Reasoning Ability - Statement & Assumption

Statement: "Turn off the lights when leaving a room."
Assumptions:
1️⃣ Leaving lights on wastes electricity.
2️⃣ People sometimes forget to switch lights off when they leave.
Which assumption(s) is/are implicit?

AOnly 1

BOnly 2

CBoth 1 and 2

DNeither 1 nor 2

Step-by-Step Solution

Step 1: Consider the nature of the instruction
The command is short and habit-oriented; it targets behaviour rather than restating a well-known fact.
Step 2: Evaluate assumptions
Assumption 2 (people sometimes forget) is implicitly the reason for the reminder—if everyone always remembered, the reminder would not be needed. Assumption 1 (waste occurs when lights are left on) is generally true but not the explicit motivating assumption in short habit reminders; the central point here is correcting forgetful behaviour, so Only 2 is the better implicit assumption in this phrasing.
Final Answer:
Only 2 is implicit. → Option B
Quick Check:
Reminders often assume a habit problem (forgetting) more than they restate obvious facts ✅

Quick Trick: Short habit reminders usually assume a behavioural lapse (forgetfulness).

Common Mistakes:

Overstating which background fact is being assumed versus what behaviour is targeted.
