Q32:不明白是怎么做出来的，求助一下大家

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 ______.

 

1. 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
2. many more people today than in the 1960’s habitually purchase and eat fruit without making an effort to clean residues off the fruit
3. people today do not individually consume any more pieces of fruit, on average, than did the people in the 1960’s
4. 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
5. 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

   Answer: A

主要看黄色部分，一开始有一个regulation, and then it will be replaced by another one. This newly established regulation will not allow more TDX(pesticide) into the market then the former one.所以一定是regulation的检验机制或者是技术一类的比原来的强或者比原来的严格使得这些无法上市，按照这个思路找答案就是A

A这什么意思呀，前1970 TDX残留检测技术可以检测到它，只有当它的量是比现在的新规则更多？好像跟我们所要的答案不是很相符诶～

就是说以前0.5才能显示为“含pesticide”(0.2,0.3这样的数都显示为"不含pesticide"), 现在的技术0.2啊0.3啊都能显示出来,但是显示达到0.5才不让上市。是吧~

小伊YSY

大概是
old regulation：只要检测到，就不上市
new regulation：若量过了某个标准（比如0.5）就不上市

那么A项是，1970前的技术，只有在量超过0.5时才有反应。所以old regulation也是只有在0.5或以上时才能被检测。
所以这个regulation相当于没改，所以TDX的量不会变更多。
