Those
ramps
,
called
curb
cuts
,
are
now
very
common
.
However
,
sidewalks
and
public
spaces
were
not
always
accessible
to
people
with
disabilities
.
During
the
____________________
when
veterans
returned
from
World
War
II
,
many
came
home
needing
wheelchairs
.
They
were
unable
to
enter
colleges
,
banks
,
or
businesses
because
of
stairs
or
high
curbs
.

Further
propulsion
of
the
movement
came
from
the
design
world
.
Ronald
Mace
,
an
architect
and
designer
,
provided
____________________
through
a
set
pf
principles
known
as
universal
design
.
These
ideas
are
used
to
make
public
spaces
easily
accessible
for
everyone
.

Accessible
public
spaces
have
only
become
possible
through
federal
laws
,
changes
in
street
design
,
and
the
hard
work
of
activists
.
The
original
____________________
of
the
activists
was
to
help
one
group
of
individuals
.
However
,
curb
cuts
ended
up
making
life
safer
and
smoother
for
all
people
!
