Answer:
3. Indeed, to this quick-witted youth, the whole noble science of the law was contained in a nutshell.
Step-by-step explanation:
Verbal irony is when someone says one thing but he meant just the opposite of that thing. It is a writer's way of being sarcastic about the situation in his own way. Here too in "Bartleby, the Scrivener", the passage is talking of Gingernut, who is the office boy so named by the others as he is often sent to get ginger nut for them. It is ironic in the sense that for this errand boy, the law isn't much, just about full in a nutshell. To him, there isn't much to be done in the lawyer's office in contrast to the actual need to rewrite and copy the many paper works that needs to be actually done by the other workers, the scriveners.
