Answer 2

Answer:

Experimental investigations are the best type of scientific investigation to demonstrate cause-and-effect relationships because they allow the investigator to actively manipulate variables and control conditions.The independent variable can be isolated and manipulated,producing a change (or no change) in the dependent variable.This change can be measured to gather evidence to support or refute the cause-and-effect relationship.
