Compartido is your answer
Hello. Unfortunately it is not possible to have access to the unit that the question refers to, which makes it impossible for it to be answered. However, I will try to help you in the best possible way.
Cognates are words from different languages that have the same origin and therefore can present the same spelling or similar spelling. It is common for cognates to have the same meaning as well, but there are false cognates, which are extremely similar words that have different meanings.
An example of cognates between English and Spanish are the words "family" and "familia."
Hmmm.. That looks right to me. Sometimes, teachers will use calmada instead of tranquila. You can ask if that is the case here. Otherwise its possible that the teacher made a mistake. If you are still confused, I would just as whoever your teacher is. I'm sure its a mistake on their part :)
Good luck!!
