"academia" or "the academia"; "industry" or "the industry" [closed]
Solution 1:
Only the second is correct.
"Academia" is a proper noun (although it is not always capitalised) and thus is incapable of being qualified by "the".
OED
Etymology: Partly < classical Latin Acadēmīa academy n., and partly < classical Latin Acadēmus (ancient Greek Ἀκάδημος ), name of the Attic hero in whose grove Plato's Academy was situated;
The industry can only be used if a particular industry has already been mentioned.
You intend "industry" to mean "industry in general", and therefore the unqualified, uncountable noun is required.
