Throughout the Mesozoic Era, pterosaurs dominated prehistoric skies as the first vertebrates known to have evolved powered flight. Unlike modern birds, whose wings are formed primarily by feathers attached along the forelimb, pterosaurs possessed a membranous wing consisting of skin, muscle, and tough structural fibers. ----. This anatomical architecture allowed them to adjust wing camber and tension dynamically during turbulent atmospheric glides.
- A)Fossil evidence indicates that marine reptiles like plesiosaurs never developed airborne capabilities
- B)Most paleontologists agree that bird-like feathers first emerged among predatory theropod dinosaurs
- C)This delicate yet resilient membrane was anchored to an extraordinarily elongated fourth finger on each hand
- D)Consequently, bird skeletons are significantly denser than those of airborne reptile species
- E)Several late Cretaceous species achieved flight solely by leaping from seaside cliffs into thermal updrafts

Doğru cevap: C) This delicate yet resilient membrane was anchored to an extraordinarily elongated fourth finger on each hand
Çözüm: Önceki cümlede bahsedilen kanat zarı ("membranous wing consisting of skin...") ve sonraki cümlede geçen "This anatomical architecture..." ifadesi, kanat zarının uzamış dördüncü parmağa tutunduğunu anlatan C seçeneğiyle kusursuz birleşir.
