1. B (take .... time: tốn/mất ... thời gian)

2. Minh thinks (that) skating is more interesting than playing board games. 

(So sánh hơn: S1 + tobe + more + tính từ dài + than + S2; interesting là tính từ có 3 âm tiết => tính từ dài)

3. How much cooking oil do you need?

(How much + N không đếm được + trợ đt + S + V_nguyên thể?: Bao nhiêu...?)
