What's wrong with "ultimi" instead of "scorsi"?
"Negli trenta minuti scorsi" - Why do we need "Negli" here instead of "Nei"?
I think this has to go with the scorsi and the need to use gli with. I am not 100% sure but that's my guess.
'Be careful not to confuse "trenta" and "30"!' - I ... they are the same thing.
Well for now there's going to be a lot of practice writing out the numbers until we (very soon) make it possible to use the numerals :)
Where is ultimi in the hover? What is durare mean?
