Ans: BA city has been operating its public transportation system using diesel-powered buses. Currently, the number of buses in operation is just enough to meet the daily commuting needs of its residents. The city’s infrastructure does not support the immediate introduction of electric buses, and no new bus depots are planned for the near future. However, the population of the city is projected to grow significantly over the next decade, leading to increased demand for public transportation. Consequently, the city will need to import additional diesel-powered buses from neighboring regions to accommodate the rising demand.
Question:
Which of the following is an assumption on which the argument depends?
A. The quality of diesel-powered buses from neighboring regions is comparable to those currently in use by the city’s transportation system.
(Incorrect: The argument doesn't show concern over the quality of the buses, neither of the city nor of their neighbour city)B. Residents are unwilling to switch to alternative modes of transportation, such as cycling or walking. (
Correct: If we negate this " Residents are willing to switch", then it weakens the above conclusion of getting more buses to accommodate the increase in ridership)
C. The environmental regulations regarding diesel emissions will remain unchanged in the foreseeable future. (
IC: The argument doesn't mention anything about the env regulations)D. The cost of importing diesel-powered buses will not exceed the city’s transportation budget. (
IC: Cost is not discussed)E. There are no plans to develop alternative fuel sources for the city’s public transportation within the next decade. (IC: for same reason mentioned above)
Most of these options do not impact the link between the premises and the conclusion. Negation is a good way to go only when you have eliminated few straight wrong answers.
