Question ID:PT81 S2 Q6 Passage:Astronomer: This country's space agency is currently building a new space telescope that is, unfortunately, way over budget. Some people argue that the project should be canceled. But that would be a mistake. If we cancel it now, all the money that has already been spent‚ which is more than the additional cost required to complete the project‚ would be wasted. Stem:Which one of the following principles, if valid, would most help to justify the astronomer's argument? Correct Answer Choice:BChoice A:A government agency should not cancel a partially completed project unless the amount of money already spent on the project is small relative to the agency's overall budget. Choice B:If more than half of the total cost of a project has already been spent, then the project should be completed. Choice C:If it becomes clear that the total cost of a project will be more than twice the amount originally budgeted, then the project should be canceled. Choice D:One should not commit additional funding to a project just because one has spent considerable money on it in the past. Choice E:In determining which scientific projects to fund, governments should give priority to the projects that are most likely to lead to important new discoveries.
