Question

Select the dining etiquette you’re expected to follow at an upscale restaurant. Sentarse en la mesa. No hay necesidad de hacer una reserva. Poner los codos sobre la mesa. Poner la servilleta sobre las piernas.

Answer 1

The translation is: sit at a table. There is no need to make a reservation. Put your elbows on the table. Put a napkin on top of your legs.

So the answer would be: Sentare en la mesa. Poner la servilleta sobre las piernas.

This is what you would normally do at a restaurant, hope this helps!

Answer 2

Answer:

If you are in an upscale restaurant, you must follow certain rules, such as make a reservation before, when you finally go to your designed table, you should sit and put the napkin on your legs, eat slowly and be polite.  

Therefore, the correct dining etiquette among the options are:

Sentarse en la mesa (sit on the table)

Poner la servilleta sobre las piernas (put the napkin on the legs)

The options No hay necesidad de hacer una reserva (There is no need to make a reservation) and Poner los codos sobre la mesa (Put your elbows on the table) are not according the dining ettiquete rules.
