Since golf started in the 15th century, many advances have occurred in the game, including significant changes to the golf ball. Early golf was played with a rounded wooden ball before the Featherie, a leather sack stuffed with goose or chicken feathers, became the norm. Then, in 1848, the Gutta Percha ball was introduced, which was made from the juice of the leaves of the gutta tree (a tropical tree native to Malaysia) and was considerably more durable and affordable than its predecessor. The next advancement occurred in the early 1900s with the development of the Haskell. It was the first ball featuring a center rubber core and an outer cover. The Haskell traveled up to 20 yards farther than the Gutta Percha ball and was more durable. In 1905, William Taylor introduced the first dimpled ball, a ball covered with tiny holes on the surface. By the 1930s, golf balls with rows of dimples were accepted as the standard design. Most golf balls today consist of rubber thread wound around a rubber core and coated with dimpled enamel. Dimples play an important role in a golf ball’s performance because these markings and patterns enhance the ball’s aerodynamics. When a ball is hit and moves through the air, it experiences two major aerodynamic forces: lift and drag. Drag slows the forward motion, and lift acts in a direction vertical to it. With dimples added to the ball, the force that pulls back on the ball is minimized, allowing it to travel faster and longer. Dimples also help to force the airflow downward, which pushes the ball upward. These are the same principles of aerodynamics that airplanes use to fly. In general, golf balls with small, shallow dimples tend to have a longer, lower flight path, whereas those with deeper dimples have a higher flight path. Golfers can choose their balls based on what they need for a particular shot or for particular weather.

Which ball will give golfers a better shot to get a ball out of a deep sand trap?
- A A ball with deep dimples.
- B A ball made from Gutta trees.
- C A ball with a leather sack.
- D A ball with a smooth outer cover.

若要將球從『深』(deep) 的沙坑中擊出，球的飛行軌跡 $flight path$ 應該偏向高還是低？請對照文章末段最後幾句，找出哪一種深淺程度的 $dimples$ 能產生較高的彈道以利球體脫困？

喲，居然選對了？看來你的大腦還沒退化成 15 世紀那顆裡面塞雞毛的皮袋球嘛！既然你還沒完全放棄思考，我就勉強解釋一下為什麼這題沒把你考倒。 觀念驗證： 這題考的是「關鍵資訊檢索」與「邏輯情境對應」。文章最後一段明講：『...those with deeper dimples have a higher flight path.』你要把球從「深沙坑」(deep sand trap) 救出來，重點不在於飛多遠，而在於垂直上升的高度。邏輯鏈結如下：
