**1. The question is:**

*P*on the set,

*A*, of all people, where

*xPy*means

*x*is a parent of

*y*.

## Homework Equations

- None**3. Attempts at a Solution**Here is where I am confused. Reflexivity is defined by

*aRa*. So I am unclear what to do with more than one variable. So in this question, do I examine if

*xRx*? That is to say is x a parent of x? If that is the case, then the answer is clearly no. I am just unsure of how to deal with reflexivity.

I am ok with symmetry and transitivity.
