French language Q&A Forum

In the listening exercises the following is used

"ils prennent leur rôle de grandes-parents très au sérieux". Why "très au sérieux" and not "très sérieux"?

Thank you

Not really a French question, but how do you type a dash to get a "your answer matched mine" in the writing exercises? Even if I write exactly the same as the model answer, if the phrase begins with a dash the computer doesn't credit me with getting it right. Is it something to do with the number of spaces before or after? Or is there a type of dash I'm not using? 

Frustrating as I challenge myself to get 3 or 4 "matches" per exercise, but this means half of my attempts have no chance....

  As in this sentence we are talking about Cecile(female), so why we use "anglais" instead of "anglaise"

I teach Spanish and French.  In the preterit Spanish, SABER (their equivalent of savoir) carries the idea of someone finding out a fact or knowing it for a short time.  Is this true in French in the passé composé?

In other words, does "j'ai su son nom" carry the idea "I found out his name"?  Or even "I knew his name; but forgot it"?

Bonjour,

Comment ça se fait que.... and Comment se fait-il que....

Are the above not interchangeable?  I keep getting marked wrong when I use the second one.

Merci, Julia

Tu n'as pas habité ici depuis longtemps.  I've studied and understood the rule about using the 'passé composé but I can't see where my mistake is. Help!
