OG16 Verbal Review SC63 "able"语法点询问

Forrest_Gu

Many kitchens today are equipped with high-speed electrical gadgets, such as blenders and food processors, which are able to inflict as serious injuries as those caused by an industrial wood-planing machine.
(A) which are able to inflict as serious injuries as those
(B) which can inflict serious injuries such as those
(C) inflicting injuries as serious as that having been
(D) capable to inflict injuries as serious as that
(E) capable of inflicting injuries as serious as those

正确选项是E我没有疑问，只是在看OG解释选项A的时候，它说：

The term able suggests agency, which kitchen gadgets do not have.

这个语法点应该怎么理解和运用？

1、我认为这题的答案解释有问题，根据RON的视频课程，able用法同capable，既然E正确，那么A中的able用法也是正确的。

A中的主要错误有两点：1、句意错：A选项 :which are able to inflict as serious injuries as those，把整个宾语serious injuries 作为比较对象，意思是gadgets只能inflict一样东西——“严重的伤害”。                                                                                                                C选项：capable of inflicting injuries as serious as those，只比较injuries的严重程度，意思是gadgets会inflict很多种伤害——包括“严重的伤害”。
                                     2、描述简洁错：which are able to定语从句太wordy，可以直接用able to代替。


2、关于able/capable的用法

RON说过：able/capable的主语必须“有能力”做出这个行为。

WRONG: This sound is unable to be heard by human.
RIGHT: This sound can not be heard by humam.
RIGHT：Sound waves are able to shatter glasses.

非常感谢大神！可是不是说一切以OG的解释为准吗...OG的解释会错误吗？

而不，以OG的答案为准！但它的解释真是漏洞百出

G不上7不改名

Many kitchens today are equipped with high-speed electrical gadgets, such as blenders and food processors, which are able to inflict as serious injuries as those caused by an industrial wood-planing machine.
(A) which are able to inflict as serious injuries as those
(B) which can inflict serious injuries such as those
(C) inflicting injuries as serious as that having been
(D) capable to inflict injuries as serious as that
(E) capable of inflicting injuries as serious as those
A选项有没有可能是因为which 可能会指代不清，因为是非限定定语从句，有可能修饰gadgets 或者food processors。（》-《， 但是我没有找到具体的解答）
