问题是，为什么B会awkward？过去式并列不是很好吗？
42. Scientists have recently discovered what could be the
largest and oldest living organism on Earth, a giant
fungus that is an interwoven filigree of mushrooms and
rootlike tentacles spawned by a single fertilized spore
some 10,000 years ago and extending for more than
30 acres in the soil of a Michigan forest.
(A) extending
(B) extends
(C) extended
(D) it extended
(E) is extending
Parallelism; Verb form
Th e original sentence is correctly written. Th e
giant fungus is described as an interwoven filigree
spawned … some 10,000 years ago and extending for
more than 30 acres. Th e present participle extending
parallels the past participle spawned.
A Correct. Th is sentence has the participles
spawned and extending in a correct parallel
construction. Spawned refers to something
that happened in the past, while extending
refers to something that continues into
the present.
B Extends is a present tense verb, not the
participle needed for parallel structure; the
ostensible parallel between extends and the
distant verb is is superficial and would result
in an awkward and unclear sentence.

根据prep笔记，现在分词表达的是修饰对象和分词之间有主动的含义，过去分词有被动含义。
要根据逻辑含义判断用现在分词还是过去分词。
根据BY，分词可以和分词并列。但没有说现在分词一定要和现在分词并列，过去分词也一样。

因为分词能修饰名词，动词不能啊

extends会和前面的is错误平行，这样就awkward了（ the
ostensible parallel between extends and the
distant verb is is superficial and would result
in an awkward and unclear sentence.）
