Answer 1

Yes, an observational study would be best for this scenario because a treatment is not being applied to the sample. In this case, Cesar is simply observing and comparing the grades of students who eat breakfast to those who do not, without manipulating any variables. This aligns with the purpose of observational studies, which analyze existing data rather than implementing an intervention.
