Translation:Today the new national measures are in the newspaper.
"nazionale"= for singular, "nazionali"= for plural... So if you have many measures, it is plural, so you use "nazionali". In another example "la scarpa verde" means the green shoe but if you have more green shoes than verde becomes verdi and you say "le scarpe verdi". I hope this helps.
I don't see it on this page, but it sure seems like it must be. http://tutorino.ca/grammatica/2007/8/7/irregular-italian-nouns-3-nouns-that-change-gender-in-the-pl.html
O... M... G!!!
Needed to listen to this exercise a dozen times before I was able to type in the correct words.
For someone who's not used to listen to Italian, it's difficult to recognize the words when the sentence is spoken quickly and the speaker has the same high pitch throughout.
I hope Italians at large speak in more than a single pitch!!
