French language Q&A Forum

For the very first sentence, I used "formidable" instead of "excellent" and this was not accepted as correct. Is this word out of fashion? Or just used in certain contexts? Thanks for your help!

Pourquoi elle trouve Andrew charmant ? Pourquoi pas elle trouve qu'Andrew est charmant ?

The lesson states that « que » always follows « Je trouve »  yet « Je trouve que Halloween est... » is given as a right answer. 

The first 2 answers in the multiple choice list are the same so I chose both and got one wrong.  What happened?

Pour la question 12, puis-je écrire, 'je lutterais contre le machiavélique Cardinal Richelieu'?

1. Can we aussi say ' Il ne devrait y avoir aucun problème ' ?

2. I wanted to check with you what type of pillows you use. 

The answer is je voulais vérifier avec vous quel type d'oreillers vous utilisez. 

Why there is no 'que' after 'oreillers' ? 

I am finding these extremely difficult, for some reason, despite doing a lot of wotk on ce que / que etc. It would be helpful if you could find some way of explaining why the wrong answers are wrong.
