writingWhich choice completes the text so that it conforms to the conventions of Standard English?
A
distinct
B
distinct and different
C
distinguishable and different
D
identified as actually different
Correct Answer: A
Choice A is the best answer. "Distinct" effectively communicates that the element is different from others.
Choice B is incorrect because "distinct and different" is redundant. Choice C is incorrect because "distinguishable and different" repeats the same concept. Choice D is incorrect because "identified as actually different" is wordy and imprecise.
