Explanation:

Question 3

To determine the passage's topic, we analyze each option:

• Option A focuses on life without sunlight generally, not specific to hydrothermal vents.
• Option B emphasizes why hydrothermal vents are surprising for life, but the main idea is more about life's evolution and survival there, not just the surprise.
• Option C aligns with the typical focus of passages on hydrothermal vent life, which often cover how life adapts, evolves, and survives in that extreme environment.
• Option D is about why most life can't survive there, which is not the main focus of such passages (they usually highlight the life that does survive).

Question 4

We analyze the definitions:

• "Hierarchy" is defined as a system that organizes or ranks things by importance (e.g., a corporate hierarchy ranks employees by role importance).
• "Occupation" refers to a job or profession.
• "Species" is a group of living organisms.
• "Challenges" are difficulties or problems.

Only "hierarchy" matches the given definition.

Answer:

C) how life has evolved and survived around hydrothermal vents
