All subjective questions are expected to be constructive. How do we define that? Constructive subjective questions:

  -inspire answers that explain “why” and “how”.
  -tend to have long, not short, answers.
  -have a constructive, fair, and impartial tone.
  -invite sharing experiences over opinions.*
