1 Factory workers in Beltania are guaranteed lifetime jobs， bonuses paid on the
basis of productivity and corporate profits， and a wage rate that is not attached
to a particular job. Paradoxically， these guarantees do not discourage factory
owners from introducing labor-saving machinery. Such innovations are to the
factory owners‘ advantage despite the fact that the owners must protect the
wages of their workers.
A Which of the following， if true， most helps to explain why the introduction of labor-
saving machinery is advantageous to factory owners?
B Before a Beltanian factory worker is hired， he or she must present a record
of his or her previous productivity.
C Labor-saving machinery increases productivity， thus yielding profits that
more than cover the cost of retraining workers for other jobs.
D The purchase and maintenance of new machinery adds significantly to the
final cost of the goods produced.
E Factory workers demand a change of procedure in the routine tasks they perform.
Limited competition exists among Beltanian factories for consumer markets.
