Answer:
The answer is deductive argument
Explanation:
In deductive reasoning, we begin with premises that are assumed to be true. We then determine what else would be true given that the premises are true.
If we look at this problem, premise 1 is assumed to be true. Premise 2 is also true. This absolutely and logically prove that the conclusion is true as well. This is the process of deduction. Note that while both of the premises provide an absolute proof for the conclusion to be true, premises 1, in itself, remain unproven and unprovable.
