12. which of the following describes how don john operates in act i?

 I do not see a choice for answers, but Don John is not too thrilled at having to conform to Don Pedro's expectations.  He walks around, moping around, head hung low, and is not cheerful.    He also is very negative.  He thinks that if he cannot have something, then others should not have it too.  He hates Claudio for being well loved; he is jealous.  He wants to create problems for others.  If he can't be happy, then why should anyone else?  He resents Don Pedro, because he is successful.  He lies to people, and creates gossip and problems for others.  Shakespeare often used tragedy to explain a lot of his characters.  The fact that he is only a step-child -actually turns him into a villian. He cannot have what the first child can have, and therefore, he feels he can never amount to anything.  He really justs wants to be evil and mess over his brother any way that he can.  Evil dude.
