Make industry rate a little more clear
The copper refinery  in "in a hot country" FIRS3, alpha 4, just says "(supplied)" next to delivered cargo to indicate it counts for increased production. This is not immediately clear.
It may be more clear when the text is changed to something indicating "(supplied, higher production)" or "(supplied, highest production)" 
: Likely there are many more industries
: Sorry for the boring text, but it's late.
