Multimedia and visual displays are useful when used with text sources because they add to our understanding of the information presented in the text. Here is a breakdown of each option you provided:

1. They have to be used with text sources: While it might not be a requirement to always use multimedia and visual displays with text sources, incorporating them can enhance the overall learning experience and grasp of the content.

2. They are different than text sources: Multimedia and visual displays offer a different form of communication compared to text sources. Visual elements such as diagrams, charts, graphs, images, and videos can provide a more engaging and captivating representation of information, making it easier to understand and remember.

3. They are better than text sources: Multimedia and visual displays are not necessarily better than text sources as both have their unique advantages. Text sources are crucial for providing detailed explanations and textual evidence, while multimedia and visual displays offer a complementary visual representation that aids in comprehension and retention.

4. They add to our understanding of text sources: This statement is the most accurate. Multimedia and visual displays supplement text sources by presenting information in a visually appealing and concise manner. Visual aids help to clarify complex concepts, improve comprehension, and engage learners by appealing to various senses. They can also provide real-world examples, illustrations, and demonstrations that facilitate a deeper understanding of the text sources.

In summary, multimedia and visual displays are useful in conjunction with text sources as they enrich our understanding, enhance engagement, and provide a different mode of conveying information.
