Hi

There are three phrases which the lesson translates into the same expression “What is a pen?”

Qu’est-ce que / Qu’est-ce qu’un stylo ?

Qu’est-ce que c’est / Qu’est-ce que c’est un stylo ?

Qu’est-ce que c’est que / Qu’est-ce que c’est qu’un stylo ?

What is the difference between the 3 questions?   When should each one be used?

Thanks

Could someone explain how I can create sentences with this statement below? 

In French you can also use the expression faire plaisir à [quelqu'un] to say to please [someone], to make [someone] happy

Thank you very much !

I had "Vas te coucher" as my translation of "Go to bed".  It is listed in the example as a correct translation.  Can you tell me why it was marked as incorrect please.
