Answer:
¿Olivia es de Argentina?
¿El profesor es de Alemania?
¿Carlos y yo somos de Canadá?
Step-by-step explanation:
These affirmative sentences are complete and correct. I see you're trying to convert them into questions. The simplest kind of question in Spanish (similar to English) is yes/no questions, and the structure is:
¿ + Subject + verb + complement + ?
In this case, because the sentences are already in the correct order, you just have to add the question marks, remember, in Spanish they go both at the beginning of the sentence and in the end.
