It might be worth rewording the Hint given with "... one of the industries that benefited the most from this new technology" > "... una de las industrias más beneficiadas de esta nueva tecnología".
It reads: "The adjective "new" refers to another or a newly-acquired technology rather than its condition". We were referred to Position of adjectives in Spanish - [reference number 6982] and I thought your hint implied that 'nueva' was acting to differentiate the noun 'tecnología' [i.e., to distinguish it from others] - rather than to 'emphasise' it.
