Verbal Reasoning
"DOST-SEI Verbal Reasoning! Logic through language - analogies, relationships, at critical analysis. Sharpen your verbal intelligence, iskolar! This section tests your ability to understand word relationships, draw logical conclusions, and analyze arguments using language-based reasoning."
1. Verbal Analogies 🔄
Analogies test your ability to recognize relationships between words. The format is: A is to B as C is to ____. You must identify the relationship and apply it to find the answer.
| Relationship Type | Description | Example |
|---|---|---|
| Synonym | Words with similar meanings | Happy : Joyful :: Sad : Melancholy |
| Antonym | Words with opposite meanings | Hot : Cold :: Light : Dark |
| Part : Whole | Component is part of a larger thing | Petal : Flower :: Finger : Hand |
| Whole : Part | Larger thing contains the component | Tree : Branch :: House : Room |
| Cause : Effect | One thing leads to another | Fire : Smoke :: Rain : Flood |
| Tool : Function | Object used for specific purpose | Hammer : Nail :: Saw : Wood |
| Worker : Tool | Professional uses specific equipment | Carpenter : Hammer :: Chef : Knife |
| Degree/Intensity | Same quality at different levels | Warm : Hot :: Cool : Cold |
| Category : Example | General class and specific member | Fruit : Apple :: Vegetable : Carrot |
| Object : Characteristic | Thing and its quality | Sugar : Sweet :: Lemon : Sour |
💡 Analogy Solving Strategy:
- Create a sentence describing A's relationship to B
- Apply the same sentence to C and the answer choices
- The answer that fits the sentence pattern is correct
Example: "A PETAL is part of a FLOWER" → "A FINGER is part of a HAND"
2. Sentence Completion 📝
These questions test vocabulary and logical reasoning. You must choose the word or phrase that best completes the sentence.
Signal Words to Watch:
- However, but, although, despite: Expect contrast
- Therefore, thus, consequently: Expect result
- Moreover, furthermore, also: Expect addition
- Because, since, due to: Expect cause
Solving Steps:
- Read the entire sentence
- Identify signal words
- Predict what type of word fits
- Eliminate wrong choices
- Check grammatical fit
Common Patterns:
| Contrast: | "Although he was tired, he remained _____" → Answer: energetic/alert (opposite of tired) |
| Cause-Effect: | "Because of the drought, crops _____" → Answer: withered/died (effect of drought) |
| Definition: | "A _____, or fear of heights, can be debilitating" → Answer: acrophobia |
3. Logical Arguments & Critical Reasoning 🧠
These questions test your ability to analyze arguments, identify assumptions, and draw valid conclusions.
| Question Type | What It Asks | Strategy |
|---|---|---|
| Main Conclusion | "What conclusion can be drawn?" | Find what the premises support |
| Assumption | "Which assumption is made?" | Find unstated but necessary premise |
| Strengthen | "Which strengthens the argument?" | Find evidence supporting conclusion |
| Weaken | "Which weakens the argument?" | Find counterevidence or flaw |
| Inference | "What can be inferred?" | Find what must be true based on given info |
Argument Structure:
- Premise: The evidence or facts given
- Conclusion: The point being argued (often after "therefore," "thus," "so")
- Assumption: Unstated belief connecting premise to conclusion
4. Common Logical Fallacies ⚠️
Recognizing flawed reasoning helps you evaluate arguments and avoid incorrect answers.
| Fallacy | Description | Example |
|---|---|---|
| Ad Hominem | Attacking the person, not the argument | "You can't trust his research; he's too young." |
| Hasty Generalization | Drawing broad conclusion from few examples | "I met two rude locals, so everyone there is rude." |
| False Cause | Assuming correlation equals causation | "Sales increased after the ad ran, so the ad caused it." |
| Appeal to Authority | Citing unqualified authority as proof | "This actor says the medicine works, so it must." |
| Circular Reasoning | Using conclusion as premise | "He's trustworthy because he always tells the truth." |
| False Dilemma | Presenting only two options when more exist | "You're either with us or against us." |
5. Syllogisms & Deductive Reasoning 📐
Syllogisms are logical arguments with two premises and a conclusion. Understanding valid syllogistic forms is crucial for verbal reasoning.
Valid Syllogism:
Premise 1: All mammals are warm-blooded.
Premise 2: Dogs are mammals.
Conclusion: Therefore, dogs are warm-blooded. ✓
Invalid Syllogism:
Premise 1: All cats have fur.
Premise 2: My dog has fur.
Conclusion: Therefore, my dog is a cat. ✗
Key Terms:
- All A are B: Universal affirmative - every single A is B
- No A are B: Universal negative - not a single A is B
- Some A are B: Particular affirmative - at least one A is B
- Some A are not B: Particular negative - at least one A is not B
💡 Tip: Use Venn Diagrams!
Drawing circles to represent categories helps visualize relationships and test whether conclusions are valid.
6. Word Classification & Odd One Out 🎯
These questions ask you to identify which word doesn't belong to a group based on meaning, category, or relationship.
Classification Bases:
- Category: Apple, Banana, Carrot, Orange (Carrot = vegetable)
- Part of speech: Run, Jump, Beautiful, Swim (Beautiful = adjective)
- Meaning relationship: Happy, Joyful, Sad, Elated (Sad = antonym)
- Degree: Warm, Hot, Boiling, Cold (Cold = opposite direction)
- Association: Doctor, Hospital, School, Nurse (School = different setting)
- Function: Car, Bus, Train, Helicopter (Helicopter = air travel)
