Spanish language Q&A Forum

In one of the quizes  engish scentence "After the blow, you didn't remember anything" one is asked to conjugate recordar in the El Pretérito Imperfecto tense.  I used "recordaba" but this was marked as incorrect.  recordabas was marked as corrrect. Why is the "You formal" conjugation not correct for the above scentence? 

Is it correct that "quedar" can also mean "to be (located)"?

E.g.  In a supermarket you might ask "¿Dónde quedan los cereales?"

Why lo de que? Maria is a noun. Why isn't it lo de?

In the test question about Pideselas.. The aswers the computer listed were:

1. Order them for them

2. Order them for her

3. Order them for him.

I feel #2 and #3 answers are wrong. Would you please check of that.  I could be wrong myself.  Thank you.

Please explain 'al' in Mis amigos sintieron una gran alegría al verme.

Gracias,

Ricky
