GMAT考试写作参考例文（22）

　　Second, the author assumes that the addition of the swimming pool was responsible for the increase in member usage. However, the only evidence for this claim is insufficient to establish the causal claim in question. While temporal precedence is one of the conditions required to establish a causal relationship between two events, by itself it is not a sufficient condition. Consequently, it is possible that the addition of the pool was unrelated to the increase in usage in the manner required by the authors argument.

　　In conclusion, the authors belief that adding additional recreational facilities will increase Take Hearts membership is ill-founded. To strengthen the argument the author would have to provide evidence that member usage is reliable indicator of new membership. Additionally, it would be necessary to show that the cause of the increase in usage was the opening of the new pool.
