Is there a deal for family members who want to get Premium plans at the same time? 

I understand that, as a general rule, in French, we add definite articles before a country’s name. E.g.: J’aime la France. However, I also understand that if the country’s name comes after “de”, and the country is feminine, then, we omit the definite article. E.g.: Je viens de France. However, I am terribly confused by the phrase “Au service de la France” - why is there a definite article after “de” in this phrase?

Then why is "nous nous sommes brossé" correct?  shouldn't it be "brosses"????

My reflexive response to translation of 'We opened the windows out of fear there might be a gas leak.' was 'Nous avons ouvert les fenêtres de peur qu'il ne puisse y avoir une fuite de gaz.' given that there is a sense of conditional pouvoir in the translation ('there could be or 'might be', rather than the softer 'we're not sure' sense of avoir in the subjunctive. Any thoughts?
