Which of the following most logically completes the argument?
Ten years ago, the country of Benovia adopted new workplace safety regulations requiring protective equipment, improved training procedures, and upgraded machinery safeguards for all new manufacturing facilities. In the last few years, the annual number of factory workers hospitalized overnight or longer for injuries sustained on the job has been significantly lower than it was before the regulations went into effect. This evidence does not show that the regulations have made manufacturing work safer, however, since __________.Key to getting a Complete the Passage question correct is having a good setup before going to the answer choices. A good setup includes precise understanding of what the passage says and what the correct answer must do.
In this case, by considering the context and the keyword "since," we can see that the correct answer must show that, even though the annual number of factory workers hospitalized overnight or longer for injuries sustained on the job has decreased since the regulations went into effect, it may not be true that the regulations have made manufacturing work safer.
A. over the last ten years, production quotas have increased at many of Benovia’s largest manufacturing plantsIf anything, this goes in the wrong direction, indicating that the regulations may have made manufacturing work safer.
After all, if anything, an increase in production quotas could lead to an increase in injuries. However, as the passage says, the rate of hospitalizations decreased, rather than increased.
So, if anything, this choice indicates that there was some kind of improvement, which could have been due to the regulations.
Eliminate.
B. of the patients treated at hospitals in Benovia, the percentage being treated for workplace injuries has not decreased in the last few yearsIf anything, this choice shows that the regulations have made manufacturing work safer, doing the opposite of what we need.
After all, if the percentage of patients treated for workplace injuries in general has not decreased but the number of workers specifically from factories hospitalized for injuries has decreased, then perhaps something specific to manufacturing has made it safer. That could be the regulations.
Eliminate.
C. five years ago, hospitals in Benovia adopted stricter criteria for determining when a patient needs to stay overnightThis choice is interesting.
After all, if hospitals have adopted stricter criteria for determining when a patient needs to stay overnight, then it could be that the reason why the number of factory workers hospitalized has decreased isn't that their work has become safer but rather that, operating with stricter criteria, hospitals are generally less likely to have patients stay overnight or longer.
So, this choice indicates that the regulations may not have made manufacturing safer by indicating a possible alternative cause for the reduction in hospitalizations.
Keep
D. most manufacturing facilities currently operating in Benovia were built or upgraded within the past ten yearsSince the regulations require "upgraded machinery safeguards for all new manufacturing facilities," if anything, this choice is in line with the idea that the regulations did result in improved safety as manufacturing facilities were newly built or upgraded.
Eliminate.
E. the proportion of factory workers who regularly bypass safety procedures has changed very little since the new regulations were adoptedThis detail about what some workers have continued to do doesn't indicate that the regulations have not served to increase safety.
After all, the regulations could have made a difference in other ways.
Eliminate.
Correct answer: C
