1. What are the advantages of shoot at a higher ISO at a sporting event like basketball or a night football game? It capture the image quicker and freezes the motion of the players. 

2. What suggestions did the author make about using a low ISO? When there is plenty light, use the lowest ISO to capture the highest image quality. Only use low in some dim  or dark places if you're mounted on a tripod or sitting the camera flat.
3. What suggestions did the author make about using a high ISO? Increase ISO when there's not enough light for the camera to capture the image. Increase to higher ISO if you need to freeze the motion and capture a very quick image.
4. At the camera near you, please tell me what ISO's are available on your camera?
