Answer:
You have to write it out completely as a sentence.
You have to write "Catalina looks at ____"
1. Catalina nos mira.
2. Catalina te mira.
3. Catalina los mira.
4. Catalina os mira.
5. Catalina me mira.
It's changing the indirect object pronoun.
Hope it helps :) I had trouble with this one too and couldn't find any helpful answers.
