Which two words complete the fragment to form a standard statement: () required to attend school by law.

• A. Children are
• B. People are
• C. Students are
• D. Adults are

Answer: (A)

This item tests how to express a legal obligation with proper subject and verb. The standard way to state a requirement is to have the subject followed by “are” and then “required to” something. In school-attendance laws, the group the law typically targets is children, making the natural, common sentence: “Children are required to attend school by law.”

Other options would either feel less natural or imply a different scope. “People are” could work in some contexts but isn’t the conventional subject for compulsory schooling; “Students are” might be acceptable in some contexts but presumes enrollment and isn’t as universally applied as laws about children; “Adults are” would contradict the usual idea that compulsory attendance applies to minors.
