"Animals are not humans."
Translation:Gli animali non sono uomini.
You can also say umano or essere umano. Generally uomo is for man, but you can pick up the difference the same way you can in English.
I suppose it is possible to debate the philosophical teachings that being with "Man is... (a political animal/the measure of all things...)" but the point is that these days that doesn't refer to the gender ;)
"Gli" is used before masculine plural words beginning with a vowel or with z or s + consonant, "i" is used before every other masculine plural word. http://www.bbc.co.uk/languages/italian/language_notes/il.html
Yes, it would be "animali sono", if it asked for "animals are", but this question asked "animals are not", so we have to negate it, thus we add "non". We invert the positive.
animali non sono
It will sink in after a while, the way the Italian language is structured (he attempts to convince himself!).
Damn annoying when you answer it in the positive, only to realise that you misread the question! Especially with no hearts left and you are on the last question!! lol... moments of insanity.... priceless ;)
