What is the meaning and use of 'que'?

I continue to get this wrong so I know I must be missing a basic rule:

The sentences :

-Quant aux poses de yoga, leurs innombrables avantages……..

-Finalement, n’oublions pas le côté méditatif du yoga

Why de yoga in the first but du yoga in the second?

I'm wondering why in the sentence: "...during that period, I did not have to take the train.", the imperfect of devoir is used instead of the perfect tense?  Since it is a specific and closed period of time (three weeks), doesn't that mean it's not an ongoing action?  Thanks.  

I think I may need a bigger dictionary! I am struggling to find the appropriate word.  For example:

Le sol versus le plancher

imparable versus imbattable versus incomparable versus inégalable

évident versus manifeste. 

Also the suggested answer "je vais faire une machine" seems to translate as "I'm going to make a machine"

Help !!

Is the S silent for both?  The pronounciation seems to differ with the speakers/examples.  The woman speaking the following does not pronounce the S:  Les ordinateurs deviennent de moins en moins chers.  But the woman speaking the following sentence does:  Nous y allons de moins en moins souvent.

Salut -

In the kwiziq glossary entry for Verbes aux deux auxiliares, it mentions that demeurer follows "the reverse pattern" to the transitive/intransitive rule.

I have used that as my rule of thumb for a while now, and it was always confusing to me (as a verbe d'état, it is intransitive, yet takes auxiliary « être », so that note didn't feel right).

I just found the comments and explanations here on this page, and all is now clear - thank you Aurélie and other contributors for the information you have shared here!

It might be worth correcting that glossary page entry, too, in case others stumble across it in the future.

In the lesson, for 91, it says: “Note: NO et, just like 81.” Do you mean just like 71, which, like 91, includes onze?

if there is a noun at the begining of the sentence we have two ways to ask a question ;

est-ce que henry a un sac?

henry a-t-il un sac
can we use the "a" at the begining of the question word?
for example A henry un sac or  "ont les femmes des crayons? does it work? 

I wish your helps
Thank you so much
