Read the passage and answer the following question.
The human body is a wonderful machine. It performs several functions without rest from birth. The main organs of the human body are the lungs, heart, kidneys, liver and brain. These organs work together and are controlled by the brain. The body has trillions of living cells of about two hundred different types. These cells include neurons (nerve cells) and the cells of glands. Hormones and enzymes are produced and secreted by these glands. Cells doing similar jobs are grouped to form tissues. The tissues group together in a special manner to form organs.
The human body is covered by the skin. Skin is a flexible covering that protects the body. It keeps water and harmful germs out. The body’s strong internal framework (skeleton) is made of 206 bones. These are connected at joints, such as in the legs. These joints help us to move. Between the skeleton and the skin, there are more than 600 muscles. Nerves spread from the brain to all parts of the body. They carry signals in the form of tiny electrical impulses. The sense organs, namely the eyes, nose, ears, tongue and skin, pass messages to the brain through nerves. Nerves also take instructions from the brain to the muscles. The brain automatically controls breathing, heartbeat, digestion, etc. When we grow old, the skin becomes wrinkled and less elastic. The joints become stiff, the muscles lose their strength and the bones become weak.
The human body is the most valuable gift of God to human beings. A healthy body contains a healthy brain. As such, it is very important to take care of our bodies. For this, regular exercise, control over eating habits, cleanliness of body and discipline are essential in daily life.
What is the main purpose of the passage?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → To explain how the parts of the body work together and why we should take care of it
Most of the passage describes the parts of the body.
- It moves from cells and tissues to organs, skin, bones, muscles and nerves. It says the organs “work together” under the brain.
- The last part then gives the advice. It says “it is very important to take care of our bodies”.
- Option 1 covers both these parts.
Why the Other Options are Incorrect?
Option 2: To prove that the brain is more important than all the other organs — Incorrect. Overstated: The passage says the brain controls the organs. It does not compare the brain with the other organs or try to prove anything.
Option 3: To describe how the body becomes weak in old age — Incorrect. Too narrow: Old age comes up in only two lines. The passage is about the whole body.
Option 4: To warn readers about the germs that attack the body — Incorrect. Too narrow: Germs are named only once, where the passage says the skin keeps them out. The passage gives no warning about them.
