Final answer:
The grip with the shortest span is the ten-pin bowling finger-tip grip, where only the tips of the middle and ring fingers are inserted into the ball, along with the full insertion of the thumb.
Step-by-step explanation:
The question appears to be related to grips used in sports or physical activities, such as bowling, golf, or racquet sports. To answer the question: The grip that uses the shortest span between the fingers and/or thumb is typically the ten-pin bowling finger-tip grip. In this grip, only the tips of the middle and ring fingers are inserted into the ball up to the first joint, along with the thumb fully inserted, which provides a greater amount of control and spin on the ball but at a shorter span compared to the conventional or semi-finger-tip grips, where more of the finger is inserted into the ball.
