I thought it is depuis...je suis (not past).

Or is it a difference between:

Since then, I have been following her career

Vs

I have since been following her career.

Franchir vs croiser always confuses me. Please explain

In the sentence "il suffit d’observer ce que font les autres et les imiter," why have the verb (font) and the subject (les autres) swapped places? Shouldn't it be "il suffit d’observer ce que les autres font et les imiter"?

The sentence is taken from this text: "https://www.lawlessfrench.com/listening/bise-a-la-francaise/"

Thank you in advance. 

Why is there no preposition "de" after the verb "descend" in the phrase: "Elle descend les escaliers" ?

Why is "il lui faut de l'aide" - he / she needs some help and "il te faut de l'aide"  - you must help? I am getting very confused with this expression!

«Depuis, impossible de trouver une position qui puisse soulager la douleur. Je ne peux ni dormir, ni m'allonger, ni me déplacer correctement.»  Can the first sentence really stand on its own? It would make more sense to me if this were all one long sentence with a comma after “douleur”. Am I wrong?

Do the singular names that refer to groups take the same conjugation like (il/elle) or like (ils/elles) 

Ex: is it la famille est or la famille sont ?
