Según yo la forma correcta de decirlo es:
A Mateo y Marta les duelen los ojos.
Cayo Santa Maria has no people living in it
I’m confused on what your asking
1. visito
2. entró
3. hacemos
4. salí
You could say that you are less intelligent, as intelligent or more intelligent that Jaime. The thing is, you only have the options to write one thing because not all options would be correct:
Jaime es inteligente pero you soy más inteligente que él. - Jaime is intelligent but I'm more intelligent than him.
Hope it helped,
