French language Q&A Forum

In the correction list offered, I was surprised to see "Le dimanche".

Is there a particular reason why this is correct here since the text implies only the one Sunday, not all Sundays?

The question was:

Je décris les gens et je ________ parfaitement.

I describe people and I describe you perfectly.

Since the English "you" could be translated as either "tu" or "vous", the following two answers should be correct:

te décris

vous décrivez

I wrote the second one but was marked as incorrect.

He has a lot of powerful friends. 

Il a beaucoup d'amis puissants. 

Is it correct to place puissant after the noun in this sentence? In which case puissant will precede noun?

Been looking at this for a long time. Conclusion is if you want to write a sentence using a/the/my , Or making a general opinion then use c'est. Otherwise use I'll/Elle est to make a specific opinion towards something/someone if there is no a/the/my in the sentence? 

Hello - I do not understand why Cette année is used, and not Cet an. We are not referring to a whole period, rather to a specific event at the end of a year.
