Q32:
Which of the following most logically completes the argument?

Although the pesticide TDX has been widely used by fruit growers since the early 1960’s, a regulation in force since 1960 has prohibited sale of fruit on which any TDX residue can be detected. That regulation is about to be replaced by one that allows sale of fruit on which trace amounts of TDX residue are detected. In fact, however, the change will not allow more TDX on fruit than was allowed in the 1960’s, because ______.

A. pre-1970 techniques for detecting TDX residue could detect it only when it was present on fruit in more than the trace amounts allowed by the new regulations
B. many more people today than in the 1960’s habitually purchase and eat fruit without making an effort to clean residues off the fruit
C. people today do not individually consume any more pieces of fruit, on average, than did the people in the 1960’s
D. at least a small fraction of the fruit sold each year since the early 1960’s has had on it greater levels of TDX than the regulation allows
E. the presence of TDX on fruit in greater than trace amounts has not been shown to cause any harm even to children who eat large amounts of fruit


我完全不懂A在說什麼... :'(

是說1970前的技術只能檢測大於新規定裡微量的TDX，隱喻：
以前不可販售的規定值>現在新規定裡的微量值
所以this change will not allow more TDX on fruit than was allowed in the 1960's。

是醬子嗎？拜託幫忙∼∼∼

sandy你的觀念是正確的

早期1960 只要被detect有TDX residue on fruits被禁
後來 a regulation 允許在 traceable amount 以內的TDX 不會被禁

however, the change will not allow more TDX on fruit than was allowed in the 1960’s, because ______.

A)pre-1970 techniques for detecting TDX residue could detect it only when it was present on fruit in more than the trace amounts allowed by the new regulations　

1970以前 TDX traceable amount > new regulations 允許的 traceable amount

現在的technique更精準...少少的amount就可以測的出來
所以通過　with TDX residue on fruits 不會比以前來的多[/quote]

借用金剛的說法，第二段我的解釋改成這樣
1970以前技術只能測出>new regulations允許的traceable amount
舉例假設新規定是5%的殘餘就不行販賣，但以前的儀器只測得出超過5%的

所以以前規定雖然是只要有TDX redidue都不行販賣，但是因為只能測出超過
5%的(5%以下的測不出來，所以雖然有殘餘也不知道，照樣賣)，現在標準設
為5%，5%以下的殘存可以賣，所以雖然標準從0%放鬆至5%，但實際效果
一樣，殘存量5%以下的不管是1960s(技術造成)或1970s(法規造成)都可以販賣，只是原因不同而已。

不知道有沒有人覺得B選項也是可以
因為消費者已經習慣沒有TDX在水果上了 所以習慣eat fruit without making an effort to clean residues off the fruit
這樣一來 開放水果上能有TDX的劑量就不能太多 要低於人體可以接受的劑量也就是比the early 1960's更少的劑量

希望有好心的同學幫忙看一下 雖然我覺得正確選項A也是想的通 但B真的不行嗎?

[kaijen]

(B)為無關選項
消費者會不會在購買及食用水果時清理殘餘TDX
並不會影響果農要不要噴灑TDX
可能會-->因為可降低蟲害 增進收益
可能不會-->因為1960年代果農已經習慣當時的規定不得噴灑TDX了
我們不知道結果為何 因此(B)不可選

That regulation is about to be replaced by one that allows sale of fruit on which trace amounts of TDX residue are detected.
請問這裡裡從何可以看出""後來 a regulation 允許在 traceable amount 以內的TDX不會被禁""中的"以內"????
這句話每次都會翻譯成新的regulation是允許水果中有殘留TDX~~@ @
