請依下文回答第 36 題至第 40 題： Throughout the history of life, there have been many major upheavals in which whole groups of animals were replaced by others. Perhaps the most famous was the replacement of dinosaurs by mammals about 65 million years ago. Another major change occurred roughly 150 million years earlier, when dinosaurs assumed dominance that had been held for about 80 million years by mammal-like reptiles. What triggered these great upheavals? Scientific thinking about the factors responsible for these replacements has itself changed with significant shifts. At times, scientists suggested that mammals caused dinosaur extinction by eating eggs or competing for the same food resources. However, most researchers now agree that mammals played at most a minor role—since both groups coexisted for millions of years—and that environmental change was primarily responsible. Mammals apparently remained small and inconspicuous in the Mesozoic undergrowth for some 150 million years, until the extinction of dinosaurs gave them the opportunity to radiate into available niches.

請仔細觀察第二段的第一句話，作者提到關於這些大變遷的「科學思考」（Scientific thinking）經歷了什麼樣的過程？如果一段論述在發展中發生了「顯著的位移或轉變」(significant shifts)，這暗示了這些論點在時間長河中，其內容是一致的，還是有所變動呢？

勉強及格，但值得一提。
- 觀念驗證：恭喜你，你終於看見了第二段開頭那句『Scientific thinking... has itself changed with significant shifts』。是的，『significant shifts』（重大的轉變）就這麼恰巧地對應到選項 (A) 的『considerably different』（相當不同）。這說明了什麼？哦，原來連科學界的看法也沒那麼死板，會『轉變』代表它以前和現在『不同』，這很難理解嗎？
- 難度點評：此題難度是 Medium。其鑑別度在於，你是否具備基本的『同義轉換』（Paraphrasing）能力。能把『變動』解讀成『差異』，說明你對文字的敏感度還沒完全陣亡。下次看到這種題，希望你能更快地抓住重點，別讓這些『轉變』考倒你。
