问题 By making some very simple changes at home, old people ______.
Last Steps on stairs may become a high-risk accident area if they are ______.
选项 A、not painted in a different color
B、not marked with bright tapes
C、fixed with grab bars
D、very brightly lit
答案B
解析 本题为细节推断题。由题干last steps 和high-risk accident area定位到文章第二段第三句“Applying bright tapes and using bright light in these areas would make these spots easier to see.”(在这样的地方用亮色的带子和明亮的灯照明，会使这些地方更容易被看清。)可推出：如果不用亮带子和灯，最后几个台阶还是事故高发的地方。A项颜色问题文中未提；C项安装把手是在浴室采取的措施；D项强光照明，最后几个台阶就不是事故高发地带了。因此，答案为B。
