- Past Perfect Continuous/Past Perfect or? 2 answers
I'm trying to figure out what to choose between Past Perfect Simple and Past Perfect Continuous in the following sentence:
Mr Georgiou had been working/had worked for the company for twenty years when he retired.
My choice was "had been working" because of the duration factor, "for twenty years". However, the book reports "had worked" as the correct answer. Isn't the above sentence emphasizing the duration of the action instead of the action itself?
