What criteria should be set to filter records in a query for students classified as either Junior or Senior?

To filter records in a query for students classified as either Junior or Senior, the criteria that should be set involves specifying the classification directly. By selecting "Classification equals Jr or Sr," the filter ensures that only those students who meet these specific classifications are included in the result set. This precise criterion effectively narrows down the data to exactly what is needed for the inquiry.

Using terms like "equals" allows for clear identification of records, and the logical use of "or" accommodates both classifications in one criterion. By contrast, the other options introduce qualifiers that do not specifically focus on the desired class standings of Junior and Senior students. For instance, considering criteria related to credits without direct reference to classification would not yield the correct subset of students; they may include individuals who are neither Juniors nor Seniors. Therefore, specifying the classification as the filtering criterion is the most direct and effective approach to achieving the intended result.
