Did you have a bike when you were a child?
점수: 50.0제안: Your answer is grammatically correct and concise, but it is too short and does not follow the Basic Structure requirement to provide a topic sentence plus supporting detail. To improve, give a brief topic sentence and add one or two specific supporting details (reason, brief example, or consequence) using a linking word to make it coherent. Keep it natural and no more than 3–4 sentences.
예시: No, I didn't. I grew up in a small apartment and my parents thought a bike would be unsafe for me, so they never bought one. As a result, I usually walked or took public transport to school.
Do you think bikes are popular in your country?
점수: 60.0제안: Your answer addresses the question but is informal and slightly ungrammatical (missing connector/punctuation). Improve by giving a clear topic sentence about popularity, then add a specific reason or example linked with a connective (e.g., 'however' or 'but') and avoid redundancy. Use a wider range of vocabulary (e.g., common/ widespread) and keep to 2–4 sentences.
예시: Yes, bikes are very popular in my country and you can see many people cycling in cities and towns. However, I personally never learned to ride one, so I couldn't take advantage of that trend when I was younger.
× Yes, very but I wasn't able to practice since I didn't know how to ride a bike.
✓ Yes, very popular, but I wasn't able to practice since I didn't know how to ride a bike.
The original reply omits the adjective that describes 'bikes' in response to 'Do you think bikes are popular...?' and instead uses 'very' without a linked adjective, causing an incomplete expression. Add the adjective 'popular' after 'very' to form the correct phrase 'very popular'. The rest of the sentence correctly uses past tense ('wasn't able', 'didn't know') to refer to a past inability, which matches the context. Suggestion: use a complete adjective after degree words like 'very' (e.g., 'very popular', 'very common').
