I was marked wrong for 'These firms are in China' - exactly the same as 'companies'
It's been added, thank you very much. ^.^
Companies, firms, businesses... All correct, I think. In another exercise in this segment, the same word was translated by DL as "businesses" but here only "companies is accepted.
Really? All this has been included for this exercise as well and was last edited 6 months ago.
Why is "corporations" wrong?
