Answer 1

because we want people to think for themselves rather
than spoonfeed them everything.
When you start spoonfeeding them, they'll never learn
to think on their feet and will forever come here
with every tiniest problem.Original:
public class Spoon {
    public static Answer feed(Person me) {
        /* Implementation */
}New:
protected class Spoon {
    private static Answer feed(Person me) {
        /* Implementation */
}Problem solved.
