A few sentences. What are the mistakes ? I have just read an article from the website « lemonde.fr ». This article deals with the public transport in Ile-de-France, it means Paris and a large area around that is a crowded area. The main purpose of this article is that the Cour des Comptes in France, advocates fares’ increase. The reason of this recommendation is that the state of the public transport is not good due to a lack of investment.
