II - A line divides a plane into two parts;

III - Does a smaller sphere divide a larger sphere into two parts, like layers of an onion?

For the third statement, is the division of three-dimensional space into two parts correct?

IV - Could the straight line be an arc formed by a circle of infinite radius?
