clause and at least one dependent clause. The examples from "The Enigma
Machine” which are complex sentences are:
<span>2. </span>For
example, Bletchley Park was crucial in the Battle of the Atlantic, which lasted
six years.
5. This
was provided in a codebook, which was a monthly list of daily keys distributed
to various networks in the German military.
6. Since
the Enigma machine could encrypt text into over 150 trillion possible
combinations, Germans were convinced the codes were not decipherable.

One evening, me and my friend Jack were playing outside. We decided a friendly game of football would be fun. We were just tossing and throwing the ball to each other, like normal boys would do.
All of a sudden, Jack started crying. I went up to him in desperation, as I noticed that he had broken his arm! He ran into the neighbor's car, and he hit his arm so hard on the side mirror, that it broke! We had to admit him into the hospital!
After a long time in the emergency room, Jack was free to go to his house. This had to be the scariest moment for me. I'm going to be taking a little break from football. I hope this never happens again...
