The brain is a fascinating yet complex organ that controls thoughts, emotions, memories, touch, motor skills, vision, hunger, temperature, breathing and every process that regulates our body. Together with spinal cord that extends from it, they make up the central nervous system, or CNS.
The brain weighs about 3 pounds in the average adult, and is made of about 60% fat. The other 40% is a combination of water, protein, carbohydrates and salts. The brain itself is not a muscle. It contains blood vessels and nerves, including neurons and glial cells.
The brain is made up of several parts called lobes. The cerebellum is the size of a fist and it is located at the back of the head, between the temporal and occipital lobes. The outer portion contains neurons, and the inner area communicates with the cerebral cortex. The cerebellum is in charge of coordinating voluntary muscle movements and maintaining posture, balance and equilibrium.
The largest lobe of the brain is the frontal lobe. As its name suggests, it is located in the front of the head, and it is involved in personality characteristics, decision-making and movement. Some parts of the frontal lobe are also involved in smell recognition. The frontal lobe contains Broca's area, which is associated with speech ability.
The parietal lobe helps a person identify objects and understand spatial relationships, in terms of comprehending where a person is in relation to the objects surrounding them. Interpretation of pain and the sense of touch are also associated with the parietal lobe. It is located in the middle of the brain, and inside the parietal lobe is Wernicke's area, which helps the brain understand spoken language.
The occipital lobe is the back part of the brain that is involved with vision. The sides of the brain, temporal lobes are involved in short-term memory, speech, musical rhythm and some degree of smell recognition.

Question Focus: The diagram label at the front of the brain - we need the name of the lobe located at the front of the head
Correct Answer: C
Why this is correct: The diagram shows the front part of the brain. The passage clearly says the frontal lobe is located in the front of the head, so this label matches exactly.
Passage Reference: The largest lobe of the brain is the frontal lobe. As its name suggests, it is located in the front of the head, and it is involved in personality characteristics, decision-making and movement. Some parts of the frontal lobe are also involved in smell recognition. The frontal lobe contains Broca's area, which is associated with speech ability.
Common Mistake: Some students choose parietal lobe because it is another major lobe. But the passage says the parietal lobe is in the middle of the brain, not the front. This is a location confusion trap.
Paraphrasing: Passage: 'located in the front of the head' = Diagram: 'front part of the brain'
Tips: Always match the position on the diagram with location words like front, back, side, or middle in the passage.
Key Vocabulary:
- frontal = front
- lobe = part of the brain
Question Focus: The diagram points to the middle area of the brain - we need the lobe located in the middle
Correct Answer: G
Passage Reference: The parietal lobe helps a person identify objects and understand spatial relationships, in terms of comprehending where a person is in relation to the objects surrounding them. Interpretation of pain and the sense of touch are also associated with the parietal lobe. It is located in the middle of the brain, and inside the parietal lobe is Wernicke's area, which helps the brain understand spoken language.
Why this is correct: The diagram label is placed in the middle of the brain. The passage directly tells us the parietal lobe is located in the middle of the brain, so the answer fits perfectly.
Common Mistake: Students often choose frontal lobe because it is very important and described in detail. But frontal means front, not middle. This is a wrong section trap.
Paraphrasing: Passage: 'located in the middle of the brain' = Diagram: 'middle brain area'
Tips: Do not choose a word just because it has a long description. Focus on where it is.
Key Vocabulary:
- spatial = about space and position
- identify = recognize
Question Focus: The diagram shows the back of the brain related to vision
Correct Answer: H
Passage Reference: The occipital lobe is the back part of the brain that is involved with vision.
Why this is correct: The label points to the back of the brain. The passage clearly says the occipital lobe is the back part of the brain and is responsible for vision.
Common Mistake: Some students pick temporal lobes because they are on the sides near the back. But the passage says temporal lobes are on the sides, not the back. This is a location confusion trap.
Paraphrasing: Passage: 'back part of the brain' = Diagram: 'rear brain area'
Tips: When you see vision, think occipital. This is a very common IELTS pairing.
Key Vocabulary:
- occipital = back of the head
- vision = sight
Question Focus: The diagram shows the small rounded structure at the lower back of the brain
Correct Answer: B
Passage Reference: The cerebellum is the size of a fist and it is located at the back of the head, between the temporal and occipital lobes. The outer portion contains neurons, and the inner area communicates with the cerebral cortex. The cerebellum is in charge of coordinating voluntary muscle movements and maintaining posture, balance and equilibrium.
Why this is correct: The diagram shows a small structure at the back and bottom of the brain. The passage describes the cerebellum as being located at the back of the head, which matches the diagram.
Common Mistake: Students sometimes choose occipital lobe because it is also at the back. But the occipital lobe is a large lobe, not a small separate structure. This is a partial truth trap.
Paraphrasing: Passage: 'located at the back of the head' = Diagram: 'lower back brain part'
Tips: Look at size and shape in the diagram, not just location.
Key Vocabulary:
- coordinate = control together
- equilibrium = balance
Question Focus: The diagram label points to the sides of the brain
Correct Answer: I
Passage Reference: The sides of the brain, temporal lobes are involved in short-term memory, speech, musical rhythm and some degree of smell recognitio
Why this is correct: The diagram clearly marks the sides of the brain. The passage tells us that the temporal lobes are on the sides of the brain, so this is the correct label.
Common Mistake: Some students choose parietal lobe because it is near the top. But the question is about the sides, not the middle or top. This is a location confusion trap.
Paraphrasing: Passage: 'sides of the brain' = Diagram: 'left and right side areas'
Tips: Side view usually means temporal in brain diagrams.
Key Vocabulary:
- temporal = side area near temples
- rhythm = regular pattern
Question Focus: The diagram shows the long structure extending down from the brain
Correct Answer: D
Passage Reference: Together with spinal cord that extends from it, they make up the central nervous system, or CNS.
Why this is correct: The diagram shows something extending down from the brain. The passage says the spinal cord extends from the brain, so this label is correct.
Common Mistake: Students sometimes choose cerebrum because it sounds scientific. But the cerebrum is part of the brain, not something that extends downward. This is a context shift trap.
Paraphrasing: Passage: 'extends from it' = Diagram: 'long part going down'
Tips: Anything long and downward in a brain diagram is usually the spinal cord.
Key Vocabulary:
- extend = go down or continue
- CNS = central nervous system
General Tips:
- Diagram labels usually follow the passage order, so work from top to bottom.
- Always match location words like front, back, side, and middle.
- Use shape and size in the diagram to help you choose between similar options.
- Cross out each option after using it so you do not reuse it.
