　　Also in Sweden,/there was an experiment to encourage people/to throw their trash away properly.// A loudspeaker and a sensor/were placed inside an ordinary trash can.// When you dropped something into the can,/it made a long falling sound/as if the bottom was deep underground.// People loved it/and because of the little nudge,/the streets became much cleaner.//
　　The Indian city of Mumbai/is known as “the honking capital of the world.”// Mumbai drivers are always honking.// They even honk at traffic lights.// To encourage better manners,/police have come up with/the “Honk More, Wait More” system.// The system resets the red signal/every time the sound of horns/goes above 85 decibels:/a little nudge to be patient.//
　　We can also find examples of nudges/in schools.// Many schools in the U.S./use a nudge in their cafeterias/to encourage healthy choices.// Research shows/that if you put fruit in an attractive bowl/at the start of the line,/more students make the healthy choice:/they choose fruit.//
