Spanish language Q&A Forum

I've read the Q&A and related articles and am still confused. The sentence is: My sisters are often late, I always wait for them for two hours. When I apply the information in the lesson's Q&A, I ask myself: "For whom do I wait? For my sisters." Therefore sisters should be an indirect object. However, the quiz gives the direct object pronoun, las, as correct. Which is it and why? (Also, it would be helpful if you edited the questions so the correct answer to this appears consistently.) 

ps: it looks like Marcos and Lisa, below, are asking the same question in slightly different ways. Perhaps you can address all 3 questions as a group. Thanks!

Shouldn't an valid answer option include "Laura es "?

There is nothing in the hint to suggest that that is only a hint.

With the expression pasarselo bien, I have seen examples elsewhere written "la estoy pasando bien" (ie no reflexive pronoun and a feminine direct object pronoun) Please could you explain what the "la" refers to and if both expressions are interchangeable?

Gracias

Why can't you use "Vamos a ir allá el martes por la mañana" ?

“Como”can be written with and without accent, it depends on whether it has a interrogative or comparative function.
