$2.[6$ points$]$ Let R$($A$,$ B$,$ C$,$ D$,$ E$)$ be a relation.

Assumption: the functional dependencies A $$ C and A$$ E hold over relation R$.$

Let the following be an instance of a relation R$($A$,$ B$,$ C$,$ D$,$ E$)$:

Figure $1.$

$2\mathrm{.}1.$ Can you identify any other functional dependencies that hold over R$?$

$$ If no$,$ very briefly explain why not.

$$ If yes, give an example of such a functional dependency. If you provide a functional dependency

as an example, it should be a non$-$trivial dependency with no redundant attributes. No justification

is necessary.
