In the following MWE, I have defined `cabin` as the default font.

```
\documentclass[12pt]{book}
\usepackage[sfdefault]{cabin} 
\usepackage{lipsum}

\begin{document}
\thispagestyle{empty}
\lipsum[12]
\vspace{10pt}

% I would like to use the default font for this paragraph.
\lipsum[3]
\vspace{10pt}

% I would now like to restore the default font (cabin).
\lipsum[13]
\end{document}

```

The output:

How may I disable the main font in order to print the second paragraph *only* with the default font?

Does anyone know what the default font is? If it is not Times New Roman, how may I specify Times New Roman for the second paragraph only?
