  This note answers a question of Kechris: if $H<G$ is a normal subgroup of a
countable group $G$, $H$ has property MD and $G/H$ is amenable and residually
finite then $G$ also has property MD. Under the same hypothesis we prove that
for any action $a$ of $G$, if $b$ is a free action of $G/H$, and $b_G$ is the
induced action of $G$ then $\CInd_H^G(a|H) \times b_G$ weakly contains $a$.
Moreover, if $H<G$ is any subgroup of a countable group $G$, and the action of
$G$ on $G/H$ is amenable, then $\CInd_H^G(a|H)$ weakly contains $a$ whenever
$a$ is a Gaussian action.
