1 一个化学家族,不代表有同样的作用 2survey 的可信度太低 3 M城的概念是哪里冒出来的? The arguer draw a conclusion that salibylates have effect on the cure the headache by a correlation survey. However, there are many flaws in it, on one hand, the survey dose not exclusive data of salibylates which only correlated with it. On the other hand, there is no logical sign to show if the salibylates are used as flavor additives, it can decline the number who suffered headache. The details of these flaws come after. To begin with, the premise of the conclusion is that salicylates have the same function as aspirin which is widely used as analgetic. However, what the attribute of salicylates is just of the same chemical family as aspirin which is not enough to show that they have the same function. For example, adamas and graphite are composed of the same chemical elements, but they have totally different nature. In addition, even salicylates can treat headache as well, it cannot guarantee without side effects as aspirin does. With the function which is not affirmatory of salicylates, the conclusion drawn in the end must be unconvincing. Granted that the salicylates have totally the same function as aspirin in treating headache, the survey is the main problem in different aspects. First, the salicylates are used as preservations means that it can preserve food turn bad, this application has no connection with headache. Then, the arguer directly say that salicylates has been found to correlate with a steady decline in the average number of headaches reported by participants in our twenty-year study. The survey lacks of many essential elements which persuaded us believe the result. For instance, the number of people, the chosen of people, and the condition of the survey are all not specific and assured. Without these indispensable data, the arguer cannot directly say the salicylates contribute to the decline of the number of people who suffered headache. What comes last is another conclusion that the decline of people who suffered headache in Mentia will decline because salicylates can be used as flavor addition. In the first place, the total text was not mention the strict of Mentia, and even the survey is not fixed in the area of Mentia, how can we assure Mentia has the same characteristic as the place where the survey does. In the second place, even salicylates can be used as flavor addition, n the second place, even salicylates can be used as flavor addition, the contribution of it to the steady decline of the number is doubtable because the dosage of it in foodstuff is fixed and cannot raise as people’ like. therefore, the discovery will not do good to the decline of the people who suffered headache. To sum up, the arguer has omission many essential data when he or she elaborate the survey to the public which may lead to the unconvincing in the end. Only with a believable survey, the conclusion based on it will has effect. |
