Answer:
Well, this is going to be a long answer! I hope I helped, please correct me if I'm wrong!
1. I believe he took Caesar's wife and Cinna’s daughter, in exchange of his life, since research showed that Young Julius Caesar was proscribed for no reason other than he refused to divorce his wife. (I'm not very sure about this)
2. He never married her because Rome, after all, did not recognize plural marriage, and at that time, Caesar was still married to Calpurnia.
3. Caesar focused on economic changes, like improved land and waterways. His political reforms focused on creating physical structures, rebuilding cities and temples, and improving the Senate, The main ruling body in Rome. (I'm sorry about this one, I'm not very sure which one was most important)
4. The senators assassinated Caesar because they feared his unprecedented concentration of power during his dictatorship was undermining the Roman Republic, and presented the deed as an act of tyrannicide.
5. The death of Julius Caesar ultimately had the opposite impact of what his assassins hoped. Much of the Roman public hated the senators for the assassination, and a series of civil wars ensued.
