প্রশ্ন ৪৭: "This could have worked if I ___ been more far-sighted"

Answer: had ✓

Third Conditional — Past Unreal

If + past perfect (had + V3), would/could/might have + V3

Pattern

Main clause: This could have worked
If-clause:   if I [had] been more far-sighted

Main clause uses 'could have worked' (modal + have + V3) → if-clause must be had + V3 (past perfect).

Three Conditionals — Quick Reference

Type	Time	If-clause	Main clause
First	Future possible	Present simple	will + base
Second	Present/future unreal	Past simple	would + base
Third	Past unreal	Past perfect (had + V3)	would/could have + V3

Common Mistake

• ✗ If I would have known... (never use 'would have' in if-clause)
• ✓ If I had known... (correct)
