Question

Dogs bark at night, ...........................?

• A. wouldn't they
• B. don't they
• C. couldn't they
• D. mustn't they

Hint:

In tag questions, the verb in the tag must match the verb tense of the statement. For positive statements, use a negative tag like "don't they."

Answer 1

The Correct Option is B

Step 1: Understand the structure of tag questions.
Tag questions are small questions added to the end of a statement to confirm or check information. They generally follow the structure: a positive statement followed by a negative tag, or a negative statement followed by a positive tag. The verb in the tag must match the verb in the main clause.
Step 2: Analyze the options.
- (A) wouldn't they: This option is incorrect because the sentence is a general statement about dogs' behavior, which does not require the conditional form "would."
- (B) don't they: Correct. "Dogs bark at night" is a positive statement in the present tense, and the correct negative tag in this case is "don't they."
- (C) couldn't they: This option uses the conditional "could," which is incorrect in this context because the sentence is a general statement, not a hypothetical one.
- (D) mustn't they: This option would imply an obligation, which is not applicable to this sentence. Dogs do not have an obligation to bark at night.
Step 3: Conclusion.
The correct answer is "don't they" because it matches the present tense statement and forms a proper tag question.
