The best way to clear up Basit’s confusion is: “The air around us is actually only 20 percent oxygen, so we need to take thousands of breaths each day to get enough oxygen!”
This response directly addresses Basit's misunderstanding that we breathe in 100 percent oxygen by explaining the actual composition of the air and emphasizing the importance of continuous breathing to obtain sufficient oxygen.
