Spanish language Q&A Forum

This is getting old with asking a question specifying two different possible answers and then allowing only one in the grading of the question. Either sabes or conoces a should be accepted. The question does not differentiate between asking if the addressee knows of the restaurant because he/she has had experience going there or if he/she has just heard about it, a big difference.

Past tenses are confusing and these lessons do not have enough of an explainer.  In this Idefinite Past, I see:

Ella hizo una tarta para mi cumpleaños.She made a cake for my birthday.

But, under the Present Perfect lesson, I see:

He hecho un pastel de chocolate.I made a chocolate cake.

There is not enough information to distinguish between the two forms. I do not see the difference.  "I made a cake" and "she made a cake" are identical in format, yet different.  If both answers are correct- after all, there are often several ways to say the same thing, I think that needs to be reflected here if that is the case.

Can you explain?

Entender means understand, but in this example: Ella entiende de arte. - means: She knows about art. Why?

Thank you so much!

Also, when the subjunctive is used is it always part of the cuando clause?

Aunque with subjunctive when information is shared / background - why? I can't find this elsewhere, only that the subjunctive is used if the information is unimportant or irrelevant. Is this what this statement on 'shared' really means?

How does one conjugate the present subjunctive?  

I just started B1 and am being tested on it already without having been introduced to it...?

Thanks!

why ”queria” (imperfekto)? It’s not a habit. Shouldn’t it be ”quise” (preterito)?

It’s man speaking. He says ”mi novio”. Shouldn't he say "mi novia" (unless he is gay of course)?

Le encantó su sorpresa! ?? I would expect "Me encantó su sorpresa" ??

It appears that a space is missing in the bullet point: "in the subordinate sentence after quererque we use El Imperfecto Subjuntivo." 

It looks like a space may be needed in "quererque" to divide this into two words: "querer" and "que." Or is there a circumstance in which it would be correct to combine these?
