I figured out my confusion, please delete this question. I can’t find a button to delete it (which is silly).

Is there a general rule about when the definite article must be used? Eg, in this exercise why does ‘fortuna’ not have one while abundancia, prosperidad and economía do?

While i was doing the exercise ,the suggested answer was "Para ver las fotos o los videos", but here without articles? In this sentence, should we use las/los or not?

What is the difference between tan and tanto?

Can they be used interchangeably.

I thought the past participle of leer is leído. But the above example uses leídas. I have no knowledge of conjugating past participles. Please explain the usage. Thanks 

Hello,

Still a bit confused on passive SE, and have a couple questions:  (1) Do "no fault", "accidental" and "passive" SE all refer to the same thing?  And (2) Would the correct Spanish translation for "Yesterday I fixed his computer, and he has already broken it" be "Ayer le arreglé la computadora (el ordenador) y ya se lo/le ha roto”.   If correct, should I use “lo” (for “it”, the computer) or “le” as indirect object for “to him” (?).  Thank you for your input and clarification.

The lesson states the following: 

Cierto can also mean "verdadero/seguro" (true/truthful/sure/reliable). In this case, used with a noun, the adjective cierto is placed after the noun. For example:

I noticed a few mistakes here in this lesson. In some areas, for the "tu", "ellas/ellos", and "nosotros/nosotras" forms of "acaber" there are double "ba" syllables. For example, there's "acababas" instead of "acabas", "acababan" instead of "acaban", and "acababamos" instead of "acabamos". I've double checked elsewhere to verify the correct spellings of these forms and nowhere else did I find the double "ba" syllables.

One of the test questions was about the word order for this phrase and the following is considered incorrect: Por favor Marta, les trae unas copas de vino. Based on this lesson, I thought that the indirect object pronoun (les) could be placed before or after the imperative (i.e. traéles or les trae). Can you please explain the difference?

Can tanto be used instead of cuánto in some of these instances?  For example: Hemos comido tanto pollo!
