The correct answer is D. Mary has difficulties pulling up her Powerpoint presentation on the screen.
Explanation:
A presentation is a talk or speech about some specific subject or idea that involves multiple elements including the audience, the tools used by the speaker, space where the presentation is delivered, the evidence used in it, among others. Considering presentations are complex and the speaker will need to think of multiple elements, rehearsal is recommended before delivering the real presentation, this implies practicing the presentation multiple times to learn the ideas and organization of the speech, know the way of taking advantage of the time provided for the presentation, among others.
Some of these elements can be rehearsed in any place, but some elements require the speaker rehearse in the actual presentation space or the place where the speech will be delivered this includes learning how to use the space to engage the audience and learning how to use the materials or tools that are going to be used including presentations or materials display using technological devices considering the speaker needs to check if there is any problem with the technology or how to use it properly. Considering this, the scenario that indicates that a presenter did not rehearse in the actual presentation space is "Mary has difficulties pulling up her Powerpoint presentation on the screen" because she would have to practice in the place where she was going to deliver the presentation to know how to use the technology in it or if there was any problem with the technological device.
