Options: (ক) By whom the work was done? • (খ) Whom had the work done by? • (গ) By whom was the work done? ✓ • (ঘ) Who was the work done?
Wh-question-এর voice change-এ এই ক্রম অনুসরণ করুন:
Active: Who did the work? Step 1: Who → By whom Step 2: did = past-simple → was/were + V3 Step 3: the work = singular → was Step 4: done (V3) Passive: By whom was the work done? ✓
| Active (wh) | Passive (wh) |
|---|---|
| Who broke the glass? | By whom was the glass broken? |
| Who wrote this book? | By whom was this book written? |
| Whom did you call? | Who was called by you? |
| What did he say? | What was said by him? |
| অপশন | দোষ |
|---|---|
| By whom the work was done? | Interrogative structure ভাঙা — auxiliary সামনে আসেনি |
| Whom had the work done by? | Tense ভুল (had ≠ did); structure বিশৃঙ্খল |
| By whom was the work done? ✓ | Wh + auxiliary + subject + V3 — সঠিক |
| Who was the work done? | 'Who' subject হিসেবে রেখেছে, by-agent নয়; preposition 'by' উধাও |
'Who'-কে 'Whom' হিসেবে বদলে নিন না — 'Who' active subject → passive 'by whom' (by + objective form)।
| Tense | Passive auxiliary |
|---|---|
| Present simple | am/is/are + V3 |
| Present continuous | am/is/are being + V3 |
| Present perfect | has/have been + V3 |
| Past simple | was/were + V3 |
| Past continuous | was/were being + V3 |
| Past perfect | had been + V3 |
| Future simple | will be + V3 |
| Modals | modal + be + V3 |
'Who → By whom + auxiliary + new subject + V3 + ?' এই ৫ ধাপ মুখস্থ। 'Who' কখনো 'Whom' হবে না active→passive-এ।
