How we answer in Franch

Why is it when I asked to be 'kwizzed' on just this lesson, included in the quizz are questions from all of my 'recommended lessons'?  How do I go about finding a quiz with just 'question word' questions in order to give me extra practise with question words?

Thanks for your help........Thirza

Hello.i didnt undrstand why he didn't use -de km - for the first sentence below

How far is it from here to your home -il y a combien d'ici a chez toi 

How far is it from Paris to Lyon -il y a combien de km de Paris a Lyon 

I translated "how many times" (I've got lost) as "combien de fois" rather than "le nombre de fois".  This was not listed as an alternative, but according to my Reverso app they are both acceptable in this context.  When would you use one rather than the other?
