Am I Now Secure?

Update. After several emails to Apple Support, after trying to follow their directions and finding that I couldn't save my changes I sought help via Goggle. 

Help, I wrote, has anyone tried to change their security questions only to be unable to save the information?

It seems that a number of people suffered the same fate. Finally I found someone who offered a suggestion. Their list of steps-- half the eight steps the Apple Support Team proposed. 

It worked. I downloaded Peterson's Bird book and before long I listened to a raucous Red Billed Woodpecker.
