One of the questions that was not numbered said, What happens to the paperweight and how is that important. When Winston was arrested the paper weight was smashed by one of the thought police. The paper weight represented his life and hit hideout. When they were arrested his whole world was crashing down and disappearing, just like when the weight was smashed. The paperweight could have also symbolized Winston's struggle to find out about the past and to over throw the party, the paper weight was smashed when he got arrested because his struggle was over and he couldn't do anything anymore.
Since he is in the custody of the thought police, he is probable not going to be able to find out anything about life of the past. I think that he will probably confess about everything when they start torturing him. He might actually get to live maybe if he follows what they say and cooperate
