"What do the five men read?"
Translation:Cosa leggono i cinque uomini?
What about "the eight men"? Given the vowel in "eight" I presume "gli" remains: gli otto uomini. More generally: any adjective comes in between the noun and the article, the article changes in accordance with the starting vocal of the adjective? (i belli uomini?, gli aperti uomini? etc.)
