Answer:
Esther is ninety years old, but she still shops for her own groceries every morning. When Esther was younger, she would head to Main Street and stop at the butcher shop for meat, the bakery for bread, and the farmer s market for fruits and vegetables. Now, she goes to a supermarket, where she can shop for all of those items under one roof and spend much less time buying food for the day. The convenience that Esther enjoys is called <u>contact efficiency.</u>
