The problem is so difficult that I cannot solve it.

→ Answer: The problem is too difficult to solve.

→ যদি Complex Sentence-এ "so...that" form থাকে, তাহলে Simple Sentence-এ রূপান্তর করার সময়:
- "so"-এর জায়গায় "too" বসবে।
- "that"-এর আগে পর্যন্ত একই জিনিস বসবে।
- "that" থেকে "not" পর্যন্ত অংশ উঠে যাবে।
- "to" যোগ করে বাকি অংশ বসবে।

→ "so...that" দিয়ে শুরু হওয়া Complex Sentence-এ দুটি clause থাকে:
Main Clause: The problem is so difficult.
Subordinate Clause: that I cannot solve it.

→ Transformation Rule অনুসারে Complex: The problem is so difficult that I cannot solve it.
