Passage: Philosopher: In the 18th century, a paper on the absolutism of motion asserted that the change in position of one object over time could be measured without reference to the position of any other object.

Question: Which of the following methods or techniques does the philosopher use in his argument?
A. A.Use technical terms to convince others.
B. B.Relying on the authority of an expert to support a premise.
C. C.Reasonable when using experimental results to illustrate the mentioned position changes.
