@#@3.D根据题干中的信息提示词finalproduct，可将答案定位到D段，第二、三句提到最后的产品来源于纤维素纸浆。

@#@4.D根据题干中的信息提示词whitepaperandcard，可将答案定位到D段，该部分最后提到为了得到白纸，纸张生产者在制造过程中添加了漂白粉和其他化学物质。

@#@5.E根据题干中的信息提示词essentialforthetree，可将答案定位到E段，该部分提到木质素是木头的主要组成物，其作用是凝聚纤维素，但它会使纸张变得易碎。

@#@6.F根据题干中的信息提示词lignin，可将答案定位到F段，该部分最后提到许多纸张生产者在生产过程中会保留木质素，主要是因为它会增加树木的造纸产量。

@#@7.G根据题干中的信息提示词acid，可将答案定位到G段，该部分最后提到酸对相纸的原料尤其不利。

@#@8.F根据题干中的信息提示词lignin和paper可定位到文章的F段，因为该段提到，如果在纸张的生产中去除木质素，将会降低树木出产纸张的量，由此可以知道，去除了木质素的纸张价格必定会更加昂贵。

@#@9.K根据题干中的信息提示词cottonandragwaste可定位到文章的K段，该部分告诉我们，尽管用棉花和破布料造的纸里没有木质素，但它们要比木制的纸贵很多，这是因为棉花和破布料的数量比树木少得多，由此可以得出答案。

@#@10.M根据题干中的信息提示词PaperfromRa9可定位到文章的最后一段，该部分提出最好到专业的供应商那里去买档案材料，由此可以得出答案。
