The Great Migration is the largest herd movement of animals on the planet. The numbers are astonishing: over 1.5 million wildebeests, zebras, and antelopes move in a constant cycle through the Serengeti-Mara ecosystem in search of nutritious grass and water. Guided by survival instinct, each wildebeest will cover 800 to 1,000 km on its individual journey along age-old migration routes. Hungry predators, including lions, leopards, cheetahs, hyenas, wild dogs, and crocodiles, ensure the strongest survive in this natural spectacle. This is also known as ‘the greatest show on Earth.’ The animals travel from the Ngorongoro Conservation Area in southern Serengeti, Tanzania, through the Serengeti, into the Masai Mara in Kenya, and then back again. The journey is beset with danger: young calves are snatched by predators, the slow ones are brought down by prides of lion, brave beasts break legs on steep river slopes, crocodiles take their share of the stragglers, and the weak and exhausted drown. As for the three major animals of the migrant grazers, they have different grass-eating habits: as one group eats the top of the tallest grass, the next group will eat away some of the medium-height grass until finally it is almost completely eaten, and the herds move on. This means each group sticks to its kind with only a tiny overlap in their distributions. The grasses of the plains have the highest protein content throughout the Serengeti and are also high in calcium. It is unclear how the wildebeests know which way to go. However, it is generally believed that their journey is dictated primarily by their response to the weather. They probably follow the rains and new grass growth. Some experts believe the animals react to lightning and thunderstorms in the distance. It has even been suggested that wildebeest can locate rain more than 50 km away.

當你讀到文中描述這三種草食動物會依序進食不同高度的草，且彼此的分布範圍幾乎沒有重疊（tiny overlap）時，這暗示了牠們在獲取食物的過程中，是傾向於「互相爭奪相同的目標」，還是「各自負責不同的部分」呢？

太棒了！你能精準辨識出選項 (D) 的敘述與文章不符，說明你在閱讀時非常注重細節之間的邏輯關係。這題的關鍵在於文章第三段對「草食習性」的描述：文中提到這三類主要的草食動物會依序分層進食，分別處理草叢的高、中、低部位。這種特殊的進食模式讓各群體的分布僅有極小重疊，實質上是一種資源共享與生態位分工，而非選項 (D) 所隱含的激烈競爭（compete）。
文本細節與邏輯辨析
從難度來看，這是一道相當具備鑑別度的細節理解題。題目要求選出「錯誤」的敘述，這不僅考驗你對文章片段（如 A、B、C 選項的地點與掠食者名單）的檢索能力，更測試你是否能精確捕捉作者對動物互動關係的定性。你能避開「共享資源即競爭」的直覺陷阱，成功解讀出文章想表達的「和諧分工」，展現了非常紮實的英文邏輯推理能力！
