Answer
$1$, $parabola$, $2$, $parallel$, $2$, $below$.
Work Step by Step
Comparing the given equation $r=\frac{2}{1-sin\theta}$ with the standard form (d), we can identify that $e=1$, so this is the equation of a $parabola$. We see that $ep=2, p=2$, so the directrix is $parallel$ to the polar axis at a distance of $2$ units $below$ the pole.
