Because she had a reputation for —, we were surprised and pleased when she greeted us so —.

✅ কেন সঠিক: We were surprised and pleased, so her greeting was the opposite of her reputation. She was known for querulousness (complaining, being bad-tempered) but greeted us affably (in a friendly way).

❌ অন্য অপশন: Insolence–irately and arrogance–disdainfully are not contrasts; insouciance (carefree attitude) and cordially do not contrast either.

💡 মনে রাখুন: ‘Surprised and pleased’ = the behaviour was unexpectedly good. querulous = always complaining; affable = friendly, easy to talk to.
