Step 1: Understand the meaning of "further."
"Further" is used to refer to additional help or support. In this context, the sentence suggests that no additional help is expected. Step 2: Analyze each option.
- (A) further: Correct. "Further" refers to additional help, making it the appropriate word for the sentence.
- (B) either: Incorrect. "Either" is used when talking about two choices, which doesn't fit here.
- (C) farther: Incorrect. "Farther" is used for physical distance, not for abstract concepts like help.
- (D) neither: Incorrect. "Neither" would imply that help from neither of two sources is expected, but the sentence doesn’t present two options. Step 3: Conclusion.
The correct sentence is "We can’t expect any further help from them."
