Almost every modern kitchen today is equipped with a microwave oven, mainly because microwave ovens offer a fast and convenient way of cooking and reheating food. Indeed, it has become a standard appliance in most households. Studies have shown, however, that microwave ovens are not completely safe and their use has occasionally resulted in serious injury. Because of this, some consumer advocates argue that microwave ovens should not be so readily accepted as a standard appliance until they can be certified to be completely safe.

The passage makes the premise that microwave ovens are not completely safe.This is followed by a conclusion by the consumer advocates that microwave ovens should not be accepted as standard appliances. Since there is nothing in the passage that provides an explicit link between the safety of microwave ovens and their acceptability as standard appliances, the consumer advocates’ conclusion is based on an assumption (i.e., an implied premise) that “an appliance should be accepted as standard only if it is found to be completely safe.” The most effective way to strengthen such a conclusion is to show that such an assumption is indeed true.
A. Microwave ovens have taken much of the joy out of cooking.- Irrelvant
B. There have been many reported incidences of people who have been scalded by liquids superheated in microwave ovens.- Providing a specific example of how a person might be injured, even seriously, by a microwave oven may provide emotional support for the consumer advocates’ position, but does little to strengthen the argument logically: the
possibility of injury has already been stipulated as a premise.
C. Absolute safety is the only criterion by which an appliance should be judged to be acceptable as “standard.”-Correct
D. There is no such thing as a completely safe appliance. - If no appliance is completely safe, then the consumer advocates’ argument is absurd: no appliance is, or ever will be, acceptable as “standard” in a modern kitchen. This choice weakens the conclusion.
E. Stoves and ovens that use natural gas consume energy much more efficiently than microwave ovens.- Irrelevant
Answer C
