writingWhich choice completes the text so that it conforms to the conventions of Standard English?
A
visible
B
visible to be seen
C
visibly seeable
D
able to be seen visibly
Correct Answer: A
Choice A is the best answer. "Visible" means able to be seen; it is the most concise choice.
Choice B is incorrect because "to be seen" is redundant with "visible." Choice C is incorrect because "visibly seeable" is repetitive. Choice D is incorrect because "able to be seen visibly" is wordy and redundant.
