I assumed 'company' as the intended synonym for 'institution', but that was not accepted
total doof, weil man nicht weiß, ob die Einrichtung als Organisation oder die Einrichtung z.B. eines Hauses gemeint ist
maybe it helps to think at the most clear sense of Set-up, we can set-up an institution (establish an organisation), but we can also set-up a house (furnish it)... it is more about arrangement - setting-up
I don't know! I put the same thing. It seems to me like furniture fits both the meaning for an arrangement and a furnishing which were the other options!
I have noticed that many times in these lessons you are given different options with the definition and when you input anything other than (usually not always) the first choice it comes back as incorrect.
