In
2013
,
an
____________________
swimmer
named
Diana
Nyad
became
the
first
person
to
swim
from
Cuba
to
Florida
without
using
a
shark
cage
.
Nyad
had
unsuccefully
attempted
the
177
-
kilometer
swim
several
times
before
,
but
at
age
64
,
she
finally
completed
it
.
The
swim
____________________
Nyad
to
be
in
the
water
for
nearly
53
hours
.
A
35
-
person
team
came
with
her
,
and
(
unlike
her
previous
attempts
)
she
wore
a
special
suit
and
mask
to
keep
jellyfish
off
her
skin
.
Some
suggested
this
equipment
____________________
her
performance
,
though
Nyad
claimed
it
actually
slowed
her
down
.
What
____________________
this
succesful
attempt
from
Nyad's
four
previous
attempts
?
Importantly
,
the
____________________
she
made
to
her
equipment
helped
-
she
was
previously
stung
many
times
by
jellyfish
.
But
experts
believe
the
main
difference
was
Nyad's
mental
determination
,
since
her
struggle
was
just
as
much
____________________
as
physical
.
Her
determination
wa
so
strong
that
even
though
she
felt
sick
for
much
of
the
journey
,
she
never
gave
up
.
