Expression of Ideas practice question
While researching a topic, a student has taken the following notes:
- A honeybee's brain contains about one million neurons.
- A human brain contains about 86 billion neurons.
- Honeybees can learn to recognise individual human faces.
- Honeybees communicate the location of flowers to one another through a dance.
The student wants to emphasise how much smaller a honeybee's brain is than a human's. Which choice most effectively uses relevant information from the notes to accomplish this goal?
- A. A honeybee's brain contains about one million neurons, compared with roughly 86 billion in a human brain.Correct
- B. Honeybees can recognise human faces and communicate through a dance.
- C. A honeybee's brain has about one million neurons, which is why it can recognise faces.
- D. A human brain contains about 86 billion neurons.
Answer: A. A honeybee's brain contains about one million neurons, compared with roughly 86 billion in a human brain.
A difference in size needs both sizes side by side. Choice A puts the bee's one million next to the human's 86 billion.
Why the other answers are wrong
- B. Honeybees can recognise human faces and communicate through a dance.
- These are things bees can do, not the size of their brains.
- C. A honeybee's brain has about one million neurons, which is why it can recognise faces.
- Only the bee's figure appears, so there is no comparison — and the 'which is why' adds a cause the notes don't give.
- D. A human brain contains about 86 billion neurons.
- Only the human figure appears; the bee's brain isn't mentioned.
