   A city deploys an AI system to screen job applications and rank candidates. After a year, the city notices that applicants from certain neighborhoods are consistently ranked lower, even when qualifications are similar. What is the most likely cause and the best first step to address it?

   • AThe model is not receiving enough data; the city should add more unlabeled data.
   • BThe training data contained historical biases that the model learned; the city should audit the data and model for bias.
   • CThe AI is intentionally discriminating; the city should replace it with a simpler rules-based system.
   • DThe model is overfitting to the training data; the city should reduce the number of features.

   An AI team is training a model to detect fraudulent transactions. The dataset has 99% legitimate transactions and 1% fraudulent ones. The model achieves 99% accuracy but fails to catch most fraud. What is the most likely cause and the best remedy?

   • AThe model is not receiving enough data; the team should collect more data without regard to class balance.
   • BThe model is overfitting to the training data; the team should reduce the number of features.
   • CThe dataset is imbalanced, so the model learns to predict the majority class; the team should use techniques like oversampling the minority class or using a different evaluation metric.
   • DThe model is underfitting because it is too simple; the team should use a more complex algorithm.
