  Quasiperiodic oscillations (QPOs) have been observed in the power-density
spectra of some low-mass X-ray binaries(LMXB) containing a black hole. The two
major groups of QPOs -- low-frequency and high-frequency -- have rather
different properties. That is why they are usually studied separately. In the
literature one can find a large number of models for the high-frequency QPOs
but not so many for the low-frequency ones. HF QPOs have attracted significant
research efforts due to their potential to provide indispensable information
for the properties of the black hole, for its accretion disc and for strong
field gravity in general. However, in order to interpret the data for the HF
QPOs of the observed objects we have to fix a model. Here we propose a simple
test which could allow us to sift the models. The test is based on five rather
general assumptions concerning the nature of the central object in black-hole
binaries and the mechanism for the generation of the LF QPOs observed in the
PDS of such objects. In other words we combine facts that we know about the LF
and the HF QPOs of several objects and search for conflicts. As a result we
single out a model for the HF QPOs -- the 3:2 nolinear resonance model. As a
byproduct of this study we propose loose constraints on the mass of the LMXB H
1743-322.
