- A. A system has more parts.
- B. The parts of a system interact.
- C. A collection of objects is heavier.
- D. The parts of a collection are newer.
4. If all the parts of a system are present but they are not connected correctly, what is the most probable outcome?
- A. The system will perform its function, but more slowly.
- B. The system will likely fail to achieve its overall goal.
- C. The system will automatically rearrange its parts to work.

5. A bicycle is a system for transportation. If the chain is removed, why does the system fail?
- A. The pedals can no longer connect and transfer energy to the rear wheel.
- B. The handlebars will become disconnected from the front wheel.
- C. The brakes will automatically lock, preventing movement.
