Phương án B dùng từ nối when nhưng vẫn sai vì nếu ghép phương án B vào chỗ trống thì tự nhiên xuất hiện be needed (be không được chia theo thì) sau chủ ngữ hydroelectric power → sai ngữ pháp
Phương án C cũng sai vì nêu ghép C vào chỗ trống thì be không được chia theo thì và nếu nối 2 mệnh đề thì phải cần từ nối → sai ngữ pháp
