Answer 1

A string variable named studentName and a Boolean variable named isAbsent

Reason: studentName is a clear, descriptive string for the name; isAbsent is a Boolean (true/false) that directly represents whether the student is currently absent. Numeric variables aren't appropriate for a yes/no state, and single-letter names are unclear.
