CR 2
As the lobbying activities of government contractors grow less regulated, the more contractors there are who resort to lobbying officials directly. Generally, government contractors who lobby to receive a particular project usually charge less for that project than those who do not lobby officials directly. Thus, if any of the government’s current restrictions are removed, such as the ones limiting campaign contributions to a certain limit, overall expenditure on government contractors will be significantly lower than if the state retains its current restrictions.
Which of the following, if true, would most seriously weaken the argument concerning overall expenditure on government contractors?
A. Recently, some other government restrictions that had limited the lobbying activities of government contractors were removed by the state.
B. It is unlikely that the government will remove all of the restrictions that apply solely to lobbying activities of government contractors.
C. Most government contractors who lobby officials directly to receive a project do not charge less for that project.
D. Most government contractors who currently limit campaign contributions to a certain limit would do so even if such a restriction were not in place.
E. Government contractors who do not lobby officials directly provide services of the same quality as those provided by the contractors who do lobby officials directly.
