This test is sort of a silly and simplistic test. However, the point it is trying to make has some validity in my opinion.
One key point of Christianity is that ALL have sinned. No one is perfect. All of us, from the prisoner on death row to Pope Benedict, have failed to live up to the perfection that God desires.
That is what makes the grace of God that flows to us from the cross so wonderful. God loves all of us equally. He died on the cross so that His perfection could become our perfection. No one can boast of being better than anyone else. All are forgiven children of God.
For I am convinced that neither life nor death...neither the present nor the future nor anything in all creation will be able to separate us from the love of God that is in Christ Jesus our Lord. Romans 8:38-39
