**First question: Statement most accurately describing the swimmer in the pool according to Newton’s Third Law.**
The correct choice is:
- **the swimmer exerts a force on the wall; the wall exerts an equal and opposite force on the swimmer.**
This statement embodies Newton's Third Law of Motion, which states that for every action, there is an equal and opposite reaction. When the swimmer pushes off the wall with her legs, she exerts a force on the wall, and in return, the wall exerts an equal and opposite force that propels her forward.

**Second question: Situation showing a non-contact force changing the speed of an object.**
The correct choice is:
- **A nail rolls off the edge of a roof and falls to the ground.**
This scenario demonstrates gravity, a non-contact force, acting on the nail as it falls. The other options involve contact forces directly imparting motion or changing speed.
---
**Third question: Describe what happened to Francine.**
The correct responses to complete the statement would be:
A(n) **external** force stopped the bike, but Francine’s body continued forward due to **inertia**.
Inertia is the tendency of an object to maintain its state of motion unless acted upon by an external force, which explains why Francine continued to move forward even after the bike stopped.
