Which of the following is NOT a type of bow?

The sling bow is not classified as a traditional type of bow used for archery. Instead, it is a device that combines elements of a sling and a bow to launch projectiles, typically using a rubber band or elastic material to propel an arrow or bolt. In contrast, the other options—compound bow, recurve bow, and long bow—are all recognized forms of bows commonly used in hunting and target shooting.

A compound bow features a system of pulleys or cams that make it easier to draw and hold at full draw, providing greater accuracy and power. A recurve bow has tips that curve away from the archer when unstrung, which contributes to its increased power and efficiency. A long bow is a simple, straight bow that is typically longer than the archer, relying on the archer's strength to draw and shoot. Each of these traditional bows is designed specifically for archery, while the sling bow bridges the gap between archery and slingshot mechanics.
