3-The island of Madagascar,off the coast of Africa,is the habitat of more then 200,000 species of plants and [animals,many are not found anywhere] else on the planet.
a-
b-animals;many, not found anywhere
c-animals; of which man are not found anywhere
d-animals,many found nowhere
e- animals, finding many nowhere
Can someone please explain the correct answer ???

  1. D. It's the only answer that is an independent clause, which is required here, since there is no clause after the comma.
  2. D. The original is a comma splice. B and c leave fragments after the semicolon. E implies that the island does the finding, which makes no sense. D creates an appositive, with past participle "found" modifying "many," and that's just fine

But D creates a run on sentence since the two independent clauses are connected only by a comma.
Even in number 3 . How can the answer be D when the two indp clauses are only connected by a comma.
@WasatchWriter

I think you are mistaking participles for finite verbs.

I know that “many found” looks like s-v, but its not. Read it like “many of which are found”

Ahhh okay I got question 3 but can you clarify question 2 ? @WasatchWriter

Number 2 is clearly D
The other choices don’t even have a verb, so therefore, don’t even come close to making a complete sentence

Number 3 is also D.
B & C use a semicolon incorrectly. E is wrong bcs the island cannot be “finding”

“she being” is not a subject with a finite verb. “he [being] a dedicated bookworm” also lacks a finite verb. So there is no clause of any kind after the comma in 2. That whole phrase is an absolute.

Ahh okay. I got it

@gameplayer1233 and @WasatchWriter -

It’s also worth noting that (on the SAT at least) gerunds require genitive (possessive) pronouns/nouns, so “her being” is a permissible construction but “she being” never is.

Thank you @marvin100
