What should you anticipate, if you want to overtake?

You answered correctly because all three points are important to consider when overtaking in this situation.

1. The cyclist's riding may be unsafe due to slippery road conditions, so you must be ready for sudden or unpredictable movements.
2. The road is covered with snow, which extends stopping distances. You need more time and space to brake safely.
3. Snow and ice increase the risk of skidding, especially during maneuvers like overtaking, so you should drive carefully and avoid sudden steering or braking.

This means when overtaking on snowy or icy roads, always anticipate that the cyclist might not ride steadily, plan for longer braking distances, and be prepared for loss of traction to ensure safe overtaking.
