Question

Which action would best support an in-depth formal inquiry?

asking students how they feel about the development of a new football field
learning more about the students competing for student government positions
investigating how students’ well-being is affected by eating a balanced breakfast

Answer 1

Investigating how students’ well-being is affected by eating a balanced breakfast.

Reason: it’s testable and measurable (you can define variables, collect quantitative and qualitative data, use controls or comparison groups, and analyze results), whereas the other options are primarily opinion-gathering or background information.
