Hướng dẫn giải

Đáp án đúng: B

Dịch nghĩa: Mike đã trở thành một người cha. Anh cảm thấy trách nhiệm nặng nề đối với cha mẹ mình.

= B. Chỉ sau khi trở thành bố, Mike mới cảm thấy trách nhiệm mạnh mẽ với cha mẹ mình.

A. Sai: Câu điều kiện loại 2 (giả định hiện tại) – không phù hợp.

B. Đúng: Only after + had + PII, did + S + V → nhấn mạnh "chỉ sau khi... mới..." (thời gian quá khứ).

C. Sai: Câu điều kiện loại 3 (giả định quá khứ) – không hợp.

D. Sai: Đảo ngược logic (nghĩa thành chỉ sau khi có trách nhiệm thì mới làm bố).

Chọn B.
