[Tex/LaTex] How to label lists


How do I implement what is shown below? If I just use "enumerate" each time, it doesn't get labeled (only the items get labeled).

Loading enumitem makes it easy to have a custom layout:

\setlist[enumerate, 1]{label=(\arabic*), labelsep=1.35em}
\setlist[enumerate, 2]{label=\alph*., align=left, labelsep=1em}


 \item \begin{enumerate}
 \item Mary dated $\Leftrightarrow$ John dated Mary
 \item Mary hibernated with John $\Leftrightarrow$ John hibernated with Mary
 \item Mary is John’s cousin $\Leftrightarrow$ John is Mary's cousin
