× No, I hadn't.
✓ No, I didn't.
The examiner asked about a past habitual possession ('Did you have a bike when you were a child?') which uses the simple past auxiliary did for negatives and questions. 'Hadn't' is the contraction of 'had not' (past perfect or simple past of have) and is incorrect here because the simple past negative for 'have' uses did not have (didn't have). Use 'No, I didn't' or 'No, I didn't have one' to match the question's tense and structure. Suggestion: Use 'didn't' + base verb for past simple negatives: 'No, I didn't' or 'No, I didn't have a bike.'
× Yes, I think bike are popular in my country.
✓ Yes, I think bikes are popular in my country.
The subject 'bike' is singular but the verb 'are' requires a plural subject. The meaning refers to bicycles in general, so use the plural noun 'bikes' to agree with the plural verb 'are'. Alternatively, you could keep the singular noun with a determiner: 'A bike is popular' (but this changes meaning). Suggestion: Use plural form for general statements about a category: 'bikes are popular'.
