Re: each other I agree with Coffa's post. The correct choice is (B):
(B) I couldn't hear the other's voice.
Here "the other's voice" is short for the other person's voice.
Choice (A), each other's, doesn't fit. It's a reciprocal pronoun; it refers to more than one person, e.g., they, we:
(A) We/They couldn't hear each other.
"each other's" doesn't work with the singular pronoun "I".
The same holds true for choice (C). "one another" requires a plural pronoun:
(C) They/We couldn't hear one another.
Choice (D) doesn't fit. "each" refers to more than one, so a plural pronoun, not a singular one is required. Moreover, "each's" isn't Standard English. "each" can be a determiner and a pronoun, and those forms cannot take apostrophe, -'s.
(D) *We/They couldn't hear each's voice. <ungrammatical>
Hope that helps. |
