And these are the correct answers:
- lingua franca
- national education system
- extensive transportation network
Step-by-step explanation:
The lingua franca was a key aspect that led to the unification of France. Before the French Revolution, France still had remnants of the Feudal Society it was for centuries, and this meant that many languages are spoken accross France, each with many dialects. The central administration decided to impose the French language that was spoken in and around Paris to the rest of the country, supressing other languages such as Occitan and Breton.
The national education system was also important because it allowed the teaching of a common French language, a common history, and a common culture.
And the extensive transportation network, particularly the railways, allowed the exchange of ideas, goods, and services, something that helped unify the country.
