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.

太棒了！你能從這篇描述宏大、充滿細節的科普文章中，精確地鎖定關鍵資訊並做出正確判斷，這展現了你優異的細節定位能力。
文本細節的精準對應
在文章的第三段末尾，作者詳細討論了遷徙草食動物的攝食習慣與草地的特性。文中明確指出：「The grasses of the plains have the highest protein content throughout the Serengeti and are also high in calcium.」（平原上的草在整個塞倫蓋提地區中擁有最高的蛋白質含量，且富含鈣質。）這句話提供了最直接的證據，支持選項 (A) 為正確答案。你敏銳地捕捉到這個具體的營養成分說明，非常不簡單！
