  We show that, in the context of the two-field measure theory, any k-essence
model leads to the existence of a fluid made of non-relativistic matter and
cosmological constant that would explain the dark matter and dark energy
problem at the same time. On the other hand, kinetic gravity braiding models
can lead to different behaviors, such as phantom dark energy, stiff matter, and
a cosmological constant. For stiff matter, there even exists the case where the
scalar field does not have any effect in the dynamics of the Universe.
