Try a question

A team removes the gender column from its hiring data set, but the model still favours one gender. What is the most likely cause?
A. The model was deployed to the wrong region
B. The temperature parameter is set too high
C. Other features act as proxies for gender
D. The training data set was encrypted at rest
Show answer
Answer: C. Dropping a sensitive attribute is not enough for fairness. Correlated features (proxies) can carry the same signal. Teams should measure outcomes per group and mitigate, for example by rebalancing data or adjusting thresholds.
Harbourline Clinics wants an AI assistant that suggests triage levels. The team must make sure the assistant behaves predictably when it receives unusual or incomplete symptom descriptions. Which principle does this requirement address?
A. Transparency
B. Inclusiveness
C. Accountability
D. Reliability and safety
Show answer
Answer: D. Reliability and safety covers rigorous testing, handling edge cases, monitoring in production and failing safely. High-stakes domains such as health need it most.
