Q1. Choose the most appropriate option to fill in the blanks: __________ postman's little boy said that he'd rather be __________ dentist than __________ cardiologist, because __________ dentists don't get called out at __________ night.
Explanation
The sentence refers to a particular postman, so 'The postman's little boy' is appropriate. With professions after 'be', the indefinite article is used: 'a dentist' and 'a cardiologist'. When a whole class is meant in a general statement, plural nouns take no article, so 'dentists don't get called out' is correct. The expression 'at night' also normally takes no article. The choices using 'A postman's', 'the dentist', or 'the cardiologist' either make the reference too indefinite or too specific, and 'the night' is not the idiomatic general time expression here.
