Match the hypothesized mechanisms for improvements in cognitive functioning with physical activity to their description. 

Explain the difference between overfitting and underfitting in machine learning. Provide an example scenario for each and briefly describe how you might address each issue when building a model.

In a decision tree, a node is split based on a feature that provides the greatest [box1] in impurity, measured by metrics such as Gini or Entropy.

Describe how the k-Nearest Neighbors (KNN) algorithm makes predictions. What are some of the limitations of KNN, and how can the value of “k” influence model performance?

The difference between fit() and predict() in scikit-learn is that fit() is used to [box1] the model to training data, while predict() is used to make [box2] on new data.

 Stratified sampling in cross-validation is important in classification problems to maintain the original distribution of the [box1] variable across folds.
