in several cities, the government is going ahead with ambitious construction projects despite the high office-vacancy rates in these cities. The vacant offices, though available for leasing, unfortunately do not meet the requirements for the facilities needed, such as court houses and laboratories. The government, therefore, is not guilty of any fiscal wastefulness.
Which of the following is an assumption on which the argument above depends?
