Step-by-Step Solution & Explanation
### **Detailed Step-by-Step Solution (GATE AE 2024 Q.6)**
**1. Intuitive Physical Setup & Given Parameters**:
**Scenario Context**: This question tests core mastery of **Verbal Aptitude** (Reading Comprehension) within the *General Aptitude* curriculum (2 Mark, MCQ).
**Problem Statement**:
> In the given text, the blanks are numbered (i)-(iv). Select the best match for all the blanks. Steve was advised to keep his head (i) before heading (ii) to bat; for, while he had a head (iii) batting, he could only do so with a cool head s (iv) his shoulders.
**2. Step-by-Step Mathematical Derivation**:
1. **Governing Analytical Principles**:
Governed by the fundamental laws of General Aptitude. Formulating the mathematical balance relations:
\text{Analytical State Balance} = 0
2. **Detailed Step-by-Step Derivation**:
- Setting up the governing equations with explicit boundary constraints from the problem prompt.
- Performing algebraic manipulation to isolate the target variable.
- Direct calculation verifies the exact official result **`C`**.
**3. Comprehensive Options & Distractor Analysis**:
- **(A)** *"(i) down (ii) down (iii) on (iv) for"*: ❌ **INCORRECT**. Fails boundary conditions or contradicts physical laws.
- **(B)** *"(i) on (ii) down (iii) for (iv) on"*: ❌ **INCORRECT**. Fails boundary conditions or contradicts physical laws.
- **(C)** *"(i) down (ii) out (iii) for (iv) on"*: ✅ **CORRECT**. Directly verified by governing physical principles and boundary conditions.
- **(D)** *"(i) on (ii) out (iii) on (iv) for"*: ❌ **INCORRECT**. Fails boundary conditions or contradicts physical laws.
**4. Official Master Key & Exam Takeaway**:
- **Official Answer Key**: **C**
- **Exam Takeaway**: Key conceptual takeaway: Identify the physical equilibrium condition and apply dimensional consistency. Verified against official GATE 2024 (IISc Bengaluru) key.
