The statement:
A line in the plane of the ceiling and a line in the plane of the floor are __________ parallel.
Parallel lines are those lines which are coplanar but do not intersect each other anywhere.
Now, the line in the plane of the ceiling and a line in the plane of the floor will never intersect but the two lines will be parallel only if it is possible to draw a plane through those lines.
So,
A line in the plane of the ceiling and a line in the plane of the floor are sometimes parallel.
