arg把两个错误放在一段指出行吗？求助各位

就是把两个错误以并列或让步的关系放在一段，行吗？
71：Copper occurs in nature mixed with other minerals and valuable metals in ore, and the proportion of copper in the ore can vary considerably. Until fairly recently, the only way to extract pure copper from ore was by using a process that requires large amounts of electric energy, especially if the proportion of copper in the ore is low. New copper-extracting technologies can use up to 40 percent less electricity than the older method to process the same amount of raw ore, especially when the proportion of copper in the ore is high. Therefore, we can expect the amount of electricity used by the copper-extraction industry to decline significantly.
开头
1：没有证据表明新方法在铜含量比较低的时候也用电少。
2：即使是的，也没有证据表明用电量会减少。原因有两点：①：没有证据表明这种方法能够推广，可能并不实用；②：即使推广了，也可能由于其他原因导致用电量增加，比如说产量的提高，ore中copper含量的普遍降低。因此没有证据显示用电量减少。

从你举出的错误来看是可以的 只要能有逻辑联系

可是有另一个问题 我认为你举出的其中一到两条错误会有偏题倾向
参考此贴 再自己修改下吧

修改了一下，能帮忙看看不？

开头
1：没有证据表明新方法用电一定少，题目只给出了在高铜的情况下，没有给出在低铜的情况。
2：即使新的提纯铜方法用电少，也没有证据表明提纯铜产业的用电能减少。原因有很多，比如：①：作者没有提供任何关于新方法实用性的内容，很可能这种方法只能在实验室中实现，或者很贵等等，因此无法运用到实践中去；②：众所周知，用电量和产量和铜矿的质量有关，作者没有提供任何关于提纯铜产业以后的产量，铜矿的质量的内容。所以结论是不合理的
