___________________________
CR 1

Which of the following most logically completes the passage?

Federal officers analyzing the stagnant industries of the Alcappian region divided the industries into two categories: consumer goods manufacturing and the service industry. According to the analysts, unlike the service providers, most of the manufacturing companies in the region were not profitable. Some economists’ recommendation to focus federal aid on the service industry alone, however, will not necessarily improve the economic situation of the region, since ________.

A. most manufacturing industry companies have been in the Alcappian region for at least a decade, whereas some of the service companies were established in the region in the last decade
B. over the last thirty years, a third of the least profitable manufacturing companies have closed business, and their employees have emigrated from the Alcappian region
C. a significant portion of the revenue of service providers in the region is accounted for by contracts to manufacturing industry companies
D. Local service industry companies do not provide all the services needed by the companies in the Alcappian region
E. Neither industry has greater profitability, relative to the overall size of the industry, than the profitability of the ever-growing shipping industry in the region
___________________________
CR 2

Those who are suspicious of government attempts to regulate industry suggest that the well-being of workers would be better served if workers’ unions were established for each profession and radically empowered to establish and enforce the worker protection guidelines currently enforced by the government.

Which of the following, assuming that it is a realistic possibility, argues most strongly against the suggestion above?

A. Workers’ unions might compete for influence over the labor market.
B. Workers’ unions might not always agree on the best way to serve the well-being of the workers.
C. If they wished to expand their operations, workers’ unions might be forced to accept funding from private organizations.
D. Because of their lack of experience, many workers’ unions might not be able to establish better worker protection guidelines than the current guidelines established by the government.
E. Some groups of workers may continue to be mistreated despite the best efforts of the workers’ unions, even if the unions are not hindered by a lack of resources.
