Nous avons attendu pendant qu'il changeait le pneu.  

Why is 'que' needed? The 2nd clause uses the imparfait. So, except for le present, can other tenses follow 'pendant que' ?

I can't seem to differentiate between the cojugate form of etre and avoir when used with the first person Je. Par exemple:
Je suis grand.
versus 
J'ai cinq ans.

They both seem to mean "I am" in the above sentence.

hello, i am trying to understand this lesson but how the topic is represented is very confusing and tedious to me. is there a way to edit the lesson and put it in a table with a column of all the de.. a and du..au and their explanations. i am so discouraged :(

Quel est le meilleur aspirateur? is a usage  ( non action )

where as Laquelle de ces bouilloires marche le mieux?  uses a verb action ?  i.e the kettle works  ?
