Answer:

I don’t know the last one
1. Once cuadernos.
2. Veintiun maestros.
3. Trenta y un mochilas.
4. Setenta y un estudiantes.
5. Cincuenta y siete clases.
Is yo conozco Espana! It isn't the second or the last one because se just doesn't fit. And the third one you could technaclly say but its not the correct way.
