📚 Study Notes – Reasoning Ability
Topic: Analogy
(For Mizoram Police Sub‑Inspector (SI) Examination)
1️⃣ Simple Explanation
An analogy is a mental exercise that tests the ability to find a relationship between two pairs of words, phrases, or objects.
- Structure: A : B :: C : D → “A is to B as C is to D.”
- The task is to identify the relationship (synonym, antonym, part‑whole, function, etc.) and then select the word that preserves that relationship in the second pair.
Analogy questions assess:
- Vocabulary breadth
- Logical reasoning
- Pattern recognition
2️⃣ Key Points to Remember
| # | Key Point | Why It Matters |
|---|---|---|
| 1 | Identify the relationship first | The relationship (synonym, antonym, cause‑effect, etc.) is the “key” to solving the problem. |
| 2 | Common relationship types | - Synonym / Antonym - Part‑Whole - Function / Use - Cause‑Effect - Object‑Tool - Activity‑Result - Material‑Made‑Of - Size/Quantity |
| 3 | Look for word pairs that are “in the same class” | Example: Doctor : Patient :: Teacher : Student – both are professional‑client relationship. |
| 4 | Eliminate distractors | Distractors often share only one aspect of the relationship or are completely unrelated. |
| 5 | Beware of “double relationships” | Some analogies involve two layers (e.g., Bird : Feathers :: Fish : Scales – both “animal‑body part” and “skin‑type”). |
| 6 | Use process of elimination | If unsure, rule out obviously wrong options first. |
| 7 | Practice with real‑life contexts | Analogies often mirror everyday relationships (tools, roles, causes, etc.). |
3️⃣ Worked Example
Question
A : B :: C : ?
A = Lighthouse
B = Beacon
C = Hospital
Solution
| Step | Action | Reasoning |
|---|---|---|
| 1 | Identify relationship A : B | A lighthouse provides a beacon (light) to guide ships. |
| 2 | Determine the relationship type | Lighthouse → Beacon = source : signal/indicator (object that emits a signal). |
| 3 | Find a word for C that fits the same type | Hospital → ? → The hospital emits a signal that indicates health status? Not quite. Think of what a hospital provides that signals to people. |
| 4 | Re‑evaluate relationship | A lighthouse is to a beacon as a hospital is to a ward? No. A better fit: Hospital provides treatment → treatment is the “signal” of care. |
| 5 | Choose the option that matches “source : signal” | The best choice is Medicine (the hospital provides medicine, which signals cure). |
| 6 | Final answer | Medicine |
Answer: Medicine
(If the options were Doctor, Patient, Ward, Medicine, the correct answer would be Medicine.)
4️⃣ Quick Revision Summary
| Concept | Quick Check |
|---|---|
| Analogy structure | A : B :: C : D |
| Common types | Synonym, Antonym, Part‑Whole, Function, Cause‑Effect, Object‑Tool, Activity‑Result, Material‑Made‑Of |
| Solve by | 1️⃣ Identify relationship of first pair 2️⃣ Apply same relationship to second pair 3️⃣ Eliminate wrong options |
| Tips | • Look for same‑class pairs (roles, objects, functions). • Use process of elimination. • Beware of double relationships. |
| Practice | Solve at least 10 analogy questions daily; review explanations for wrong answers. |
📌 Final Tips for the Exam
- Read the question carefully – the analogy pairs may be subtle.
- Time Management – allocate ~30 seconds per analogy; if stuck, skip and return.
- Vocabulary Strength – build a list of commonly used analogy pairs (e.g., teacher‑student, doctor‑patient, engine‑fuel).
- Mock Tests – take timed practice tests to simulate exam conditions.
Good luck, and keep practicing! 🚀
