I'm noticing that most verb tenses in this passage are in the present tense. I'm wondering if there's a general rule about when to use the present versus the future tense in this kind of historical account. I see one sentence that says "Plus tard, elle aura son diplome en sciences physiques..." Given that the sentence starts with "plus tard," it makes sense to me that the following verb is in the future tense, but later in the passage I'm seeing "Plus tard, en 1911, Marie recoit le Prix Nobel..." In this case "plus tard" is followed by the present tense. I'm wondering if the choice of tense is stylistic or if there is a subtle difference in meaning or how does one decide which tense is appropriate? Thanks in advance for your help!

Which would be the correct preposition to use for this sentence:
"Aurélie is on the train to London."

Aurélie est dans le train à London.

Aurélie est dans le train pour London.

In the lesson ‘Que = Whom, which, that (relative pronouns)’ an example sentence is given as:

‘La femme que je dessine’

An example sentence from this lesson is: ‘Le chat, auquel tu as fait peur’ OR ‘Le chat, à qui tu as fait peur’ 

I’m struggling to understand why is ‘Le chat, que tu as fait peur’ is not used?

Thanks

I'm curious to know why it's not "J'ai besoin DU temps pour réfléchir" in this sentence?  What happens to the definite article "le" for temps?

This is in the lesson examples:

Sophie a mal à l'oreille.Sophie's ear aches. 
Sophie has an earache

But when I entered « Aurélie a mal à l’oreille » as the quiz answer it said I was wrong and should have answered « Aurélie a mal aux oreilles ». Which version is actually correct?
