PSAT Reading & Writing Question of the Day

From "Letting Rivers Breathe" by Sofia Al-Khalil (2020). We straightened urban rivers to make them safer and more efficient, or so the story goes. Yet cities that have let channels meander again, widened floodplains, and planted native reeds report fewer catastrophic floods and a surprising return of wildlife. Concrete walls can fail all at once; a living edge bends and absorbs. Still, ripping out every slab would be reckless where neighborhoods hug the banks. The better path is selective: remove hard barriers where room allows, carve terraces where it does not, and weave in crossings that keep streets connected. If we want rivers to protect us, we must first allow them to act like rivers—and design our cities with that freedom in mind.
