  Random groups of density d<\frac{1}{2} are infinite hyperbolic, and of
density d>\frac{1}{2} are finite. We prove the existence of a uniform
quantifier elimination procedure for formulas of minimal rank (probably the
superstable part of the theory). Namely, given a minimal rank formula V(p), we
prove the existence of a formula \varphi(p) that belongs to the Boolean algebra
of two quantifiers, so that the two formulas V(p) and \varphi(p) define the
same set over the free group F_{k} and over a random group of density
d<\frac{1}{2}. We conclude that any given sentence of minimal rank is a truth
sentence over the free group F_{k} if and only if it is a truth sentence over
random groups of density d<\frac{1}{2}.
