Hi
ExpertsGlobal, thanks for your answer.
I understand there is a difference in meaning between original sentence and D, but in the original question analysis it is mentioned that option E is correct dramatically (only the verb usage is incorrect), so what is the difference between D and E (apart from the wrong verb usage in E)? As E has been eliminated only because of wrong verb usage and it made use of 'the' I want to better understand the difference between D and E and what makes both incorrect.
D. The Microsoft founder, Bill Gates, and the Apple founder, Steve Jobs, are giants
E. Bill Gates, the Microsoft founder, and Steve Jobs, the Apple founder, had been giants
Thanks!
