Causal Reasoning – Plant properties: “Jade plant has thick leaves and it requires little water.” Decide which conclusions follow logically: (I) All plants with thick leaves require little water; (II) Jade plants can be grown where water is not abundant.

Answer
Correct Answer: Only conclusion II follows
Explanation
Given data
- Observation about one species: Jade has thick leaves and low water requirement.
- Conclusion I: Universal generalization for all thick-leaf plants.
- Conclusion II: Practical cultivation feasibility in low-water regions.
Concept/ApproachFrom a single example, universal generalizations are invalid. However, the cited property (low water need) supports a practical conclusion for that species.
Step-by-step evaluation• I overgeneralizes from one plant to all plants—this is a classic fallacy of hasty generalization. It does not follow.• II uses the specific trait (requires little water) to infer suitability in water-scarce areas. This is a reasonable, direct implication → II follows.
Common pitfalls
- Confusing an existence claim (“Jade has…”) with a universal rule (“All plants have…”).
Final AnswerOnly conclusion II follows.
