In a quiz question (20% is a small number),       why is the answer el "20 %" not accepted? The lesson seems to suggest that either that or El '20 por ciento" should be ok. Thanks.

For ‘to need to’, when to use necessitated and when to use tener que?

Alicia, ¿a qué hora te ducha por la mañana?

In one quiz answer it marked me wrong for choosing “Se llama [girl’s name],” saying I should have chosen “Ella se llama…” Then in the next quiz I chose “Él se llama” and it was marked wrong, saying I should have chosen “Se llama.” I’m confused, what is the difference?

Hi, did I miss the part where the botes explain the difference between when to use the a ending for me olvida instead of me olvido? 

The english text referred to great legends, so I chose gran, but it was marked incorrect. That seems to conflict with the answers given in the community.

Fernando ___ a Luisa... In another lesson you said that when naming the person, the "le, les" cannot be omitted. I used "estuvo explicándole" but the right answer is "estuvo explicando." Why? Thanks!

Greetings,  I have a question about the sentence “Mientras, los otros niños hacíamos una fila…” If the subject is los otros niños, should the verbs in this sentence be conjugated in the third person plural? Hacían? Entraban? There is no indication that the narrator is including himself in the group of kids waiting in line. Please help me understand. Thank you. 

¡Anda, qué bien te han dejado en la peluquería!

Could this also be stated as? ...

¡Anda, qué bien te han hecho en la peluquería!

Or is that rude? I probably wouldn't have thought to use dejado.
