Quite a few people have been asking me for help on AWA. So here goes - An actual GMAT AWA Sample Reply - (written by me under timed conditions in 25 minutes sometime in Dec '14 - Yes, I used to strain myself to deliver the entire 600 word ordeal in that much time)
"In order to avoid the serious health threats associated with many landfills, our municipality should build a plant for burning trash. An incinerator could offer economic as well as ecological advantages over the typical old fashioned type of landfill: incinerators can be adapted to generate moderate amounts of electricity, and ash residue from some types of trash can be used to condition garden soil."
Discuss how well reasoned... etc.
The argument that the municipality should build an incinerator for burning trash to avoid the serious health threats associated with traditional landfills is not entirely logical and convincing since it overlooks several key concerns that must be addressed in order to substantiate the argument. Moreover, the statements that follow the main conclusion offer discrete pieces of evidence to make a weak attempt to prove the main conclusion. These certainly do not lend support to the main argument and definitely do not prove its main conclusion.
More importantly, we do not get to see the line of reasoning employed by the author to support the main conclusion. We just see a few examples of benefits that offer a little support but fail to address the argument's main flaws. The argument is vulnerable to several important concerns as mentioned below:
First, the argument claims that the incinerator is beneficial since it provides certain economic and ecological advantages over the earlier method of using landfills. It provides examples to show how electricity can be generated and ash being produced can be re-used to condition garden soil. However, the argument fails to address the main concern of the people - the health threats. If the new incinerator causes more pollution or does not reduce the types of threats already posed by landfills, it will certainly prove not to be beneficial for the society at large. For example, using an incinerator may cause more air pollution as compared to dumping the waste in landfills and this is an important aspect that is not addressed in the argument.
Second, the benefits obtained from using the incinerator are again subject to concern. The by products from the incinerator, such as ash, if used to condition and fertilize garden soil can lead to other important disease causing problems if it subsequently mixes with the ground water supply and contaminates the same. There is a need to also identify the types of trash that will be burnt in the incinerator, since medical waste from hospitals and mortuaries would need to be disposed of with a high degree of caution.
Third, the argument does not also consider the kind of health concerns that the people are worried about and also does not mention any other benefits of using the incinerator. It seems that there is a trade-off between the two sides and certainly, more information is necessary to determine whether the incinerator would prove to be beneficial or would it prove to be an added concern for the society. By just mentioning two potential benefits, the conclusion that the incinerator is more beneficial is definitely not strengthened as there could be other disadvantages of its use that could overtake any positive aspects of its use.
Last, the argument also fails to consider any other possible options of the disposal of waste apart from incinerators and landfills. Also, there are several types of incinerators - based on whether they are open or closed to the atmosphere, the amount and types of waste they process, the efficiency of processing etc. Since the argument does not mention the specific type of incinerator being used, we cannot conclusively determine whether the usage of a particular type will be beneficial or not. Some types of incinerators may satisfy and help in the mitigation of health risks, while the others may not.
Since the argument leaves out several key issues, it is not sound and persuasive. It would have been more thorough it if discussed the items discussed above, instead of simply providing discrete pieces of evidence to make a weak attempt to prove the main conclusion. In order to decide whether the incinerator would be a good idea or not in a logical manner, we would require information about the demographics of the society, the kind of health concerns that people have and the benefits and disadvantages of using the incinerator. Only then can the argument be strengthened and all the flaws addressed to derive a sound conclusion. (662 words)
