My grandfather had his first job when he was just a little older than I am now. I love to listen to his stories about the different kinds of work he did when he was growing up. He worked in restaurants and factories. One summer he even had a job on a cattle ranch. Grandpa says he always
worked hard and did his best. He also developed the habit of being punctual."No matter what the job was," he says, "I always made sure to show
up on time."
What does the word punctual mean in the passage?
1. careful
O 2
curious
3. polite
4. prompt
