Why are simulations used in predictive studies?

A. they allow for multiple scenarios
B. they collect data
C. they pick the correct scenario
D. they interpret data

A. they allow for multiple scenarios

Simulations are used in predictive studies because they allow researchers to test out various scenarios and analyze the potential outcomes without needing to conduct expensive or time-consuming real-world experiments. This helps researchers make more informed decisions and predictions based on a range of possible outcomes.
