Answer:
Cumulative.
Step-by-step explanation:
Dr. Morabian’s work inspired by studies published 10 years before he got his doctorate, demonstrates that science is cumulative. The concept of science as cumulative refers to a progressive approach to problems. If the problems have not been solved, other scientists from new generations can address it in some other way based on what has been found earlier. Dr. Morabia read these studies to be guided by them in the new research he is conducting.
