  The fact that analyses of semi-inclusive deep inelastic scattering suggest
that the polarized strange quark density $\Delta s(x) + \Delta \bar{s}(x)$ is
positive in the measured region of Bjorken x, whereas all analyses of inclusive
deep inelastic scattering yield significantly negative values of this quantity,
is known as the "strange quark polarization puzzle". We have analyzed the world
data on inclusive deep inelastic scattering, including the COMPASS 2010 proton
data on the spin asymmetries, and for the first time, the new extremely precise
JLab CLAS data on the proton and deuteron spin structure functions. Despite
allowing in our parametrization, for a possible sign change, our results
confirm that the inclusive data yield significantly negative values for the
polarized strange quark density.
