Clearly the nice and better is being used for the boyfriends (subject) and not is the verb, then why on earth are we using mieux here? It seems to be an error, feel free to correct me though.

How do you know whether to use "depuis" or "il y a" to express a period of time. These lessons have had "J'habite à Paris depuis cinq ans" and also "J'ai mangé il y a un heure"

How do you know whether or not an adjective goes before or after the noun? 

Shouldn’t the verb here be connaître ?

The lesson says:

Conjugations of APPARAÎTRE (to appear) in Le Passé

Composé (Indicatif) in French

j'/je

 suis apparu(e)

tu

 es apparu(e)

il / elle / on

 est apparu(e)(s)

nous

 sommes apparu(e)s

In the one question they use 'en': "Il s'en souvient. = He remembers it." I don't see anything in this lesson explaining when we would use en with this verb? 

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.
