Government official: Currently many business travelers rely on a one-hour flight between the cities, but complain about congestion and delays at the airport. The new high-speed railway between Hamport and Dudley, Aplandia's two major financial hubs, will be able to make the same trip in slightly less than three hours. Given this option, many who fly between the two cities during the week will choose the railway, since it will allow them to travel between the city centers in less time than a flight with the expected delays plus the commute to and from airports would take. Which of the following, if true, would most cast doubt on his proposal above? ['Several trains will be scheduled throughout the day to accommodate a large demand should the route become popular.', 'The majority of those who commute between Hamportand Dudley say that they will continue doing so once the proposed railway is fully constructed.', 'Twice within the last two decades there have been significant recessions in Aplandia.', "The proposed speed at which trains are to travel will produce static electricity that will interfere with other trains' equipment, thereby causing significant delays."]
