Thanks for these assignments texts!! I am a computer science professor here
in Brazil, I will use these questions on my exams!!
Ps: You were not willing that someone here would do the assignment for you,
did you????
Funny....

"Que o caminho seja brando aos teus pés;
Que o vento sopre leve em teus ombros;
Que o Sol brilhe cálido em tuas faces;
Que as chuvas caiam serenas em teus campos.
E, até que eu de novo te veja,
que a Deusa te guarde na palma da mão! "
