I
think
a
lot
of
things
____________________
____________________
in
2050
.
India
will
____________________
China
as
the
first
largest
economy
in
the
world
,
but
the
country
will
____________________
many
problems
with
its
demographics
.
The
world
will
also
____________________
a
lot
of
problems
with
the
pollution
and
the
climate
changing
.
We
will
____________________
to
find
other
resources
,
because
____________________
will
____________________
more
than
nine
billion
people
on
Earth
in
____________________
.
We
will
also
____________________
to
build
spaceships
to
travel
to
the
Moon
and
to
Mars
,
because
we
will
have
to
take
resources
from
these
places
.
