How do I widen the length of these rows in the Thank You page?

Please help me understand how I can change paragraph width. If you see below I get words on a second line and I want them up in the first row. Thanks in advance

The width of the container for the Thank You page is depending on the width of the form. I can see that there is a max-width set in the CSS.

.form-all {
max-width: 500px !important;
}

Here's a guide on how to inject custom CSS. Hope that helps. Thank you.
