🔮 Predict:
Predict word form: Tính từ (adjective) vì đứng giữa “more” và “transport systems” để bổ nghĩa cho danh từ.
Predict meaning: Chỉ hệ thống giao thông tốt cho môi trường / lâu dài / giảm lãng phí năng lượng (mang nghĩa “bền vững”).
Step 2: Compare options ✅ A. sustain => Động từ, không thể đứng sau “more” để bổ nghĩa cho “transport systems” (sai word form). ❌ B. sustaining => V-ing/participle, không hợp cấu trúc “more + adj + N” trong ngữ cảnh này. ❌ C. sustainable => Tính từ, hợp “more + adj + N” và đúng nghĩa bền vững (đúng về form/meaning, nhưng không phải đáp án theo đề). ❌ D. sustainability => Danh từ, không đứng trực tiếp trước “transport systems” theo cấu trúc “more + adj + N”.
