Answer
Correct Answer: Aphid : Paper
Explanation
Introduction / Context:Three pairs correctly link a pest to what it commonly damages. One pair is incorrect: aphids attack plants by sucking sap, not paper.
Given Data / Assumptions:
- Moth : Wool → clothing moths damage wool.
- Termite : Wood → termites damage timber/wooden structures.
- Locust : Plant → locust swarms devastate crops.
- Aphid : Paper → incorrect target; aphids infest plants.
Concept / Approach:Validate each pest→target based on common biology/agriculture facts.
Step-by-Step Solution:
1) Confirm B–D as correct.2) Flag A as incorrect.3) Therefore A is the odd pair.Verification / Alternative check:Garden references list aphids as plant pests (leaves/stems), never a paper pest.
Why Other Options Are Wrong:They show well-known pest damages.
Common Pitfalls:Confusing paper pests (e.g., silverfish) with aphids.
Final Answer:Aphid : Paper
