Why is 'Daphné apprend-elle le français' correct while 'Daphné apprend-t-elle le français' is marked wrong. All the examples in the lesson add 't' when the verb does'nt elide.

Quand La Premiere Guerre Mondial a-t-elle commence.  This seems an awkward construction, but perhaps not.  Could one say: La premiere Guerre Mondial quand a-t-elle commence?  Please excuse the lack of punctuation. 

Interesting, the answer is probably, "Is Lucie coming to the cinema" but, "Lucie.. is she coming to the cinema" might change the emphasis but would be perfectly correct in English...

Can we please have some examples of statements turning into questions in these cases? I am finding it hard to follow how the order of words changes in each situation. Many thanks!

Why isn't the question above inverted? Is it specific to the usage of "que"?

George's question is interesting! Very often, in English, you may hear the following. "The front door, was it locked?".  Also similarly, "Cécile, isn't she exceptional?". The screeching-brakes urgency of the first and the wonderment accolade of the second is relayed in the format. And yet the corresponding translation is rejected in the answers. How can you repeat the effect in French if not as follows.  La porte d'entrée, etait-elle verouillée?/Cécile, n'est-elle pas exceptionnelle?

Please can someone explain why, when there is an inverted question and the subject is a noun, there is not a comma after the subject, as I was taught when I learned French at school?

Is this type of sentence structure formal? I am having difficulty in knowing which is formal and which is informal. When will a sentence like this be used? 

I would greatly appreciate if there was some sort of guide for this. Thanks!

Is it absolutely wrong to use est-ce que to form a question using names? Thanks.
