How long has Hannah been working as a solicitor?

The correct answer indicates that Hannah has been working as a solicitor for three years. This duration suggests a level of experience that might involve familiarity with the legal system, established relationships with clients, and a progression in her legal skills and understanding of complex cases.

In the context of professional development, three years can be a significant time frame for practical experience in a competitive field like law, where learning often extends beyond formal education into the nuances of practice. Focusing on this timeframe allows us to understand the potential level of competence and expertise that might accompany her current position, indicating that she likely has encountered various legal situations and gained insight into case management and client relations.

Other durations, such as two years, four years, or five years, do not reflect the outlined level of experience that corresponds with the breadth of skills typically developed over three years in the legal profession. Therefore, identifying three years as the answer supports the inference of her growing proficiency as a solicitor over this specific period.
