Did you have a bike when you were a child?
Candidato
When I was a child, I had a back and it was very useful for me because it could help me go to the school faster. But unfortunately I had to give it up because in the end I didn't use it all the time and my mother thought it was just a loss of money, a waste of money, so she sold it to other persons.

Do you think bikes are popular in your country?
Candidato
In my country, bikes are getting popular because we're talking about ecology and we start to think about polluting less, so the bike is very useful for that. It doesn't use any carbon dioxide, so therefore it's better for the earth.
Did you have a bike when you were a child?
Pontuação: 64.0Sugestão: Correct the word choice and grammar, make the answer more concise and structured. Start with a clear topic sentence, then briefly give one or two specific supporting details using linking words. Avoid redundancy (e.g., "loss of money" and "waste of money" together) and incorrect phrases ("had a back" should be "had a bike").
Exemplo: Yes, I had a bike when I was a child. It was very useful because it helped me get to school much faster. However, I stopped using it regularly, so my mother eventually sold it to someone else.
Do you think bikes are popular in your country?
Pontuação: 72.0Sugestão: Use clearer vocabulary and more precise reasoning; avoid inaccurate phrases (bikes "don't use any carbon dioxide" is incorrect — people don't emit CO2 while cycling). Begin with a direct opinion, then give two concise supporting reasons with linking words. Add a brief example or comparison to be specific.
Exemplo: Yes, bikes are becoming more popular in my country. Firstly, people are more environmentally aware, so they choose cycling to reduce air pollution. Secondly, cycling is cheap and convenient for short trips, for example many commuters now use bikes for the last mile to work.

The original uses 'back' instead of 'bike' (wrong word) and 'could help me go to the school faster' is awkward and mixes modal with general past habit. This fits sentence structure errors (ID 26). Use the correct noun 'bike' and simple past 'helped' for a habitual past action. Also remove the unnecessary article before 'school' ('to school' is correct). Suggestion: use 'helped me get to school faster.'
× But unfortunately I had to give it up because in the end I didn't use it all the time and my mother thought it was just a loss of money, a waste of money, so she sold it to other persons.
✓ But unfortunately I had to give it up because in the end I didn't use it all the time and my mother thought it was just a waste of money, so she sold it to other people.
The sentence contains awkward redundancy ('a loss of money, a waste of money') and incorrect phrase 'other persons.' This is primarily a word choice/idiom issue within past-tense narration (ID 5). Replace redundant phrase with 'a waste of money' and use the natural plural noun 'other people.' Tense (past) is correct: 'had to give', 'didn't use', 'thought', 'sold.' Keep consistent past simple.
× In my country, bikes are getting popular because we're talking about ecology and we start to think about polluting less, so the bike is very useful for that.
✓ In my country, bikes are becoming popular because people are talking about ecology and starting to think about polluting less, so bikes are very useful for that.
Original mixes progressive and simple forms awkwardly ('are getting popular' is acceptable but 'we're talking' and 'we start' clash). This fits present tense issues (ID 6). Use 'becoming popular' or 'are becoming' and parallel progressive forms: 'people are talking' and 'starting to think.' Also use plural 'bikes are very useful' for consistency. Suggest using 'people' instead of 'we' unless referring to the speaker's group.
× It doesn't use any carbon dioxide, so therefore it's better for the earth.
✓ It doesn't produce carbon dioxide, so therefore it's better for the earth.
'Use carbon dioxide' is incorrect collocation; bikes do not 'use' carbon dioxide. This is a verb choice/subject-verb collocation error (closest match ID 27 subject-verb agreement/usage). Replace with 'produce carbon dioxide' or 'emit carbon dioxide.' The negative 'doesn't produce' is correct for singular 'it' (the bike). Alternatively say 'they don't produce carbon dioxide' if referring to bikes in general.
