Question

you’re at home one afternoon watching your little sister lily, who asks you to help her put together a presentation for her scouts group. she’s trying to get a new badge for presenting an important topic. she chose to present on the effects humans have on oceans. lily wants to make sure she’s using multimedia (graphics, sound, and visual displays) that adds to what she’s sharing with her audience. the opening slide introduces the effect pollution has on marine life.

what type of multimedia do you suggest she use to grab the audience’s attention?

○ a text - only summary of pollution statistics
○ an audio recording of ocean sounds, such as of whales
○ a video clip showing marine animals in their natural habitat
○ background music to set the mood

Explanation:

To grab the audience's attention for a presentation on human effects on oceans (focus on pollution's impact on marine life), we analyze each option:

• Option A: Text - only summary is not engaging as multimedia (graphics, sound, visual displays) and lacks the visual/sound appeal needed.
• Option B: Audio of ocean sounds (whales) is related to oceans but doesn't directly show the impact of pollution on marine life.
• Option C: A video clip showing marine animals in their natural habitat can set the scene of a healthy ocean environment. Then, when discussing pollution's effects, it creates a strong contrast, helping the audience visualize what is at stake. This directly relates to the topic of marine life and the impact of pollution (by showing the natural state before/without pollution).
• Option D: Background music is too generic and doesn't relate specifically to the topic of marine life or pollution.

Answer:

C. A video clip showing marine animals in their natural habitat
