How are the driver and navigator roles assigned in a pair programming scenario?(1 point) Responses The driver is always the senior member of the team, and the navigator is an apprentice who may grow into a driver. The driver is always the senior member of the team, and the navigator is an apprentice who may grow into a driver. The driver’s and the navigator’s positions are specifically hired for based on each programmer’s existing skills. The driver’s and the navigator’s positions are specifically hired for based on each programmer’s existing skills. The driver is the junior member of the team, and the navigator acts as their mentor. The driver is the junior member of the team, and the navigator acts as their mentor. Each programmer is either the driver or the navigator randomly at the start of each session and switch roles frequently.

In a pair programming scenario, the roles of driver and navigator are typically assigned based on the dynamic of the team rather than fixed hierarchies or roles. Each programmer can take turns being the driver or navigator, often switching roles frequently to promote collaboration and learning. Therefore, the most aligned response would be:

"Each programmer is either the driver or the navigator randomly at the start of each session and switch roles frequently."

This approach encourages knowledge sharing and allows both members to contribute effectively in both roles.

Why is pair programming an efficient development method despite requiring two developers to work at a shared station?(1 point) Responses It requires twice as much time as the traditional approach. It requires twice as much time as the traditional approach. It results in a code that initially requires fewer corrections, and developers are often happier and more confident when using this process. It results in a code that initially requires fewer corrections, and developers are often happier and more confident when using this process. It often leaves developers aggravated and frustrated. It often leaves developers aggravated and frustrated. It requires twice as many personnel to work on a given project raising costs and slowing development. It requires twice as many personnel to work on a given project raising costs and slowing development.

The most appropriate response regarding why pair programming is an efficient development method, despite requiring two developers to work at a shared station, is:

"It results in a code that initially requires fewer corrections, and developers are often happier and more confident when using this process."

Pair programming fosters collaboration, leading to better code quality and fewer bugs, while also enhancing team morale and confidence in the development process.
