Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the questions from 35 to 42.
One of Aesop's fables describing a thirsty crow which was able to drink from a half-full pitcher after raising the water level by adding pebbles may have had a basis in real life.
Scientists have found that rooks - a member of the crow family - were able to figure out how to raise the water level in a laboratory container by dropping stones inside to retrieve a tasty worm floating on the surface.
The only other animal shown to be able to perform the same task is the orang-utan, which was able to grasp a floating peanut by spitting water into a tube. Scientists believe the demonstration shows that, in many respects, rooks and crows have comparable intelligence to primates when it comes to the use of tools.
"We have performed a large number of studies on both corvids (members of the crow family) and apes, and have found that the crow's performance is on a par or often superior to apes. However, it is not particularly useful to say that one species is more or less intelligent than another because often the playing fields aren't even," said Nathan Emery of Queen Mary, University of London, who carried out the work with Christopher Bird at Cambridge.
"This (study) suggests that they can not only think through complex problems requiring the use of tools, but imagine the consequences of their actions without trial-and-error learning, and create novel solutions to these problems that have never been encountered before," Dr Emery said.
"This has only ever been shown in the great apes and humans and is more surprising because the birds have brains the size of walnuts and these birds do not use tools in the wild."
"We believe that intelligence in rooks and other crows evolved primarily to solve social problems, as almost all crow species live in large social groups, but they also mainly form pair bonds, like human marriages, and some of their cognitive abilities appear to have evolved to help them predict what others are going to do next - so-called mind reading," Dr Emery said.
"This may have developed into understanding about the psychological properties of unseen forces that are important in using and making tools."
