Which choice best reduces the ambiguity of the sentence?

A

On the signs, they warn

B

The signs warn

C

They warn on the signs

D

On the signs, he warns

Correct Answer: B

Choice B is the best answer. "The signs warn" clearly attributes the action to the noun.

Choice A is incorrect because "they" is vague. Choice C is incorrect because "they" is vague. Choice D is incorrect because "he" is vague.
