答案與題解：
1. B withdrawal 是個多義詞，在句子中的意思是“撤銷”或“中止”。
2. B 第二段中提到的兩個科學家認為，聯邦政府可以設定核設備的標準，以及頒發許可 證，但是州政府或地方政府在選址問題上應該有最終決定權。
3. D 第三段的第一個句子包含了 A、B 和 C 所述內容。
4. C 盡管第四段提到了尤卡山的確存在長距離運送核廢料的問題，但不是這段的主要內 容，所以 A 不是正確選擇。作者說，要在全國東西南北各地區建造核廢料處置庫，但沒 有說要盡量多的建造，所以 B 也不是正確選擇。作者想表達的意思是，要在全國各地區 建造核廢料處置庫，但州政府必須根據地方特殊情況制定方案，包括最后一句中所說的 “靠近核反應堆”的臨時處置庫。所以，C 是正確的。D 也不是作者的意思。
5. A This regional approach 的意思是：地域性方法，指的是前一段中所表述的內容， 即，地方政府應當考慮當地的特殊環境，對核廢物的處置地選擇負責。B、C 和 D 的表述 內容都是錯誤理解。
