Pierre,fait-il encore le devoir

Change the negative expression 

my goal is conversational french. I'm happy to know that passe simple exists, but I dont want to spend time on it. Is it possible to ignore it ?

My question was asked below, but the answers provided did not address my confusion. 
One example given in this lesson is "Si nous l'avions choisi, nous l'aurions regretté".

A previous lesson on 'if-then" sentences (Imperfect usage - hypothesis | French Grammar | Progress with Lawless French) says the following: 
 "You can never use Le Passé Composé nor other past tenses in this context."
I took this to mean that all if-then sentences must use an "imparfait + conditionel présent" form. 

But here we are using the plus-que-parfait and the conditional passé in an if-then sentence. There is no mention of the plus-que-parfait + conditional passé form in the lesson linked to above.

Can you please clarify the rules around using plus-que-parfait + conditional present in 'if-then' sentences? 

Thanks.

She went to France for vacations, she generally rents a house in the country. Then she goes to the village to buy some fruits and vegetables, and to talk with some neighbors. Then she passes by a beakey and she buys a  warm baguette and a croissant for breakfast. In the afternoon she takes a walk in the country to explore the region. Sometimes she likes to have a fruit tart and she invites a few friends over for a snack. These are very relaxing vacations.

For example, if we're picking out paint colors and I said "Do you like the purple?" I'm talking about a specific thing, would that not be Il est...?

Edit: And it just came up again, this time as "Tu aimes l'école?"  That again is lacking context, are we walking about a specific school or school in general?  

How do you know if a word requires avoir or être in passé composé like for eg finir how do we know if it requires avoir or être when you see the word 

 nous sommes brossé is incorrect, should be nous sommes brossés
