Answer
We can suck water up a straw to a height of $1.02~m$
Work Step by Step
The gauge pressure is 10 kPa. We can calculate the height difference $h$ for this gauge pressure:
$\rho gh = 10~kPa$
$h = \frac{10~kPa}{\rho ~g}$
$h = \frac{10~\times 10^3~N/m^2}{(10^3~kg/m^3)(9.80~m/s^2)}$
$h = 1.02~m$
We can suck water up a straw to a height of $1.02~m$.
