Argument200 (210 xdf GRE写作教程)
Roberts and Human Workers
Outline:
1 efficiency: robots # guarantee efficiency
A, never sick but may go wrong
B, absenteeism and output: unjustifiable causal relationship =》A,B阻碍生产
C, 列举提高产量的其他可能因素
2 profitable: more output # more profits : cost and income
A, maintaining cost VS employ salaries
B, market situation and sales
3 unemployment instead of improving morale
4 success in outer space # success in factory work
In this argument the speaker concludes that the successful use of robots on missions to explore outer space in the past 20 years demonstrates that robots could be increasingly used to perform factor work more effectively, efficiently, and profitably than factory workers. For four reasons, these evidences lend little credibility to the speaker’s argument.
First, increasingly use of robots in factory work does not necessarily indicate more effectiveness or efficiency. In relying on the assumption that robots never get sick, the speaker concludes too hastily that absenteeism could be reduced and could, therefore, bring more efficiency in producing process than employing human workers. But the speaker fails to take into concern that robots may sometimes go wrong either because of program fallacies or direct human operating inappropriateness, which would hamper the producing process and reduce efficiency. Furthermore, less absenteeism does not equates with more output. The arguer simply ignores the possibility that the robots’ performance may not be as effective as human workers. In addition, the arguer fails to take in to account other factors in determining the total production such as the degree of adroitness of specialized workers. Without weighing these aspects, the speaker cannot justify the conclusion that more use of robots will bring about more efficiency.
Secondly, the arguer fails to build up a causal relationship between the increase use of robots and the increase in profits. The argument simply treats more output as more profits, which is unwarranted. Conversely, productivity is not the only attributes necessary in deciding a factory’s profits. In other words, the situation of merchandise market should be take into account as well as that of labor market. Perhaps the overuse of robots may give rise to oversupply therefore lead to lower price and lower sale. Or perhaps the cost for maintaining the robots exceeds the cost for employing human workers. Without ruling out these alternative factors, the argument’s reasoning linking between using more robots and more profits is unjustifiable.
Thirdly, the speaker asserts that many workers prefer to shift to more interesting works in supporting the point that the use of robots would improve the morale of factory workers. However, the speaker provides no evidence to substantiate this assumption. In fact, the use of robots may give rise to an abundance of jobless workers therefore add instability to society and things may just be the other way around. Accordingly, this evidence itself lacks credible support to the speaker’s theory about the several advantages in using robots.
Moreover, though the use of robots on missions of exploring outer space is successful, it is not comparable with factory performances. Hence there is no information available to justify and guarantee robots’ achievement in factories.
In conclusion, the argument is unconvincing as it stands. To strengthen it, the speaker must rule out the possibility that the use of robots cost more money and trouble than employing human workers. To better evaluate the arguments, we need more information in weighing the pros and cons of using robots, especially the maintaining cost.
