Đáp án đúng: D
Đáp án D
Theo bài đọc, tại sao thủy tinh dễ tạo hình dáng cụ thể hơn kim loại?
Dẫn chứng: “Unlike metals that flow or “freeze” at specific temperatures glass progressively softens as the temperature rises.... allows the glass to be manipulated into various forms.” (Không giống kim loại chảy và “đóng băng” ở nhiệt độ cụ thể, thủy tinh dần mềm ra khi nhiệt độ tăng... cho phép thủy tinh tạo thành nhiều hình dạng.)
