The correct option is this one - A complex sentence has one independent clause (a whole sentence) and one dependent clause (a partial sentence). A dependent clause is a type of a clause which cannot stand on its own, but rather has to be included in a bigger sentence in order to make sense. Here, the dependent clause is <em>Even though April began eating more fruits and vegetables. </em>As you can see, this clause sounds incomplete, which is why it is joined with the independent clause <em>she decided to continue drinking soft drinks </em>in order to make sense.
The topic of the passage is a duel between Laertes and Hamlet. Claudius, who wishes to get rid of Hamlet, wants him to fight a duel with Laertes, pretending he bets Hamlet can win. Laertes, on the other hand, is eager to revenge his father's death, Polonius, who has been accidentally killed by Hamlet.
