Answer 1

Correct choices:
- There are four classes of jellyfish, and they are known as Scyphozoa, Cubozoa, Hydrozoa, and Staurozoa.
- Jellyfish is eaten as a delicacy in some parts of the world, even though it tastes rather flavorless.

Why: The classification statement matches accepted taxonomy of medusozoan cnidarians. The eating statement is a well-documented cultural/culinary fact (e.g., in parts of East and Southeast Asia).
