\item \self Consider the following declarative sentence:

\textit{``For every natural number it holds that it is prime if and
only if there is no smaller natural number, except for 1, that
divides it.''}

Model this sentence with predicate logic, as detailed as possible.
Clearly indicate the intended meaning of all function, predicate, and
constant symbols that you use.

Also, model the same sentence in propositional logic, as detailed as
possible. Clearly indicate the intended meaning of each propositional
variable you use.
