Variables print

[PrologStudent1]

Hello everyone. I am currently coding a program that is supposed to get as input a clause, and write back ie the grammatical number or the time (past/future/present).

i.e. "The dog barks now." gives : Number: Singular, Time: Present.

the following is a part of my code, where it prints "Accepted" if the sentence given is syntactically correct.

check(Sentence) :-
  s(Sentence, []) -> write('Accepted\n')

s --> np(Number), vp(Number, Time).

What should I add in order to print as well Number and Time variables?

Thanks in advance!
