Final answer:
The student's question is about the regular and happy hour pricing of red and white wine. Prices vary, but discounts during happy hour typically range from 10-15%. A rare or vintage wine could be significantly more expensive, potentially nearing $1,000 for a glass.
Step-by-step explanation:
The question appears to be concerning the pricing of red and white wine during normal hours and during a happy hour at a restaurant or bar. Although the specifics of wine prices can vary greatly from one establishment to another, there are some general trends we can discuss. During a happy hour, many establishments offer discounts on drinks, which can range between 10-15%.
If a regular drinking glass of wine costs nearly $1,000 outside of happy hour, it would be quite an expensive wine, perhaps a rare or vintage bottle, which is more than 1,000x more expensive than the average glass. The volume and mass mentioned, 'A few dozen times more volume, and about 10² in mass,' do not typically apply to a single glass of wine and could be referring to a different context, such as the difference between a standard serving and a larger, possibly commemorative bottle.
