How to Solve: CUET Reasoning – Statement and Assumption, Conclusion, Argument

Introduction

"Imagine you’re reading a news headline: ‘Government bans plastic bags to reduce pollution.’ Can you spot the hidden assumption? Or decide if the argument is strong enough? Master this, and you’ll ace CUET Reasoning—and real-world debates!

What You Need To Know First

1. Basic logic terms: Know what a statement, premise, and conclusion are.
2. Implicit vs. explicit: Understand that assumptions are unstated but necessary for the argument to hold.
3. Strong vs. weak arguments: Recognize when an argument is logically sound or flawed.

Key Vocabulary

Formulas To Know

(No mathematical formulas—these are logical "rules" to apply.)

1. Assumption Identification Rule
2. If the statement is true, what must also be true for it to hold?

3. Memorise This.: Assumptions are necessary but unstated conditions.

4. Conclusion Validity Check

5. Does the conclusion necessarily follow from the premises?

6. Memorise This.: If yes → Valid. If no → Invalid.

7. Argument Strength Test

8. Do the premises provide strong support for the conclusion?
9. Memorise This.:
   • Strong: Premises guarantee the conclusion.
   • Weak: Premises suggest but don’t prove the conclusion.

Step-by-Step Method

For Assumptions:

1. Read the statement carefully. Underline key claims.
2. Ask: "What must be true for this statement to make sense?"
3. Eliminate options that:
4. Are already stated (not assumptions).
5. Are irrelevant (don’t affect the statement).
6. Are too extreme (e.g., "all," "never" unless necessary).
7. Pick the option that must be true for the statement to hold.

For Conclusions:

1. Read all given statements. Identify premises and conclusion.
2. Check if the conclusion logically follows.
3. If yes → Valid.
4. If no → Invalid (even if the conclusion is true in real life).
5. Watch for:
6. Overgeneralization (e.g., "Some X are Y → All X are Y").
7. Irrelevant premises (e.g., "Dogs bark. Cats meow. So, the sky is blue.").

For Arguments:

1. Identify the conclusion (look for words like "so," "therefore," "thus").
2. List the premises (supporting statements).
3. Test strength:
4. Strong argument: Premises prove the conclusion.
5. Weak argument: Premises suggest but don’t prove the conclusion.
6. Eliminate options that:
7. Are irrelevant to the conclusion.
8. Contradict the premises.
9. Are too broad (e.g., "always," "never" without proof).

Worked Examples

Example 1 - Basic (Assumption)

Statement: "The government should increase taxes on cigarettes to reduce smoking." Options: A) Smoking is harmful to health. B) Higher taxes will make cigarettes unaffordable. C) People will stop smoking if cigarettes are expensive. D) The government wants to reduce smoking.

Solution: 1. Key claim: "Increase taxes to reduce smoking." 2. Ask: "What must be true for this to work?"
- The assumption is that higher taxes will reduce smoking. 3. Eliminate:
- A) Already stated (smoking is harmful).
- B) Too specific ("unaffordable" isn’t necessary—just more expensive).
- D) Irrelevant (government’s intent isn’t the assumption). 4. Correct answer: C) People will stop smoking if cigarettes are expensive.

What we did and why: We looked for the unstated link between taxes and smoking reduction. Option C is the necessary assumption.

Example 2 - Medium (Conclusion)

Statements: 1. All doctors are educated. 2. Some educated people are rich. Conclusion: Some doctors are rich.

Solution: 1. Premises:
- All doctors → educated.
- Some educated → rich. 2. Check logic:
- Does "some educated are rich" necessarily mean "some doctors are rich"?
- No. The rich educated people might be non-doctors. 3. Conclusion is invalid.

What we did and why: We tested if the conclusion must follow. It doesn’t—so it’s invalid.

Example 3 - Exam Style (Argument Strength)

Argument: "Most students who study daily get good grades. Priya studies daily. Therefore, Priya will get good grades." Question: Is this a strong or weak argument?

Solution: 1. Identify conclusion: "Priya will get good grades." 2. Premise: "Most students who study daily get good grades." 3. Test strength:
- "Most" ≠ "all." Priya might be in the minority who don’t benefit.
- The premise suggests but doesn’t guarantee the conclusion. 4. Weak argument.

What we did and why: We spotted the word "most," which weakens the argument. Strong arguments use "all" or "always."

1-Minute Recap

"Alright, CUET warriors—here’s your last-minute cheat sheet for Statement and Assumption, Conclusion, and Argument questions:

1. Assumptions are unstated but necessary. If the statement is true, what must also be true? Eliminate options that are already stated or irrelevant.
2. Conclusions must logically follow. If the premises don’t prove it, the conclusion is invalid—even if it’s true in real life.
3. Arguments are strong only if the premises guarantee the conclusion. Watch for words like ‘some,’ ‘most,’ or ‘may’—they weaken arguments.
4. Avoid traps: Don’t assume the conclusion is true, ignore extreme words, and never pick a stated fact as an assumption.
