Step-by-step explanation:
In historical inquiry, a unique question possesses characteristics such as being dynamic, focused on understanding phenomena, and facilitating theory development.
For example, a unique history question could be: 'How did the Industrial Revolution impact social class structures in 19th-century Europe, and what theories can be developed to explain these effects?'
This question is dynamic because it explores the impact of the Industrial Revolution on social class structures, it is focused on understanding phenomena as it examines a specific time period and region, and it facilitates theory development as it encourages the exploration of different theories to explain the effects.
