French language Q&A Forum

The English translations of the futur anterieur listed here don't make sense to me. For example,  "you will have been able to sing on stage"  -- what does that even mean? 

 It does make more sense if the word "would'' was used in the English translation. As in: "If you had been there, you would have been able to sing on stage." But to use "will" doesn't seem correct. 

Not really a French question, but how do you type a dash to get a "your answer matched mine" in the writing exercises? Even if I write exactly the same as the model answer, if the phrase begins with a dash the computer doesn't credit me with getting it right. Is it something to do with the number of spaces before or after? Or is there a type of dash I'm not using? 

Frustrating as I challenge myself to get 3 or 4 "matches" per exercise, but this means half of my attempts have no chance....

In another lesson (sorry I don't know the name of the lesson, since I encounter them randomly), you specifically state that this sentence is not correct: 

"Elle me rappelle de Paula."  How is that different from "Elle se rappelle de ce garçon", which is given in this lesson as correct? It seems that "de" is not allowed in the first sentence but it is allowed in the second sentence. 

Combien a coute construire la tour Eiffel?

'Je ne peux pas entendre' versus 'Je n'entends pas' . Do these 2 sentences translate differently as the 1st indicates there is an external reason for not hearing (music too soft), while the 2nd indicates an inherent hearing loss  (deafness)? Does this apply to other Modal verbs? If so, examples really help with understanding. Thanks in advance.

Thank you
