Read the passage, then answer: Which sentence best summarizes the passage?

A young engineer named Lila loved solving practical problems. In her city, many people wasted water without noticing. Leaky pipes dripped for days, and sprinklers ran during rain. Lila believed that small changes could save a great amount.

She joined a school science fair with a simple idea. She built a low cost sensor that listened for steady dripping sounds. When it detected a leak, it sent a message to a phone app. The app also suggested easy steps, like tightening a valve.

Lila tested her device in her apartment building with permission. Within two weeks, the manager fixed three hidden leaks. The water bill dropped, and neighbors became more careful. Some even reported leaks they had ignored before.

Lila did not claim her invention was perfect. Loud music sometimes confused the sensor, and thick walls reduced its accuracy. Still, her project showed that careful observation and teamwork can protect shared resources.
