying old cars etc) did not succeed.
Hence, the correct answer is option 4.
