Question

Choose the sentence with correct structure


I first went to the gym then I had breakfast.


I first went to the gym, then I had breakfast.

Answer 1

"I first went to the gym, then I had breakfast."

This correctly separates the two independent clauses. (For more formal writing you can also use a period or semicolon: "I first went to the gym. Then I had breakfast." or "I first went to the gym; then I had breakfast.")
