`Do you know them?` বাক্যের passive form হচ্ছে-
Are they known to you?
Correct
Are they known with you?
Are they known by you?
Is they known by you?
Explanation:
Correct Answer is: Are they known to you?
Interrogative sentence কে প্রথমে Assertive sentence এ রুপান্তর করে নিতে হবে তারপর রুপান্তরিত Assertive sentence এর active voice থেকে passive voice এ পরিবর্তন করতে হবে। এবার রুপান্তরিত passive voice কে Tense অনুসারে Interrogative করলেই হবে। এভাবে করলে জটিলতা কমে যায়। Active Interrogative: Do you know them? Active Assertive: You know them. Passive Assertive: They are known to you. Passive Interrogative: Are they known to you?
