French language Q&A Forum

Hello, I answered a questions that asked what the "Low Countries" were as "Les Pays-bas" which I learned in my French class, were the combination of The Netherlands, Luxembourg and Belgium. But the correct answer was The Netherlands event though the verb was "ont" and not "a" and the Netherlands is a single country. Could you tell me what the actual Low Countries would be in French?

In "Je vais à Paris" the s in vais is not pronnounced, but I had also undestood that when the word ends in a consonant, and the next word is a vocal, you pronounce the last letter to kinda carry the "flow", I forgot what the proper name for the rule was.
