2(a)(i)True or False: We can make changes in the PDF version of any file.Show solution
Explanation:
PDF (Portable Document Format) is a read-only, fixed-layout format. Once a file is exported/saved as a PDF, its content cannot be directly edited using standard PDF viewers (like Adobe Reader) or presentation tools. To make changes, you must edit the original source file (e.g., *.odp* or *.pptx*) and then re-export it as PDF.
2(a)(ii)True or False: We can insert video and audio clips in a presentation.Show solution
Explanation:
LibreOffice Impress (and other presentation tools like MS PowerPoint) allows users to insert both audio clips and video clips into slides. This is done via:
- Insert → Audio or Video menu option.
These multimedia elements make the presentation more interactive and engaging.
2(a)(iii)True or False: The number of slides that can be added in a presentation has a limit.Show solution
Explanation:
There is no fixed limit on the number of slides that can be added in a presentation in LibreOffice Impress or similar tools. You can add as many slides as needed. The only practical constraints are the computer's available memory (RAM) and storage space, not any built-in software restriction.
2(a)(iv)True or False: Impress is a free and open source presentation tool.Show solution
Explanation:
LibreOffice Impress is part of the LibreOffice suite, which is a free and open-source office productivity software. It can be downloaded and used by anyone at no cost, and its source code is openly available. It is a popular alternative to Microsoft PowerPoint.
2(a)(v)True or False: The background and design of the presentation cannot be changed once saved.Show solution
Explanation:
The background and design of a presentation can be changed at any time, even after saving, as long as the file is saved in an editable format such as *.odp* (LibreOffice) or *.pptx* (PowerPoint). You can change the background via:
- Slide → Slide Properties → Background in LibreOffice Impress.
Changes are only permanent (non-editable) when the file is exported as a PDF.
