writingWhich choice completes the text so that it conforms to the conventions of Standard English?
A
eclipse. Also
B
eclipse also
C
eclipse; also
D
eclipse, also
Correct Answer: D
Choice D is the best answer. The comma correctly connects the non-essential participial phrase "known as totality" to the noun it modifies.
Choice A is incorrect because "Also known as totality" is a fragment. Choice B is incorrect because it lacks necessary punctuation to separate the modifier. Choice C is incorrect because a semicolon cannot precede a fragment.
