7. Existence / D. Theories of Reality / 11. Ontological Commitment / e. Ontological commitment problems
All scientific tests will verify mathematics, so it is a background, not something being tested [Sober]
8. Modes of Existence / B. Properties / 9. Qualities
Whiteness isn't created in an alteration, because it is just this-being-white [Oresme]
10. Modality / B. Possibility / 8. Conditionals / a. Conditionals
