Answer 2

2. observable

Step-by-step explanation:

The scientific method relies on a scientist being able to study an occurrence and understand it. So, all the occurrences must be observable; otherwise, they cannot be studied. If the patterns are observable then one can follow the scientific method and experiment with the different variables. All science depends on the observable world and the people that study it.
