og12 42 两个分词时态不一样，助动词不能省略吧

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

og解释两个分词并列，那应该是（was）spawned，（is）extending吧，时态不一样，不能省略吧

shallbytwo

这个是－ed分词和－ing分词分别做定语修饰tentacles。

winzeroJ

是两个分词。加was和is的话that引导的从句里就有好几个谓语了
