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.
Which of the following can be inferred from the passage?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Some work of the body goes on without our thinking about it
The passage says that “The brain automatically controls breathing, heartbeat, digestion”.
- Automatically means on its own, without any effort from us.
- We do not have to think about breathing or about our heartbeat. They go on by themselves.
- So some work of the body happens without our thinking about it.
Why the Other Options are Incorrect?
Option 1: Each organ of the body does its work on its own — Incorrect. Contradicted: The passage says the organs “work together and are controlled by the brain”. They do not work alone.
Option 3: Skin keeps germs out but lets water into the body — Incorrect. Contradicted: The skin keeps out both. The passage says “It keeps water and harmful germs out”.
Option 4: The muscles of the body lie inside the bones — Incorrect. Contradicted: The passage places the muscles “Between the skeleton and the skin”. They lie over the bones, not inside them.
