Some materialist empiricists are either libertarians or hard determinists. But no empiricist is a hard determinist. So some materialists are libertarians.
-Which of the following claims can also be derived from the premises of this argument?
A) (∃x)[(Mx • Ex) • (Lx • ∼Dx)]
B) (∀x)∼Dx
C) (∀x)Ex
D) (∃x) ∼Lx
E) (∀x)∼Lx

The argument states that some materialists are libertarians and that no empiricist is a hard determinist. This allows us to infer that there exists at least one person who is both a materialist (M) and a libertarian (L), and is not a hard determinist (∼D). This can be represented as (∃x)[(Mx • Ex) • (Lx • ∼Dx)], which is option A.
