As *** pointed out, South Korean GDP grew by 770% between 1965 and 1995, while the economic and social structure of the nation dramatically changed, from an agricultural economy to a fully developed and highly technological industrial one, through various steps analysed in the following chapters.
Despite the general agreement on the outcomes of this developmental process, many different - and sometimes even contradictory - reasons have been brought forward to explain both the success of Korean policies and the 1997 crisis, which involved Korea as well as the other so called ‘Asian tigers.’
My questions:
1. fully developed and highly technological industrial one: is the sequence of adjectives correct? Does it need hyphens or any other change?
2. many different - and sometimes even contradictory - reasons, or 'many different, and sometimes even contradictory, reasons', or ... ?
3. Is it grammatically OK?
Thank you in advance!
