PrepTest 52, Section 3, Question 20
There are two ways to manage an existing transportation infrastructure: continuous maintenance at adequate levels, and periodic radical reconstruction. Continuous maintenance dispenses with the need for radical reconstruction, and radical reconstruction is necessitated by failing to perform continuous maintenance. Over the long run, continuous maintenance is far less expensive; nevertheless, it almost never happens.

Which one of the following, if true, most contributes to an explanation of why the first alternative mentioned is almost never adopted?
Since different parts of the transportation infrastructure are the responsibility of different levels of government, radical reconstruction projects are very difficult to coordinate efficiently.
When funds for transportation infrastructure maintenance are scarce, they are typically distributed in proportion to the amount of traffic that is borne by different elements of the infrastructure.
If continuous maintenance is performed at less-than-adequate levels, the need for radical reconstruction will often arise later than if maintenance had been restricted to responding to emergencies.
Radical reconstruction projects are, in general, too costly to be paid for from current revenue.
For long periods, the task of regular maintenance lacks urgency, since the consequences of neglecting it are very slow to manifest themselves.
