French language Q&A Forum

I was asked in a C1 test to complete the sentence, " Après....., ils se sont perdus". After leaving, they got lost.

I wrote, "Après avoir quitté, ils se sont perdus". It was marked incorrect. Why?

Various authorities suggest that one uses voir for the cinema and regarder for the tv. Could you clarify? After I watched the film, after I saw the film... ??

In this example, the English translation seems like the present tense ... "is sitting".  But "assis" is the past participle for the verb s'asseoir / to sit.  How would this be described gramatically, or why not use l'imparfait or present tense? 

Also is this grammatical usage of a past participle "seated", unique to the verb s'asseoir?    Thank you.

Here is the example from above: 

Mon frère est assis dans la rangée devant moi.My brother is sitting in the row before me.

question was write nine thirty so i put du matin and it was marked wrong, just nine thirty was correct. thought we were meant to specify. when i used 24 hour clock i get marked wrong.

what are the rules as im getting so confused.

This was asked 4 years ago and never answered.
"This apple is good. Yes, it is good."  is the stated English translation.
Had the English translation been "Yes, THEY are good", then "c'est bon" may be correct.
But, as stated, since IT is specific and refers to THIS APPLE, the French should be "Oui, elle est bonne."
