The Intelligence Of Corvids Ielts Reading Answers Extra Quality Work — Top & Pro
To achieve a high band score, you need to be able to spot 'distractors'—words or phrases designed to trick you into choosing the wrong answer. Question 10 is a perfect example. The statement says, 'Corvids can be found on every continent.' The passage says, '...on every continent except Antarctica'. The phrase is the distractor. The test-maker is checking if you read carefully enough to catch this small but crucial detail. In your practice, always highlight such limiting words (like 'always', 'never', 'all', 'only', 'except') in both the statement and the passage. They are often the key to getting the answer right.

: When the same researchers walked around without the masks, the crows showed no reaction, confirming they were specifically identifying the face as the threat. The phrase is the distractor
Researchers have replicated the ancient fable where a thirsty crow drops stones into a pitcher to raise the water level. In modern experiments, rooks and crows consistently chose heavier objects over light ones and solid objects over hollow ones to displace water and reach a floating reward. This demonstrates an understanding of that human children typically don't master until age five or seven. IELTS Reading Practice: Sample Questions

The neurological foundation of corvid intelligence lies not in the size of their brains in absolute terms, but in their encephalization quotient (EQ) and brain structure. While a crow's brain is roughly the size of a human thumb, its brain-to-body mass ratio is remarkably similar to that of a chimpanzee. More importantly, corvids lack the cerebral cortex found in mammals, which was long thought to be the mandatory engine for complex thought. Instead, corvids possess an densely packed cluster of neurons known as the nidopallium caudolaterale (NCL). This area acts as the avian equivalent of the prefrontal cortex, processing executive functions, working memory, and decision-making with extraordinary efficiency. Paragraph C
The amount of brain mass related to the total body mass of a given animal.
Even more astonishing is how corvids protect their caches from thieves. If a common raven (Corvus corax) notices that another bird is watching it bury food, it will alter its behavior. The caching raven will fake a burial, hiding the food in its throat pouch, and fly off to bury it in a secret location when the onlooker is out of sight. This behavior suggests that ravens possess a "Theory of Mind"—the rare cognitive ability to attribute mental states, such as knowledge or intent, to others. The raven understands that the observer knows where the food is, and actively takes steps to deceive them.
