Explanation : In deductive arguments conclusions are certain
provided the premises are true.
In inductive arguments, even if all of the given
premises are true, there is a possibility for
the conclusion to be false.
In analogical arguments, two similar things
are compared/associated, such that, what
is true of one is also true of the other. So,
conclusion may not be conclusively drawn
from the premises.
Both demonstrative and non-demonstrative
processes use analogy to prove/justify
knowledge; and to obtain new knowledge,
respectively. So, the conclusion cannot be
drawn conclusively from the given premises.
