Chọn C                                 Câu đề bài: “Mặc dù sấm và sét được tạo ra cùng một lúc, sóng ánh sáng đi xa hơn___________, vì vậy chúng ta thấy sét trước khi chúng ta nghe thấy sấm ".

Đáp án C: than sound waves do

—» Đây là cách nói rút gọn của “than sound waves travel”: cấu trúc so sánh hơn kém:

S + V + trạng từ ngắn đuôi er/dài thêm more + than + S + V.

Đáp án A

Giải thích: Khi so sánh, vế sau than phải dùng đúng cấu trúc như về trước (ví dụ He drives faster than I drive/ He is taller than I am), tuy nhiên có thể tránh lặp bằng cách thay động từ bằng trợ động từ tương ứng, to be thì giữ nguyên.

Dịch nghĩa: Mặc dù sấm và chớp được tạo ra cùng một lúc, nhưng sóng ánh sáng đi nhanh hơn sóng âm thanh nên ta nhìn thấy chớp trước khi nghe thấy sấm.
