To determine the correct sequence of events, we can think logically about the order in which they likely occurred.
- The boy came home. - This is likely the first event because he needs to be home to do anything else.
- He read the note on the refrigerator. - After arriving home, he would typically look at or read any notes left for him.
- The boy went out to the yard. - After reading the note, he might decide to go outside.
- He mowed the lawn. - Finally, after going to the yard, he would carry out the task of mowing the lawn.
So, the first event in the sequence is: The boy came home.
