Her car is as beautiful as mine. (Make it comparative)

Positive থেকে Comparative করার নিয়ম:
Structure: as + adjective + as যুক্ত positive sentence কে দুইভাবে comparative করা যায়:

Positive degree-এর Subject ঠিক থাকে এবং not less+ positive degree বসে।
- Positive: Her car is as beautiful as mine.
- Comparative: Her car is not less beautiful than mine.

অথবা,
Positive degree-এর Object- Subject হয়ে বসে+ not + comparative degree বসে।
- Positive: Her car is as beautiful as mine.
- Comparative: My car is not more beautiful than her dress.

সুতরাং, অপশন অনুযায়ী সঠিক Comparative হবে Her car is not less beautiful than mine.
