Question

human consumption is diminishing fish and shellfish populations so the world wildlife federation is advocating for stricter limitations on fishing
choose 1 answer:
a no change
b populations, so
c populations
d populations,

Explanation:

In English grammar, when joining two independent clauses (here, "Human consumption is diminishing fish and shellfish populations" and "the World Wildlife Federation is advocating for stricter limitations on fishing"), a comma - plus - coordinating conjunction (in this case, "so") is the correct punctuation. Option A has no comma before "so", which is incorrect. Option C removes the "so" and just leaves the two independent clauses, which is a run - on sentence. Option D only has a comma without the coordinating conjunction "so", which is a comma - splice error. Option B ("populations, so") correctly uses the comma - coordinating conjunction combination.

Answer:

B. populations, so
