What to Do When the Presentation Computer Lacks a Sound Card

A.

The most appropriate solution to maintain the delivery method intended by the course designers when the presentation computer has no sound card is to ask the IT staff to install a sound card on the computer before the class starts (option A).

Explanation: The course material includes a video clip with sound, indicating that the designers intended for the video to be played with sound. Without a sound card on the presentation computer, the video cannot be played with sound. Therefore, it is crucial to install a sound card to enable sound playback.

The other options provided in the question are not ideal solutions.

• Option B involves explaining the video to the class, which is not an effective substitute for actually playing the video with sound.
• Option C suggests creating presentation slides with screenshots from the video, which would not be an appropriate replacement for a video with sound.
• Option D involves performing a voice-over while the video plays, which would not be in line with the delivery method intended by the course designers.

In summary, the best approach to maintaining the delivery method intended by the course designers is to ensure that the presentation computer has a sound card installed before the class starts (option A).
