Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Increase the number of features used in the model
Why it's wrong here
More features may not improve freshness if the model still uses stale data.

Add more training data from the past year
Why it's wrong here
Adding old data may dilute recent patterns.
- ✗
Use a deeper neural network architecture
Why it's wrong here
Deeper networks do not inherently address data staleness.
