Karl Popper suggested that scientists use "imaginative preconception," which means that successful scientists:

Question options :

A. do not need to do experiments to test their ideas.

B.only perform applied research.

C.do not keep records of experiments that fail.

D.often predict the outcome of experiments.

E.cannot predict the outcome of experiments

D.often predict the outcome of experiments.

Explanation:

Karl Popper's Imaginative preconception is the idea that one could know or imagine or maybe have a good guess of what the outcome of an experiment would be. In other words a scientist will often hypothesize from observation of what the outcome of an experiment would be without testing and ascertaining truth through experimentation yet. Therefore the scientist combines knowledge and imagination in arriving at the fact or truth in his research or investigations
