I believe the correct answer is sentences 2,5 and 6.
Complex sentences are composed of one independent
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.
Dependent clause is a group of words that contains a subject and a predicate. Although this contains a subject and a predicate, the thought is not complete and can not stand on its own. For example, "since he did not pay the rent". In this instance, the clause has a subject and a verb but shows no thought or meaning.
An independent clause is a group of words comprised of a subject and a predicate and expresses a thought thus, called independent. For instance, "I arrived early", "She sings."
