READ THE PASSAGE AND ANSWER THE QUESTION THAT FOLLOWS: Dolphins are regarded as the friendliest
creatures in the sea and stories of them helping drowning sailors have been common since Roman times.
The more we learn about dolphins, the more we realize that their society is more complex than people

protect the weakest in the community, as we do. Some scientists have suggested that dolphins have a
language but it is much more probable that they communicate with each other without needing words.
Could any of these mammals be more intelligent than man? Certainly, the most common argument in
favour of man's superiority over them that we can kill them more easily than they can kill us is the least
satisfactory. On the contrary, the more we discover about these remarkable creatures, the less we appear
superior when we destroy them. ONE CAN INFER FROM THE READING THAT ----
Select one:
a. dolphins have skills that no other living creatures have such as the ability to think
b. dolphins have some social traits that are similar to those of humans
C. communication is the most fascinating aspect of the dolphins
d. it is not usual for dolphins to communicate with each other
e. dolphins are quite abundant in some areas of the world
