Question

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): Escalators are preferred by users for vertical circulation in a mall than elevators.
Reason (R): The speed of elevator is much lesser than that of escalator. In the light of the above statements, choose the most appropriate answer from the options given below:

• A. Both (A) and (R) are correct and (R) is the correct explanation of (A)
• B. Both (A) and (R) are correct but (R) is not the correct explanation of (A)
• C. (A) is correct but (R) is not correct
• D. (A) is not correct but (R) is correct

Hint:

Difference between elevators and escalators:
• Elevator $\rightarrow$ Faster vertical transport with waiting time
• Escalator $\rightarrow$ Continuous pedestrian movement Escalators are preferred in malls because they efficiently handle high pedestrian traffic.

Answer 1

The Correct Option is C

Concept: Vertical circulation systems in buildings include:
• Stairs,
• Elevators,
• Escalators,
• Ramps. In shopping malls and commercial complexes, escalators are commonly preferred because they allow continuous passenger movement and improve circulation efficiency.

Step 1: Analyze Assertion (A).
Escalators are generally preferred in malls because:
• They provide continuous movement,
• They handle large pedestrian flow efficiently,
• Users can easily move between floors without waiting. Hence, Assertion (A) is correct.

Step 2: Analyze Reason (R).
The statement says: \[ \text{The speed of elevator is much lesser than that of escalator.} \] This statement is incorrect because elevators usually move faster vertically than escalators. However, elevators involve waiting time and limited passenger capacity compared to escalators. Therefore, Reason (R) is incorrect.

Step 3: Choose the appropriate option.
Since Assertion (A) is correct but Reason (R) is incorrect, the correct answer is: \[ {(A)\; \text{is correct but}\; (R)\; \text{is not correct}} \]
