Directions: Identify the segment in the sentence which contains the grammatical error.

You have written this poem yourself, is it?

The correct answer is 'haven't you'.

Key PointsA short question following a statement is called a question tag. It is used for checking information that we think we know is true. 

• The rules for making the question tag are:
• • The sentence and the question tag must be in the same tense.
  • For the negative question tag, use the contracted form of 'helping verb' and 'not.'
  • If the sentence is positive, the question tag must be negative and vice-versa.
  • Always use pronouns in the question tag.
    • Example: didn't, haven't, doesn't
• ​Therefore, the use of 'is it' in Part (4) of the sentence should be replaced by 'haven't you' to make it grammatically correct.
