Voilà deux petites cartes que j'avais achetées.

We do not accord in case of avoir verb as opposed to être in passé composé, but in Plus-que-parfait why have we accorded the 'acheter' verb when with avoir? And does the same happen in case of être as well (in Plus-que-parfait?)

During the exercise we see “ognon” instead of “oignon”, although this mistake is not present in the consolidated block of text at the end of the exercise. Here’s a copy/paste of the line during the exercise: “et mélangez-la avec l'ognon et l'ail finement hachés”

Est-ce la phrase  "Dans la serre, il y a plus de sept-cent papillons exotiques" correcte ?   on n'écrit pas sept-cents ?

Can anybody help me convert a French verb into a French noun? Is there any particular rule or grammatical tips or tricks that I can change a french verb into a french noun? Please help me. 

Are any of these options correct?

1) Savez-vous comment dire cela en anglais?  (Translator option)

2)Comment savez-vous dire cela en anglais?

3)Vous savez dire ça en anglais?

Translate this please: "Celui qui a santé est riche sans le savoir."

The speaker sounds like he is pronouncing the 't' in 'ecart', which should be silent. It almost sounds as if he is saying: "Ils ont cinq ans d'equatre".

When I listened to the word "ecart" in the Collins online dictionary it had the correct pronunciation with the 't' being silent.

Otherwise, I enjoyed this exercise and learned a new word: "ecart".  And, now, I don't think I will easily forget it either!

Tu nous vas mettre en retard ….. why can’t we say tu nous vas faire en retard?

Why is it "Bien qu'il soit actuellement l'astronaute français le plus célèbre...", and not "Bien que ce soit actuellement l'astronaute français le plus célèbre..." ? I thought that you have to use "c'est" (and not "il est") with a noun that has an article and an adjective.
