Final answer:
HTML is better for monitor viewing, while PDF is better for print viewing.
Step-by-step explanation:
When it comes to text format, it depends on whether you're viewing it on a monitor or in print. For monitor viewing, a more flexible and responsive format like HTML is better because it can adapt to different screen sizes and allows for interactive features. On the other hand, for print viewing, a fixed format like PDF is better because it preserves the layout and formatting of the text, ensuring consistency across different devices and printers.
