Q1. Which tea is the traditional base for classic milk tea in Taiwanese bubble tea shops?
- A. Green tea
- B. Black tea ✓
- C. White tea
- D. Oolong tea
Why: Black tea, often Assam or a blended black tea, is the traditional base for classic milk tea because its robust, malty flavor stands up well to milk and sweetener.

- B. 90°C (194°F)
- C. 75-80°C (167-176°F) ✓
- D. 50°C (122°F)
Why: Green tea is delicate and brewing it at 75-80°C prevents scalding the leaves, which would release excess tannins and cause a bitter, grassy taste.

- A. The amount of tea leaves used
- B. The duration the leaves sit in hot water ✓
- C. The temperature of the water
