　　A recently issued twenty-year study on headaches suffered by the residents of Mentia investigated the possible therapeutic effect of consuming salicylates. Salicylates are members of the same chemical family as aspirin, a medicine used to treat headaches. Although many foods are naturally rich in salicylates, food-processing companies also add salicylates to foods as preservatives. The twenty-year study found a correlation between the rise in the commercial use of salicylates and a steady decline in the average number of headaches reported by study participants. At the time when the study concluded, food-processing companies had just discovered that salicylates can also be used as flavor additives for foods, and, as a result, many companies plan to do so. Based on these study results, some health experts predict that residents of Mentia will suffer even fewer headaches in the future.

　　Write a response in which you discuss what questions would need to be answered in order to decide whether the prediction and the argument on which it is based are reasonable. Be sure to explain how the answers to these questions would help to evaluate the prediction.

　　最近一项20年关于M地区百姓头痛的研究正在探寻水杨酸的潜在治疗作用。水杨酸酯和用来治疗头痛的药物--阿司匹林是同一类化合物。尽管很多食品天然富含水杨酸酯，食品加工公司仍然在食品中加入它来作为防腐剂。这种水杨酸酯在商业上的使用被发现与我们为期20年研究的参加者所报告的头痛发病的平均数量下降是相关的。但研究结束时，食品加工公司却刚刚发现水杨酸酯也可以被用作食品香料, 因此很多公司准备这样添加。依据以上的研究，一些健康专家预期Mentia居患头痛症的数量将会持续稳步下降。

　　写一篇回应，在其中讨论还有哪些问题需要被回答才能决定文中的建议以及得出这一建议的论证过程是合理的，并务请解释对这些问题的回答是如何帮助更好的评估文中的建议的。
