1. Which of the following most logically completes the passage?

Concerned about financial well-being of its elderly citizens, the government of Runagia decided two years ago to increase by 20 percent the government-provided pension paid to all Runagians over 65.  Inflation in the intervening period has been negligible, and the increase has been duly received by all eligible Runagians.  Nevertheless, many of them are no better off financially than they were before the increase, in large part because ________.

A.        They rely entirely on the government pension for their income

B.         Runagian banks are so inefficient that it can take up to three weeks to cash a pension check

C.        They buy goods whose prices tend to rise especially fast in times of inflation

D.        The pension was increased when the number of elderly Runagians below the poverty level reached an all-time high

E.         In Runagia children typically supplement the income of elderly parents, but only by enough to provide them with a comfortable living

2. A significant number of complex repair jobs carried out by Ace Repairs have to be reworked under the company’s warranty.  The reworked jobs are invariably satisfactory.  When initial repairs are inadequate, therefore, it is not because the mechanics lack competence; rather, there is clearly a level of focused concentration that complex repairs require that is elicited more reliably by rework jobs than by first-time jobs.

 

The argument above assumes which of the following?

 

A.      There is no systematic difference in membership between the group of mechanics who do first-time jobs and the group of those who do rework jobs.

B.       There is no company that successfully competes with Ace Repairs for complex repair jobs.

C.      Ace Repairs’ warranty is good on first-time jobs but does not cover rework jobs.

D.      Ace Repairs does not in any way penalize mechanics who have worked on complex repair jobs that later had to be reworked.

E.       There is no category of repair jobs in which Ace Repairs invariably carries out first-time jobs satisfactorily.
