2. Taking into consideration the main features of Charles Dickens' style, you can notice the use of contrasts, such as "The master was a fat,  healthy man; but he turned very pale" and "festive composition". What's more, you come across the use of hyperboles like "as if they could have devoured the very bricks of which it was composed" and "he was afraid he might some night happen to eat the boy we slept next to him" and the one of repetitions, such as "that boy will be hung" and "for more".

3.The author sympathizes with the boys: in a way, he glorifies the boy's will to rebel against the master.

5. The third person omniscient narrator is characterized by the following features: he knows all about his characters and their external and inner lives; he describes the events from a high perspective; he makes his characters move like puppeteer with his puppets.

6. In truth, Dickens' serious aim in telling this episode consists of portraying the poorness among English society in 19^th century and the terrible conditions the high number of its orphans was condemned to bear without chances to react.
