This scooter is not as efficient as it used to be; instead it is still a very useful machine.
EnglishSentence Improvement
- Asimilarly
- Bfurthermore
- Cnevertheless
- DNo improvement
Explanation
The sentence contrasts reduced efficiency with continued usefulness, so the concessive connector 'nevertheless' is needed. 'Instead' wrongly suggests substitution rather than contrast, and 'similarly'/'furthermore' express agreement or addition. Hence (C).
