Hola, susana. pablo. ¿qué tal? answer for blank 1:

"in english, write six to eight sentences comparing cultural aspects of greetings in spanish-speaking countries with greetings in your own culture. use what you learned in the lessons to tell about three differences and three similarities. discuss non-verbal greetings and how respect is shown. you may also include verbal greetings, but do not simply translate phrases from one language to another."
