• Correct Answer: ক) He was ill, so he could not attend the meeting.
মূল বাক্য: "As he was ill, he could not attend the meeting."
- এটি একটি complex sentence কারণ এটি একটি subordinate clause ("As he was ill") এবং main clause নিয়ে গঠিত।
- Compound sentence-এ দুইটি independent clause কে যুক্ত করা হয় coordinating conjunction দিয়ে, যেমন: and, but, so, or.
ক) He was ill, so he could not attend the meeting.
→ দুইটি স্বাধীন বাক্য “He was ill” এবং “he could not attend the meeting” যুক্ত হয়েছে “so” দিয়ে। এটা সঠিক compound sentence.
Other options:
খ) Though he was ill, he could not attend the meeting.
→ এটা Complex sentence.
গ) He was ill but could attend the meeting.
→ ভুল কারণ “but” এখানে বিরোধিতা বা বিপরীত ভাব প্রকাশ করে, যা মূল বাক্যের সাথে খাপ খায় না।
ঘ) He could not attend the meeting although he was ill.
→ এটা complex sentence, কারণ “although” subordinate conjunction.
