French language Q&A Forum

If heard that in spoken french the ne is often dropped, so would c´est pas be a correct way of saying it isn´t?

A sentence mentions-

La compagnie pour laquelle je travaille a les meilleurs résultats du secteur.The company for which I work has the best results in the industry.

I would like to ask whether “dans laquelle” is also acceptable ?

Also if a sentence is given-

L’automne est la saison .................... les feuilles jaunissent. 

I came up with the following options-

pendant laquelle/ dans laquelle/ en laquelle 

Which of the above is grammatically accurate?

Je vous remercierais pour votre réponse.

Someone to help me solving this? I need to answear today and i tried a lot of French dictionaries and didn't get this. 

Bonjour Madame, 

There is a line in this comprehension as - “Ça n’entraîne pas des frais très très importants.”

Should it not be ‘de’ ? I am taught that whenever negative comes, then indefinite article ‘des’ changes to ‘de’. Being a beginner, I may be incorrect . Please provide further clarification.

Bonne journée !

“Vous êtes vendeues “

I chose Grace and Tom speaking but my answer was wrong the correct one was Grace and Anna.Can anyone explain why since vous is to address both gender.Many thanks.
