For every latitude number, there are two of them ... one "north" and one "south".
The question doesn't tell us which one is meant.
No part of anything in the US is south of 40° southlatitude.
The parallel of 40° north latitude traverses California, Nevada, Utah, Colorado,
Kansas, Missouri, Illinois, Indiana, Ohio, Pennsylvania, and New Jersey.
So we can accurately say that
-- Each of those states is partly south of 40° north latitude and partly not south of it.
-- Every state that's entirely south of any of those is entirely south of 40° north latitude.
-- Every state that's entirely north of any of those is entirely not south of 40° north latitude.
