Hi Kwiziq, I think there is a bug with one of the questions. The question 'How would you say "This witch smells very bad!" ?' keeps showing that I chose the same wrong answer, even though I am not choosing that response. This has happened like 5 times in a row and has reduced my lesson score!

The response it keeps showing as chosen -> Cette sorcière sent très mauvais. 

The one I actually chose -> Cette sorcière sent très mal

Does ‘copine/copain’ suggest a less serious relationship than partenaire  and does ‘êtres chers’ work for loved ones? Thanks

I find it difficult with the article 'de'.  I have reviewed the grammar lessons here to brush up my concepts but when reading online articles I still flounder. e.g.  In this article, why do we write la dangerosité du Covid-19, en cas d'opposition. Should it not be de Covid and de l'opposition? https://www.rfi.fr/fr/am%C3%A9riques/20210529-%C3%A9tats-unis-vaccination-des-plus-jeunes-la-difficult%C3%A9-de-convaincre-parents-et-adolescents. Thank you in advance for helping clarify.  

how will i know where to use etre and where to use avoir?

so I was doing a quiz on Kwiziq and the question was "C'est amusant." means: to which I answered "it is funny". It gave me an 'almost there' mark and I don't get why. It says the right one is 'This is funny'.
