The question
20.

Which one of the following, if true, most contributes to an explanation of why the first alternative mentioned

Answer choices

  1. Half Scope3% picked this

    Since different parts of the transportation infrastructure are the responsibility of different levels of government, radical reconstruction projects are

    This might explain why radical reconstruction is costly, but does not explain continuous maintenance almost never happens.

  2. Too Weak / Out of Scope4% picked this

    When funds for transportation infrastructure maintenance are scarce, they are typically distributed in proportion to the amount of traffic that is borne

    This fails to add the rate at which the funds are distributed—all at once or a little bit continuously. Furthermore, it does not indicate the type of maintenance utilized.

  3. Enhances the Paradox13% picked this

    If continuous maintenance is performed at less-than- adequate levels, the need for radical reconstruction will often arise later than if maintenance had

    This is an advantage to continuous maintenance, making it all the more puzzling that it almost never happens.

  4. Enhances the Paradox2% picked this

    Radical reconstruction projects are, in general, too costly to be paid for

    This is a disadvantage to radical reconstruction, making it all the more puzzling that it continuous maintenance almost never happens.

  5. Correct79% picked this

    For long periods, the task of regular maintenance lacks urgency, since the consequences of neglecting it are very

    Why this is right

    This minimizes the long term negative effects of neglecting maintenance on transportation infrastructure.

    Skill tested: Paradox · how this choice captures the argument's function is the move to repeat next time.
