📚 Analogy – Study Notes for Assam TET (Reasoning Ability)
Analogy is a relational reasoning skill that tests how well you can see the relationship between two items and then apply that same relationship to a new pair.
In TET, it is usually presented as a 4‑option multiple choice of the formA : B :: C : ?
The goal is to pick the option that best completes the analogy.
1. Conceptual Foundation
| Concept | Explanation | Typical Example |
|---|---|---|
| Analogy | A comparison that shows similarity in relationship rather than in appearance. | Doctor : Medicine :: Teacher : Book (both “use” the second item). |
| Relational Pairs | Two items are related by a single relationship (cause‑effect, part‑whole, function, etc.). | *Water : Liquid :: Ice : solid |
| Analogy Types | 1. Semantic – meaning based (synonyms, antonyms). 2. Structural – grammatical or morphological. 3. Spatial/Temporal – location/time. 4. Causal – cause‑effect. 5. Functional – tool‑purpose. |
*City : Highway :: Town : Road (functional). |
Key Insight: The relationship is what matters, not the items themselves.
2. Systematic Approach to Solving
| Step | What to Do | Why It Matters |
|---|---|---|
| 1. Identify the relation in A : B | Examine all possible relations: part‑whole, cause‑effect, function, similarity, sequence, etc. | Helps narrow down options. |
| 2. Test each relation on the pair C : ? | Choose the candidate that satisfies the same relation. | Confirms which relation is correct. |
| 3. Eliminate options that break the relation | If an option violates the relation, discard it. | Quick elimination of many distractors. |
| **4. Check for ambiguity | If more than one option satisfies the relation, re‑evaluate the relation or look for a strict relation. | Avoids multiple correct answers. |
| 5. Final verification | Double‑check that the chosen answer fits exactly the same relational pattern. | Ensures accuracy. |
Tip: Write down the relation after each pair if it helps.
3. Common Relational Patterns (with Examples)
| Pattern | Symbolic Way | Example | How to Detect |
|---|---|---|---|
| Part‑Whole | Part : Whole | Leaf : Tree | Look for “is a component of”. |
| Whole‑Part | Whole : Part | Car : Wheel | Reverse of above. |
| Cause‑Effect | Cause : Effect | Heat : Melt | Identify “makes” or “produces”. |
| Effect‑Cause | Effect : Cause | Cold : Freeze | Reverse. |
| Function‑Tool | Function : Tool | Cook : Pan | Who or what uses the other. |
| Tool‑Function | Tool : Function | Pen : Write | Reverse. |
| Similarity | Object1 : Object2 (similar) | Ant : Bee | “Both” or “Similar in …” |
| Opposite / Antonym | Word1 : Word2 (opposite) | High : Low | Look for contrasting prefixes/suffixes. |
| Sequence / Order | Earlier : Later | Spring : Summer | Temporal or sequential. |
| Hierarchy / Category | Specific : General | Piano : Musical Instrument | “Is a type of”. |
| Degree / Proximity | Closer : Farther | Cousin : Uncle | “Closer in relation”. |
Remember: Often, only one pattern fits all four items. If more than one pattern fits, the test may be poorly designed or you mis‑identified the relation.
4. Trick Points & Pitfalls
| Pitfall | What to Watch For | Fix |
|---|---|---|
| Multiple Relations | “Doctor : Medicine” can be function or tool, but Doctor : Knowledge would also fit “uses”. | Look for the most natural relation. |
| Homonyms | Well can mean “source of water” or “healthy”. | Context matters; choose the sense that keeps the relation consistent. |
| Distractor Options | Option that is a close match but violates a subtle part of the relation. | Re‑evaluate the relation with the option. |
| Semantic vs. Structural | “Cat : Kitten” (age) vs. “Cat : Paw” (part). | Identify if the relation is temporal or physical. |
| Over‑Simplification | Assuming “A : B” is part‑whole when it’s actually function. | Test other relations before finalizing. |
| Wordplay | “Rise : Fall” vs. “Fall : Rise” |
