请教 OG13 SC 上的几道题

请问一下OG13 86题
86. In2000， a mere two dozen products accounted for half the increase in spending on prescription drugs, a phenomenon that is explained nt just because of more expensive drugs but by the fact that doctors are writing many more prescriptions for higher-cost drugs.
错误答案C a phenomenon occurring not just because of drugs that are becoming more expensive but because of doctors having also written

我想请问一下除了also的位置不对以外 OG的解释是doctors having also written   awkward and confusing 我想问一下是为什么


106 Originally developed for detecting air pollutants, a technique called proton-induced X-ray emission, which can quickly analyze the chemical elements in almost any substance without destroying it, is finding uses in medicine, archaeology, and criminology.

划线部分即使正确答案， 请问一下which不是就近修饰么 为什么可以跳过called----直接修饰a technique
而C A technique originally developed for detecting air pollutants, called proton-induced X-ray emmission, which can quickly analyze the chemical elements in almost substance without destroying it,   这里which为什么就是就近修饰emission.

讨论一下。

86 说“doctors having also written”   awkward and confusing 就是因为also的位置不对造成的，原来的意思是说原因不仅是药贵，而且医生喜欢开贵的药。C的意思就不对了，变成了而是医生也喜欢开贵的药。两种意思混乱了。

106 which可以就近修饰，但在逗号后面则多修饰于前一句，这里 which带的从句可以说是修饰A technique 也可以说是修饰proton-induced X-ray emmission，两者就是一个东西。C的错误在于A technique 放在最前面，整个逻辑意思都变了，而且造成了混乱。
