Correct Answer

খ) By whom were you taught English? ✅

Explanation:

• Who যুক্ত Interrogative Sentence কে Passive Voice এ পরিবর্তন করার নিয়ম:

  • Who → By whom হয়

  • তারপর tense ও subject অনুযায়ী auxiliary verb বসে

  • Object → Subject হয়

  • মূল verb এর Past Participle বসে

  • প্রশ্নবোধক চিহ্ন (?) বসানো হয়

Example:

• Active: Who taught you English?

• Passive: By whom were you taught English?

Other Options

ক) Who were you taught English by? → অনানুষ্ঠানিক ও অস্বস্তিকর গঠন; grammatically possible হলেও standard formal নয়।
গ) By whom you were taught English? → word order ভুল; interrogative না হয়ে assertive হয়ে গেছে।
ঘ) Whom were you taught English by? → “Whom” ঠিক আছে, কিন্তু standard formal usage-এ শুরুতেই “By whom” বসানো উত্তম।

সঠিক উত্তর — ক) Put the book back on the shelf.

• এখানে back verb (put)-কে modify করছে, অর্থাৎ "আগের জায়গায়" বা "ফিরিয়ে" দেওয়া বোঝাচ্ছে।
 এটি adverb।

Options:
খ) He was lying on his back on the sofa.
→ back এখানে noun (পিঠ)।

গ) We were sitting in the back row.
→ back এখানে adjective (row-এর অবস্থান বোঝাচ্ছে)।

ঘ) We drove along miles of twisty back roads.
→ back এখানে adjective (roads-এর ধরন বোঝাচ্ছে)।
