Question Tags:
A question Tag is a type of question form, which is added to a statement to invite the listener's attention to the statement. It is usually used in conversation. It serves the purpose of confirming out statements.
When a tag is spoken, the voice can go down or up and the meaning of tag depends on the intonation. A falling intonation indicates that the speaker is sure that the statement is true. Here the tag is not really a question.
