目的是要减少对对进口fuel的依赖，特别是首句关注的fuel是oil。
现在的情况是在heating上对fuel的需求已经开始从oil转为gas，且gas供给有余；oil的供给也在稳步上升。
关键就在于，对oil的需求会不会增长过快（比如除heating还有其他需要oil的地方）

n=8 k=12时 得8/12

我明白C 的意思，但是我就是觉得很牵强啊，所以我选了D ，有人能解释一下为什么D 无关吗？没迁徙记录这不就说明了很可能没狮子吗？以及，没有同行的目击者怎么就削弱了，他这是好几个目击者于不同的时间点目击到的，有没有人同行有什么要紧的？这个削弱也未免太不明显了吧

make一般约束力较强，用to do的形式

请问D选项伴随状语中making的逻辑主语是什么

“ In D, which seems to refer to an event, implying that our ancestors' numbers were reduced FROM an event -- a nonsensical meaning.”

'Comma + ING' represents 1. A consequence of 2. More information about the previous clause.
Generally, COMMA + VERBIng serves to express an action that is attributed to the nearest preceding SUBJECT and that occurs as part of the nearest preceding ACTION.
A and B: Lucretia Mott published her Discourse on Women, arguing in a treatise.
Here, the usage of COMMA + arguing implies that Lucretia Mott was ARGUING at the same time as she PUBLISHED.
This meaning is nonsensical.
其他地方看到的解释

个人感觉A选项里comma+ing的句子还是应该是一个状语从句（副词性修饰语），如果是ing形式的词作定语是不能带comma的。A的问题是在arguing对应的发出行动的主体是LM，在逻辑和语义上无法对应，一对比肯定是E选项 a treatise that argued for语义上更符合。“媒介”真的很有参考意义！
