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.

extended
it extended
is extending
还没有题目讲解（毕出老师会陆续发布对官方考题的解读，请保持关注）。
spawned和extending并列，共同修饰:an interwoven filigree of mushrooms and rootlike tentacles
spawned by 过去分词表被动，且是过去发生 10,000 years ago
extending现在分词表主动，且和过去对比，表示现在扩展的很广
BCE：把extend和 that is an interwoven filigree of mushrooms and rootlike tentacles 并列，不合逻辑
应该像A一样，先用一个定语从句主系表，说明fungus是an interwoven filigree
再用过分和现分两个修饰语，并列修饰fungus/an interwoven filigree
D：it extended和Scientists have recently discovered并列，完全错
难题，细节题
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.
