To create two paragraphs of text separated by a horizontal line using HTML, you can use the following code:
<p>This is the first paragraph of text.</p>
<hr>
<p>This is the second paragraph of text.</p>
The '<p>' elements represent the paragraphs of text, and the '<hr>' element represents the horizontal line that separates the two paragraphs. When this code is rendered in a web browser, it will display the two paragraphs of text with a horizontal line between them.
