In India aU children are supposed to go to school
between the ages of six and 14. In fact in the coun-
tryside it is very difficult for young children to get
an education because the government has failed to
build enough schools, and also because transport
is difficult, and children need to take the bus to get
to school. There are few buses so most children go
on foot. On top of aU these problems, many par-
ents never went to school themselves, so they don 't
expect their children to go. Many parents are also so
poor that they don't let their children gQ to school,
but prefer to send them to work instead, because
they need the money. Children from richer families,
on the other hand, often live near good schools, and
their parents encourage them to pass their exams so
that they can get good jobs.
