Phương pháp giải

Kiến thức: Mệnh đề quan hệ không xác định

Lời giải của GV Loigiaihay.com

- Dấu hiệu nhận biết mệnh đề quan hệ không xác định: có dấu phẩy 

which => dùng làm chủ ngữ, thay thế cho danh từ chỉ vật: ...N(thing), which + V1, V2

that => không dùng trong mệnh đề quan hệ không xác định

what = the thing that => what + S + V

it: nó

Sau chỗ trống là động từ “was” => cần một đại từ quan hệ làm chủ ngữ

The United Nations, which was established in 1945, has over 200 members.

Tạm dịch: Liên hợp quốc, cái mà được thành lập vào năm 1945, đã có hơn 200 thành viên.
