Hi !
<em>A. The answer is improved performance which is an effect of short-term exposure to stress. </em>
Researchers have found that wolves try lots of different trial and error tactics to solve the problem— they get at it physically. But at the first sign of trouble, dogs do something different. They look back to their human companion for help. This work hints that dogs may have lost some of their physical problem-solving abilities in favor of more social strategies, ones that rely on the unique sort of cooperation domesticated dogs have with humans. This also matches the work showing that dogs are especially good at using human social cues. Hope I’ve helped ;)
Your canine teeth are responsible for biting food.
Good Luck:)
