Read the passage and answer the questions that follow.
What do we mean when we say someone
is intelligent? Intelligence is the ability
to think on the basis of the information
available and solve problems. After
human beings, dolphins are the next
most intelligent creatures on earth. Like
human beings, dolphins have large brains
when compared to their body size. Since
dolphins cannot take an IQ (Intelligence
Quotient) test to measure their intelligence,
we measure it by comparing their brain
size with their body size. This is called
EQ (Encephalisation Quotient). Human
EQ is 7.0, while a dolphin’s is 4.2 and
the chimpanzees’, whales’ and elephants’
is 1.8 to 2.4. Dolphins come closest to us
in intelligence.
For example, Kelly, the dolphin, is indeed
very clever. She lives in the Institute of
Marine Mammal Studies in Mississippi.
Dolphins there are taught to keep the pools
clean. They bring any litter that falls into
the pools to the trainers. Their reward is a
fish. Kelly has taken her learning one step
further. The intelligent mammal picks up
pieces of paper people throw, and hides
them at the bottom of the pool. She tears
off a piece of paper and brings it to the
trainer to get a reward. Fish-rewards are
given whether a dolphin brings a small
piece or a big one. She has trained the
humans! A large gull flew into the pool
one day. The intelligent Kelly grabbed it
and gave it to the trainers. It was a large
gull so the trainers gave Kelly lots of fish.
A new idea came to Kelly. Kelly began
saving and using one or two of the fish
she got very intelligently. She broke the
fish into pieces and spread them on the
pool surface instead of eating it.
Pieces of fish attracted more gulls. The
gulls were immediately caught and given
to the trainers for more fish-rewards! Kelly
has now trained her family and friends in
the pool. Gull baiting is now very common.
The dolphins' intelligence has surprised
everyone.
The purpose of the passage is to _______.
