Description

Given a set $S$ of $n$ possible half-infinite, closed horizontal line segments, is there a non-horizontal separator?

Separator definition: Given a set $S$ of $n$ objects in the plane, we call a line $l$ a separator of $S$ if $l$ does not intersect any object in $S$ and both halfplanes bounded by $l$ contain a non-empty subset of the objects in $S$.
