Strictly factual question

A strict question of fact occurs has an answer determined solely by the state of the material universe, and sufficiently straightforward math, in a clearly understandable way - none of our uncertainty about this question is about definitions, values, or viewpoints; we are just wondering which quarks go where.

Questions of strict fact:

• What happens if I press the giant red button?(*)
• Did Sally claim more charitable donations as an income tax deduction than Bob?
• Are there unicorns anywhere on Earth?
• Will Peano arithmetic prove a contradiction if I search all the proofs less than a billion steps long?

Questions not yet of strict fact:

• Should I press the giant red button?
• Is Sally a more charitable person than Bob?
• Do unicorns exist?
• Will Peano arithmetic prove a contradiction if I search for one forever?

Why the second group aren't yet questions of strict fact:

• Because the notion of should has not yet been fully specified or determined.
• Because we haven't said exactly what it means to be charitable.
• Because "exist" is a bit of a deep notion we don't fully understand, plus, for example, there could be unicorns ${10}^{1,000,000}$ lightyears away, etcetera.
• Because the notion of 'forever' is more mathematically fraught than 'for ten to the billionth power years', and there are multiple models of infinity.

(*) At least, this is a straightforward question so long as we don't poke too hard at the nature of what-if counterfactuals.
