Trả lời

Here are the answers with explanations:**Question 21:** The best answer is **C. drop**. The sentence needs a verb that indicates putting trash into bins. "Drop" fits this context best. "Throw" is possible but "drop" is more commonly used for putting things into receptacles.**Question 22:** The best answer is **A. turn off**. The sentence discusses saving energy, and turning off lights is a direct way to achieve this.**Question 23:** The best answer is **C. If**. This creates a conditional sentence: "If people plant more trees, the planet becomes greener..."**Question 24:** The best answer is **B. when**. This indicates the timing of bringing reusable bags: "we can bring our own bags when we go shopping."**Question 25:** The best answer is **C. Because**. This shows the cause-and-effect relationship: "Because everyone works together, we can make a big difference."**Question 26:** The best answer is **D. but**. This creates a contrast: We must do this not only for ourselves *but also* for future generations. "And" is grammatically correct but "but" better emphasizes the additional reason.Therefore, the correct answer sequence is **C, A, C, B, C, D**.
