In the question "On ________ passé par là?", should there not be an 's', in this particular case, at the end of passé?

In one of the writing exercises, I translated "I love my cousin Benjamin" to, "J'aime bien mon cousin Benjamin", but the system corrected this to "J'aime beaucoup mon cousin Benjamin". Why? It actually seems to me that "J'aime bien" is more appropriate than "J'aime beaucoup" (I like a lot).

"Comme des mots-clic" but " des hashtags en tant que"  Why not "comme des hashtags"?

Is teh below wrong?
Quand est-ce qu'on va arrivés ? 

Could this be elle va être?

Why does the first word have its final “e”? Is is agreeing with the feminine noun “fin”?

Also, is the first word best considered as an adjective or as a past participle in this sentence?
