想要請教各位Q__Q ----------------------------------------------------------------- Paragraph 3 With question such as these clearly before them, the scientists aboard the Glomar Challenger processed to the Mediterranean to search for the answers. On August 23, 1970, they recovered a sample. The sample consisted of pebbles of gypsum and fragments of volcanic rock. Not a single pebble was found that might have indicated that the pebbles came from the nearby continent. In the days following, samples of solid gypsum were repeatedly brought on deck as drilling operations penetrated the seafloor. Furthermore, the gypsum was found to possess peculiarities of composition and structure that suggested it had formed on desert flats. Sediment above and below the gypsum layer contained tiny marine fossils, indicating open-ocean conditions. As they drilled into the central and deepest part of the Mediterranean basin, the scientists took solid, shiny, crystalline salt from the core barrel. Interbedded with the salt were thin layers of what appeared to be windblown silt. 4．Which of the following can be inferred from paragraph 3 about the solid gypsum layer? ○It did not contain any marine fossil. ○It had formed in open-ocean conditions. ○It had once been soft, deep-sea mud. ○It contained sediment from nearby deserts. 第30篇的第四題這一題看到答案覺得有點莫名其妙不知道問題是不是少了個not ?? which of the following can "not" 第三段中文如下帶著這些清楚擺在他們面前的問題，科學家們登上Glomar Challenger號前往地中海尋找答案。 1970年8月23日，他們恢復了一個樣本。這個樣本由石膏鵝卵石和火山岩碎塊組成。周圍沒有鵝卵石被發現，這可能說明這些小石頭不來自附近的大陸。接下來的日子裡，隨著海底岩層穿透實驗的進行，石膏固體樣本被不斷地放在甲板上。而且，這些膏狀物的組成和結構特性表明它們形成於沙漠。在石膏層上下的沉積物中包含了微小的海洋生物化石，這說明了是開放性的海洋環境。當鑽到地中海盆地中心的最深處時，科學家們從鑽管中獲得了堅實的、光亮的結晶鹽。跟結晶鹽相互嵌在一起的薄層像是被風吹起的泥沙層。 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.112.4.191
