I know that ils is used for masculine or mixed masculine and feminine groups and elles is used for feminine groups. But what if there are more feminine than masculine objects such as a group of one man and ten women? Would it then be acceptable to use 'elles' to refer to that group or would I still have to use ils even if only thing is masculine?

Can you have "je courrai sur le tapis roulant pour une demie heure" because its the future tense?

I would have thought the pastry would have been called "le gâteau" not "le biscuit" --the former is a cake, the latter is a cookie, and a bûche is a kind of cake.  Also, do some recipes for la bûche call for spreading ganache inside?  I have only read recipes that call for a whipped cream sort of filling, saving the ganache for the exterior.  I'm about the make my annual bûche de Noël and wish it were as simple as this version!

Why is the phrase "notre prof de science nous demandait de préparer ..." in imparfait not passé composé? Since the requests occurred at specific points in time I thought it would be passé composé. Is it because the requests were repeated each year?

In one of quiz’s question it asks something like qu’est cet homme? And the answer is ; c’est (name of the person). I was wondering if we can say “il est…” instead of c’est. Since its asking about a particular person and while studying “il/elle est” it says if its asking about a specific thing we should use it. I need a bit clarifications please.
