From the passage, it is quite obvious that the keepers described ----.

In one part of the Nairobi National Park there is a
nursery for baby elephants whose mothers have
been killed. There are at least two African keepers
for each baby elephant, and a strong feeling of love
soon develops between them. The keepers spend all
day out in the park with the young elephants, helping
them to learn which foods are best to eat and to
become confident among the sounds and smells of
nature just as their natural mothers would have done.
Each evening they return to the nursery. And, after a
feed of milk, the young elephants settle down beside
their favourite keepers and presently fall asleep.
