Question

read the text. chewing your fingernails can be an issue not only for how your hands look, but for your health, too. your fingers may become infected, and your teeth may suffer damage. if you want to stop, its best to address nail biting with a combination of \carrots\ (positive rewards) and \sticks\ (adverse consequences). for a \stick,\ you can paint your nails with bitter - tasting nail polish or another bad - tasting substance. you can also try wearing a rubber band around your wrist and snapping the rubber band whenever youre tempted to nibble your nails. as a \carrot,\ treat yourself to a massage, yoga, or other stress - reducing activities. once youve succeeded in getting your nails healthy again, it should be easier to remember not to bite them. which organizational structure does this text primarily use? cause - effect problem - solution
