Theory:

Human brain is capable of thinking and modifying algorithms based on situations.
 
Let us see some real-life situations, where we follow the instructions.
 
Situation I:
 
If you are riding a two-wheeler in the road, you have to stop the vehicle when indicating red light on a signal.
 
When "Green" light turns on, you can move from that place.

You are following the traffic rules made by the government.
 
This is the one way of following the instruction.
 
Situation II:
 
Father: Rahu, Go to the fruit shop and buy some fruits.
 
Rahu: Okay, dad.
 
Father: Come back within \(1\) hour.
 
Rahu: Sure dad.

Here, Rahu's father asked him to go to the shop. He followed his instruction and went to the shop.
 
This is another way of follow the instruction.
 
Situation III:
 
Question paper in an exam contains the following instructions.
 
1. Read the whole question paper and understand every question thoroughly and 15 minutes is allotted for this.
 
2. Answer all the questions in Part A. Each question carries \(1\) marks.
 
3. Answer any \(7\) questions in Part B. Each question carries \(2\) marks.
 
4. Answer any \(5\) questions in Part C. Each question carries \(5\) marks.
 
5. In Part D, every question has an internal choice. Answer any one alternative. Each question carries \(6\) marks.
