Answer 1

The best answer is "le puedo pedir un favor " tell me if you get it correct :) 

Answer 2

Eva: Camarero, ¿LE PUEDO PEDIR UN FAVOR? Camarero: Sí, claro, dígame.

Step-by-step explanation:

As we can see, the correct answer is the last one: LE PUEDO PEDIR UN FAVOR because Eva is asking a question to the waiter. How can we say that? Well, we have to remember some things:

1. In Spanish, when asking, we always have to use question marks: ¿ and ? as a grammatical rule.
2. It could be helpful to us to take the context into account; at this respect, we have the answer of the waiter: “Sí, claro, dígame” which means “Of course, tell me” and by this point, we should know that he is ANSWERING to something. The other available options are not questions, they are orders about specific things: a menu, a beverage and a plate of soup, so we can discard them since the beginning.
3. To easily identify the questions we have to remember that Spanish is a very kind language and that, commonly, its speakers use courtesy formulas to ask for something instead of just ask for it without social rules, so we have to focus our attention in the meaning of those sentences to improve our understanding of the language.
