The question, "Say 'the same' thing twice over," highlights the phrase "the same," which is indicative of a demonstrative quality. Demonstrative words are those that point to specific entities or ideas, often signifying identity or similarity. In this context, "the same" serves to indicate that two items or concepts are identical or equivalent in some manner.

The options presented (demonstrative, descriptive, distributive, and indefinite numeral) can be analyzed as follows:

- **Demonstrative**: This correctly aligns with "the same," as it effectively directs attention to a specific set of items that share a quality.
- **Descriptive**: While it describes a quality, it does not inherently signify sameness or identity.
- **Distributive**: This refers to a distribution among several entities, which does not fit the phrase "the same."
- **Indefinite Numeral**: This denotes a quantity without giving a specific numeral, which is unrelated to the provided phrase.

Consequently, "the same" encapsulates the essence of demonstrating similarity or identity, making "A) Demonstrative" the appropriate answer.
