it has no clear referrant.. it can refer to bacterium or disease

Despite gerally uses for contrast statements.

E is the best.

(A) though it spares
(B) where it spares
(C) despite sparing
(D) when sparing
(E) while sparing

choose E
my reasoning: the sentence logically implies a turn in meaning here, so B/D out
C looks awkward, out

A "it" has no clear referent

Hi mates,

IMO A

The sense of the sentence needs a conjunction that changes the flow of the argument. Also, "it" refers to "the disease it causes, listeriosis"

Another reason is //ism: the disease it causes (here it refers to bacterium) afflicts [...] though it spares [...] (the second "it" refers to disease"

OA and Source?

Cheers

Is not listeriosis the clear antecedent of "it"??
I am with A.
I dont like the "while" in E.
