Hello!
In the quiz there is the following true or false question
If $x$ and $y$ are element of an ordered set then either $x\geq y$ or $y>x$.
This is true. In fact we know that either $x>y$ or $x=y$ (it is not written that $x$ and $y$ are distinct :)) or $y>x$. Now OR has the associative property so we can see this statement as
($x>y$ or $x=y$) or $y>x$
and the satement in brackets can be written as $x\geq y$.
