Which of these is a simple sentence and why? 1) Karen and David arrived at the airport at 3:35 p.pm and took a taxi to their hotel. 2) I went to the airport, but I was too late to meet them. 3) When I realized I was too late, I called David's cell phone and made arrangements to meet them in town. 4) I got to the airport late because the traffic was so terrible.
