Which of the following is a feature in the teacher view of Google Expeditions?

In the teacher view of Google Expeditions, sample questions serve as an essential feature. They provide teachers with the ability to guide discussions and enhance the learning experience by prompting students to think critically about the content being explored. This feature enables educators to stimulate engagement and facilitate deeper understanding by asking students relevant questions as they navigate through the virtual environment. Sample questions can also help reinforce lessons and provide a more structured approach to the exploration, allowing students to connect what they see with their learning objectives.

While other options, such as interactive feedback forms and video conferencing tools, provide useful functionalities in the educational context, they are not specific features available within the Expeditions platform itself. Student performance tracking may also be essential, but it does not directly align with the tools and experiences created within Google Expeditions, which primarily focuses on immersive exploration rather than direct assessment or real-time analytics.
