This excerise, says 'soudain' instead of 'soudainment'... can someone speak to this for me please :) Or point me to a lesson! Thank you.

And sudden -- instead of And suddenly.

Still unsure about when to use article “le” and days of the week. Could you elaborate more on this idea of specific context, maybe w an example or two? 

Shouldn't it be changions de voitures for "change cars" - i.e. plural form for cars? Isn't there a difference between 'change cars' and 'change our car' - i.e. the noun being singular or plural?

Why would it be "C'était un bâtard" not "Il était un bâtard?" The statement is specific. I asked my partner, who is a native French speaker, and he said both sounded correct/normal to him. He couldn't figure out why the latter is unacceptable, even viewing the rules provided. 

Of course I try to spend less time on social media, but let's not throw out the baby with the bathwater. Here is a channel I found, which is fun to listen to, quite easy to understand, and helps to improve how French your French sounds:

Can I say Qu'est instead of 

I think since 1990 and the contentious spelling reforms, there are now two acceptable ways to spell “onion” in French. I think the Academy even prefers “ognon” to be used over “oignon”. In the same way that you now allow “s’il vous plait” without the circumflex as well as “s’il vous plaît”, maybe you should add the new spelling of onion as an acceptable option?
