Birds have evolved many physical attributes that contribute to their flying ability. Wings are important, but adjustable tails, large hearts and light bones play critical roles
To fly, birds, like airplanes, move air across their wings. Wings are designed so that air above the wings is forced to move faster than air below the wing. This creates higher pressure under the wings, called lift, which pushes the bird up. Different wing types evolved for different ways of flying. Prolonged flight requires long wings and an ability to soar. Other birds need superior maneuverability. Finches and sparrows have short, broad wings. Faster birds, like hawks have built - in spoilers that reduce turbulence while flying. This allows a steeper angle of attack without stalling.
Tails have evolved for specialized use. The tail acts like a rudder helping birds steer. Birds brake by spreading out their tails as they land. This adaptation allows them to make sudden, controlled stops in essential skill, since most birds need to land on individual branches or on prey.
Flight takes muscle strength. If body builders had wings, they still could not flap hard enough to leave the ground. Birds have large, specialized hearts that beat much faster than the human heart and provide the necessary oxygen to the muscles. The breast muscle accounts for 15 percent of the bird’s body weight. On pigeons, it accounts for a third of their total body weight. Birds carry no excess baggage, they have hollow feathers and hollow bones with struts inside to maintain strength, like cross beams in a bridge. Birds fly to find a prey, escape predators, and attract mates-in other words, to survive
What does the author imply about the body builders having wings?

Chắc chắn chỉ có một đáp án được thông tin trong bài hỗ trợ, các đáp án còn lại đều sai hoặc không có thông tin trong bài. Lưu ý phải tìm thông tin dựa vào từ khóa, và không dùng kiến thức bản thân để trả lời loại câu hỏi này. Trích thông tin trong bài: “If body builders had wings, they still could not flap hard enough to leave the ground. Birds have large, specialized hearts that beat much faster than the human heart and provide the necessary oxygen to the muscles.”
Tạm dịch: Nếu những người tập thể hình có cánh, họ cũng không thể đập cánh đủ mạnh để rời bay lên khỏi mặt đất. Chim có trái tim lớn và chuyên biệt, có thể đập nhanh hơn tim người rất nhiều và cung cấp đủ lượng ô-xi cần thiết cho các cơ bắp”.
Vậy, dù những người tập thể hình có cánh, trái tim của họ vẫn không đủ lớn và bơm đủ máu đến các cơ bắp như tim của các loài chim.
Vì vậy, đáp án C là đáp án đúng
