Difficulty: Easy
Correct Answer: None of these
Explanation:
Introduction / Context:
The pair “Comets : Meteors” parallels two distinct but related astronomical phenomena, not a class–member relation in a strict taxonomic sense. We must identify an option that mirrors an appropriate relation (closely related phenomena), or else conclude none fits adequately.
Given Data / Assumptions:
Concept / Approach:
Test each option for parallel structure (two peer phenomena of the same domain) rather than cause/effect, container/content, or attribute/behavior mismatches.
Step-by-Step Evaluation:
Verification / Alternative check:
Since none captures “two peer natural phenomena” within the same scientific domain (like “earthquakes : volcanoes”), the best choice is “None of these.”
Why Other Options Are Wrong:
Common Pitfalls:
Accepting any two related nouns without checking relational parity (phenomenon ↔ phenomenon).
Final Answer:
None of these
