This material, along with reinforced concrete provided the necessary components to feasibly construct high-rise skyscrapers.
[A] Skyscrapers, with their massive size and weight, were unthinkable until construction technology began to incorporate metal frames to distribute the weight that walls alone could not withstand. [B] It was the growing accessibility of steel—a relatively light material with a very high tensile strength—in the 1860s that revolutionized building construction, providing powerful frames capable of supporting the weight of taller structures. [C] With the means to meet these structural requirements, architects and engineers began to design and erect stable, towering buildings. [D]
왜 정답이 B인가요?
저는 C로 골랐는데...
steel material에 관한 얘기가나오니까 그다음에 이 material이~로 설명되어지는게
자연스러운 흐름아닌가요?
답변부탁드립니다 ㅜㅜ
