What type of device must teams bring for their PSA presentation?

The correct answer is that teams must bring a personal electronic device for their PSA presentation. This is critical because a personal electronic device like a laptop or tablet is essential for accessing and presenting the content of the PSA during the event. It allows teams to showcase their digital media effectively, whether it be through slides, videos, or other multimedia elements that they have prepared. Teams typically rely on their own devices to ensure compatibility with the software and files they’ve chosen for their presentation, which is often vital in maintaining the integrity of their work during the evaluation.

In contrast, a projector would be a helpful tool for displaying visuals to a larger audience but is not something teams are specifically required to bring. Calculators are unrelated to the essential components of a PSA presentation and do not contribute to the presentation's delivery or content. A digital camera might be useful for capturing moments or creating visuals, but it does not directly support the presentation format needed for a PSA event. Thus, the necessity of a personal electronic device aligns perfectly with the requirements for delivering a successful and engaging public service announcement.
