To Warrant the Use of Expert Testimony, Two Elements Are

To warrant the use of expert testimony, two elements are required. One of these is:

A) the subject of the inference must be so distinctly related to some science, profession, business, or occupation as to be beyond the knowledge of the average person.
B) the expert must be one who is well-educated at a college or university, such as a physician or a scientist.
C) the jury must find that a witness has observed the original facts of the case.
D) the expert must be able to give an opinion with absolute certainty.
