He tried about ten times before he had to stop . Being in the water in the shade had made him cold and when he lay down on a sun - heated rock , his lips were blue . I know Jo ?
What may have happened if he had not gotten cold ?
- His lips may still have been blue .
 - He may have been able to make more attempts .
 - He may have wanted to be in the sun .
 - He may have wanted to be in the shade longer .


He may have been able to make more attempts .
