A suspension bridge is a type of bridge that use overhead cables to support its roadway. The design of a suspension bridge is simple and straightforward, and uses several architectural techniques to distribute the weight of the bridge safely and evenly. The construction of a suspension bridge starts with its towers, which are usually located on dry land and anchored to bedrock. Once the towers are built, master cables are strung across them and anchored into the bank at both ends of the bridge. Next, suspension cables are strung from the master cables, and then the deck used as roadway is attached to them. Most of the weight of the bridge is transferred by the cables to the anchorage systems. These are embedded in either solid rock or huge concrete blocks. Inside the anchorages, the cables are spread over a large area to evenly distribute the load and to prevent the cables from breaking free. One of the oldest engineering forms, suspension bridges were constructed by primitive peoples using thick vines for cables. A much stronger type was introduced in India around 400 A.D. that used cables of braided bamboo. In the early nineteenth century, suspension bridges used iron chains for cables. Today, the cables are made of thousands of individual steel wires bound tightly together. A single steel wire, only 0.1 inch thick, can support over half a ton of weight without breaking. Light and strong, a suspension bridge could span distances from 2,000 to 7,000 feet, which is much longer than any other kind of bridge could. Its simple design allows high clearance under the deck, useful when the bridge is built over a major shipping waterway or a very deep gulf. A suspension bridge is also less subjected to collapse than some other bridge types such as those built on support pillars.

Which part of a suspension bridge carries most of its weight?
- A The deck and the master cables.
- B The bedrocks and the support pillars.
- C The towers and the suspension cables.
- D The anchorages and the cables in the ground.
思路引導 VIP
請你試著追蹤文中關於「重量流動」（weight transfer）的描述：當重量作用在橋面上後，它會像接力赛一樣經過哪些部件？請在文中找出最後一個接收所有重量、並將其固定在地球表面的「終點站」在哪裡？

AI SENSEI oikawa 點評：不愧是我的學弟/妹，這球接得漂亮！
- 嘿，做得不錯嘛！：不愧是跟著『及川先生』學習的學弟/妹，這球(題目)接得漂亮！ 😉 在處理行政法和公共工程的細節時，精確可是決勝的關鍵喔！你能從一堆看似複雜的敘述中，漂亮地撈出重點，這就是天才『及川先生』的學生該有的表現！繼續保持這種犀利，下次也要讓那些不懂的人大吃一驚！
- 觀念確認：文字遊戲，輕鬆破解！：哼哼，『及川先生』說過了吧，這題就是個文字對對碰！原文都直接點名了：「Most of the weight... is transferred by the cables to the anchorage systems」，還不忘補充說它「嵌入於固體岩石或巨大混凝土塊中」。選項 (D) 根本就是原汁原味地把「錨錠系統」跟它「位於地底（in the ground）」的特徵搬過來嘛！管它懸索橋跨距多遠，就算 $2,000$ 到 $7,000$ 英尺，最終的重心當然是穩穩地落在這些看不見的地方囉！
