Consider  
the following Prolog code

```prolog

person(dana, sawad,
female, 40, chemist).

person(ahmad, abu_j,
male, 53, solicitor).

person(suna, jab,
female, 39, doctor).

person(osama, ahmad,
male, 43, architect).

person(sara, rami,
female, 30, engineer).

person(yazan, ali,
male, 27, programmer).

man(X):-person(X, _,
male,_,_).

woman(X):-person(X,_,
female, _, _).

whoisengineer(X):-person(X,_,_,_,
engineer).

canmarry(X,Y):-man(X),woman(Y),write(X),

    write(' can marry '), write(Y), nl.

cantreat(X,Y):-person(X,_,_,_,doctor),person(Y),

    write(X), write(' can treat '),
write(Y),nl.

```

Write a  
query to find whom can treat osama?

Write a  
query to check if ahmad is a man?

Write a  
query to find who can marry the engineer?

Write a  
rule that find all people who exceeds 50 years old, name it Above50().?
