The following text discusses culinary history.
Sushi, now a global phenomenon, was originally a method of food preservation rather than a delicacy. Ancient cooks in Southeast Asia packed fish in fermented rice to keep it edible for months. The rice was discarded, and only the preserved fish was eaten. It wasn't until the early 19th century in Edo (now Tokyo) that chefs began serving fresh fish on seasoned rice as a quick street food—the style we recognize today as sushi.
According to the text, how did sushi's purpose change over time?
From street food to preserved delicacy
From preservation method to fresh food enjoyed for taste
From vegetarian dish to fish-based meal
From expensive restaurant cuisine to common fare
Correct Answer: B
Choice B is the correct answer. The text describes sushi evolving "from a method of food preservation" to a fresh food experience "we recognize today."
- Evidence: Originally for preservation; now served fresh.
- Reasoning: The fundamental purpose shifted from practical to culinary.
- Conclusion: Preservation to fresh enjoyment is the key change.
Choice A is incorrect because this reverses the actual progression. Choice C is incorrect because fish was always involved, not vegetarian to fish. Choice D is incorrect because it started as street food, not expensive cuisine.
