the logical question 16

寂寞的自由

8. Within 20 years it will probably be possible to iden-
tify the genetic susceptibility an individual may have
toward any particular disease. Eventually, effective
strategies will be discovered to counteract each such
susceptibility. Once these effective strategies are
found, therefore, the people who follow them will
never get sick.

The argument above is based on which of the follow-
ing assumptions?
(A) For every disease there is only one strategy that
can prevent its occurrence.
(B) In the future, genetics will be the only medical
specialty of any importance.
(C) All human sicknesses are in part the result of
individuals' genetic susceptibilities.
(D) All humans are genetically susceptible to some
diseases.
(E) People will follow medical advice when they are
convinced that it is effective.

the right answer is C, but the point that makes me puzzle is why the answer C must add the " in part"?
