*Question*
But the more computing power that goes into the model and the care with which the scientists construct the model can increase the chances that a model will be accurate.  Stephanie had designed a machine learning algorithm to help predict earthquakes. Today, her new supercomputer arrived and she will soon run the algorithm on the less powerful computer. The new computer will increase or decrease the accuracy of the model's predictions?
**Answer**
decrease
