I noticed that an example given above " Elles ne l'ont fait expres" means They didnt do it on purpose. Im wondering why it isnt Elles n'en ont pas fait expres. Doesn't en replace phrases after de? 

Il faut que j'aille chercher mes parents

vs.  je dois chercher mes parents

vs.  il faut que je cherche mes parents

Pourquoi les autres deux réponses ne sont pas correctes?

It seems to me in the phrase 

Je n'aime pas non plus certains supporters qui peuvent être violents ou même racistes

It should be either "violentes ou racistes" ou "violents ou racists".  If the reference is "supporteurs" , I would think it would be masculine, making the adjectives masculine.

The very first example given of when to use "c'est" is:

"C'est une jolie robe."

This clearly refers to a specific dress.

But then we are told that the answer to "Tu aimes mon pull?"  should be "Oui, il est très beau."

Why is the rule for a specifc dress different than the rule for a specific sweater? Is it that "il/elle est" should be used when answering a question about a specific thing but that "c'est" can be used otherwise? 

Why does impressioné have another 'e' on the end. Is it because the speaker is feminine?

Please confirm are these Adverbial Affirmative Imperatives correct? 

- Donne-lui-en! [Give him some!]

- Emmenez-m’y!  [Take me there!]

- Emmenez-nous-y! [Take us there!]

- Amuse-t’y! / Amusez-t'y! [Have fun there!]

In this exercise, which asked to conjugate verbs in Plus-que-parfait, I wrote the following sentence: Marc lui avait souri et Gilles avait deviné tout de suite que Marc avait capturé son âme!  My « avait capturé » was marked down and corrected to be « avaient capturé ».  I cannot understand why a 3rd person plural conjugation is being used here instead of singular since the sentence talks about one person, Marc, who caught/captured Gilles’s soul.

- Tom et Sophia sont très différents ; l'un est calme et l'autre hyperactif.

- Sophia et Tom sont très différents ; l'un est calme et l'autre hyperactif.

Does it matter the Order in which the Male or Female is used, and hence the usage of l'un or l'une ?? How is this decided? Because l'autre is always gender neutral anyways.
