writingWhich choice completes the text so that it conforms to the conventions of Standard English?
A
the 1880s he
B
the 1880s, he
C
the 1880s but he
D
the 1880s. He
Correct Answer: D
Choice D is the best answer. It correctly separates two independent clauses with a period.
Choice A is incorrect because it creates a run-on sentence. Choice B is incorrect because it creates a comma splice. Choice C is incorrect because a comma is missing before the conjunction "but," though D provides the clearest separation.
