Question

A graduate student is almost done with his dissertation when he is informed that twenty years ago someone did a very similar project and already demonstrated what he had hoped to be the first to discover. What basic step of the scientific method could have saved him from this problem?

Answer 1

Answer:Reviewing the literature

Step-by-step explanation:

Reviewing the literature could have saved him from this problem as the previous dissertation is present as references for future development or the study of an existing one.

A literature review is a scholarly paper, which includes the new findings with present knowledge, as well as theoretical and methodological development to a particular topic.
