Answer:
The correct option is Identical
Step-by-step explanation:
What makes science unique from other fields of study is that when an experiment is conducted and the procedures of the experiment is strictly duplicated in any part of the world, the results of the experiments must be similar/identical to show that the results are valid. Hence, the groups of students, despite performing this experiment in different parts of the world, must be the same/identical if the results are indeed true/valid.
