Band 6+: Are there any other inventions that make the world better?

Your pronunciation is average. It is understandable but not always accurate. Focusing on the rhythm and stress patterns of English could prove beneficial.

The response is relevant to the question and provides some examples of inventions that have improved the world. However, to achieve a higher score, the answer could benefit from expanding on the examples provided and exploring the impact of these inventions in more detail. A broader range of examples would also strengthen the response.

The answer is coherent, but the fluency could be improved. The phrasing 'to play a space in the air' is unclear and disrupts the flow. More concise sentence structures would enhance fluency.

The vocabulary is adequate but lacks precision. Words like 'gadget' are a bit general. More specific examples and sophisticated vocabulary would improve this aspect. The phrase 'crucial part of our daily existence' in the refined answer is a good example of more precise language.

Grammar is mostly accurate, with minor errors. The sentence structure is sometimes a bit simple. More complex sentence structures and varied grammatical forms would improve the score. The refined answer shows improvement in this area.
