Answer
"Either Hari or Samira is reading in the same class, aren't they?"
The question tag "aren't they?" is a suitable choice for the sentence "Either Hari or Samira is reading in the same class" because it is a statement that suggests that one of them is reading in the same class. The tag "aren't they?" is used to confirm or seek agreement with the statement. By using "aren't they?" as the question tag, it is implied that the speaker is seeking confirmation or agreement from the listener that either Hari or Samira is indeed reading in the same class.
Here are some more examples to help illustrate the use of the question tag "aren't they?":
- He's coming to the party, isn't he?
- She's a great singer, isn't she?
- They have a lovely home, don't they?
In each of these examples, the statement is followed by a question tag that seeks confirmation or agreement from the listener.
