Do all classes of DG have divisions?

• A. Yes
• B. No
• C. Sometimes
• D. Not sure

Answer: (B)

This question tests whether a universal property holds across all categories: do every class of DG have divisions? The best answer is that not all DG classes are subdivided. In practice, divisions are introduced only when there is meaningful internal variation to separate; some classes are simple and treated as a single unit, while others are broken into subdivisions. Because there exist DG classes without any divisions, the statement that all of them have divisions isn’t true. If you considered the other options, they either overstate a universal rule (Yes) or don’t fit the idea of a universal assessment (Sometimes implies a mixed rule without addressing the universal claim), and Not sure isn’t a meaningful answer in this context.
