logical deduction - 3 guards, 3 objects, 3 monsters and 3 questions

You are standing before 3 objects. You need to give the right one to the right monster or else you'll die.

There are 3 people in front of you for you to question.

One always lies, one always tells the truth, one varies between truth and lies, and you don't know which is which.

You can only ask 3 yes-or-no questions. How do you figure out which object goes to which monster?

EDIT: You are on a different planet, and you don't know the difference between "yes" and "no".
