Answer: The sentence that best describes a shuco is "Es un sanduche guatemalteco".
Step-by-step explanation: A 'shuco' is a Guatemalan sandwich that generally includes meat, cabagge, sausage and mustard. In that way, the sentence that best describes this word is "Es un sanduche guatemalteco", which can be translated as "It is a Guatemalan sandwich". In contrast, "postre guatemalteco" means "Guatemalan dessert", "sopa guatemalteca" means "Guatemalan soup" and "bebida guatemalteca" means "Guatemalan beverage".
