- They couldn't hear me,.......? (Supply the correct question tag)
[tex] \huge \boxed{\mathfrak{Answer} \downarrow}[/tex]
- They couldn't hear me, could they?
- Here we used 'could they?' as the question tag because couldn't which is negative has already been used in the question. Then, the question has the subject as 'they' which is plural, so 'they' is also used in the question tag.
