Assume there is a class named Sushi implemented which overloads the > operator, by comparing a member variable in Sushi containing the price.  It returns a bool indicating whether the calling object is more expensive than the parameter object.  In the code below, assume that unagi and toro are valid instances of the Sushi class:

if (toro > unagi)

  cout < "unagi="" is="">

Which object is being passed as a parameter to the operator> function?
