Explanation: This exercise matches common English greetings and responses. Option 'b' is a standard reply to 'How are you?'. Losing a passport is unfortunate, so 'd' is an appropriate sympathetic response. Getting a new job is good news, hence 'a' for congratulations. The question 'It's a lovely day, isn't it?' is a statement seeking agreement, met by 'e'. 'Bye-bye' is conventionally answered with 'See you later'.
